Yes! Ok, this is the exact setup I am looking at even down to the color, and I see you share my passion for weight reduction. So I have a question: According to the Apex Website those wheels should weigh about 16.9lbs, and according to others on this forum the stock wheels weigh ~22.4lbs. That should be about 5.5lbs off per corner. Obviously cutting against that is the longer studs (~+0.2lbs per corner) and wider tires (.78lbs per tires according to the America's Tire website). This would net you about 4.5lbs per corner. Obviously the reality on the ground is different because you're seeing like half the reduction. Do you have any ideas as to where that weight might be coming from?
I only weighed two of the wheels. They weighed 17.2 lbs and 16.94 lbs. I meant to weigh the others but forgot to do so before going to the tire shop. I did weigh one of the tires and got 23.8 lbs. (tire rack provides a 23 lb weight listing on their website). After seeing the how much they vary from website listed weights I decided to weigh wheels/tire as a package and use that to determine the weight reduction for my situation. My scale may be slightly off to but I am trying to weigh everything on the same scale to give more consistency to my calculations. I would say majority of the weight is coming from the tires. I knew the tires would be heavier than the stock tires and molded parts tend to vary a lot more in weight than machined parts.

Yeah, variation in tire weight makes sense. Still obviously a very worthwhile upgrade. I was so excited to see someone run the exact setup I wanted (white car, bronze stock width VS-5RS, 245 tire), car looks great man!

A lot has developed, I was told at work (my department only) is mandatory work from home for a minimum of 3 weeks, the executives need to borrow our cubicles while their office space is remodeled. So I immediately thought this would give me a great opportunity to take my car out of commission and install as many of my planned upgrades as possible. I immediately started ordering parts. Now I can spend lunch break working on my projects, and no need to use PTO to sign for packages. I have already saved the money for these projects, I just didn't order anything before now because I don't like to get things until I am ready to start the project.
  • Xclutch Kit
  • Hypermax R Coilovers
  • SXTH Turbo Inlet Pipe kit
  • RacerX Carbon Rear support bar
  • Painted CE hood (actually ordered in June; is scheduled for delivery during my project/mandatory work from home period)
Lots of upgrades happening. I am going to try and post updates all at once and I want to put a basic guide together for the clutch install to help others who may be considering doing it themselves. And yes I am changing the clutch with jackstands in my garage. At this moment I am reassembling the car and the transmission is back in it. I have done 95% of the work completely solo, had to get help with separating the transmission from the engine, it is a tight fit, realigning the transmission with the engine (also very difficult due to the angle and the tight fit), and bleeding the clutch (which only took 10 minutes and was far easier than I expected).

I did weigh stock components and the replacement parts, here is a list of the weights of everything (will update as I get the final weights):
  • Xclutch (pressure plate and clutch disc): 12.68 lb; Stock: 13.42 lb => weight reduction: 0.74 lb
  • Hypermax Coilovers (front): 34.36; Stock: 43.04 lb => weight reduction: 8.68
  • Hypermax Coilovers (Rear): 25.04 lb; Stock: 19.88 lb => Weight Increase: 5.16 lb
    • Overall Coilovers dropped weight 3.52 lb and transferred weight from front to rear.
  • SXTH Turbo Inlet Pipe kit: 2.86 lb; Stock: 2.82 => 0.04 lb reduction (not significant at all but should allow engine to breath better.)
  • Racer X rear Carbon Brace: 0.84; Stock: 3.06 lb +=> weight Reduction of 2.22
  • Stock CE painted hood: 16.60 lb; Stock Premium/Core Hood: 15.04 lb => Weight Increase 1.56 lb (looks way cooler and should theoretically help reduce engine compartment temperatures)
Net Weight Reduction for this project: 4.96 lb, and car will handle better and I will be able to use all the power of my E50 tune.

Completed the install of my HKS Hypermax R coilovers (and clutch kit). Super happy with how it came out. The ride height is perfect at the default setting and alignment feels great. I will have an alignment performed next week to verify though. Feels like the car holds the road much better, but doesn't feel harsh. I am really liking the way it handles on the coilovers. While I had the car apart to do all the work I also gave my wheels a thorough cleaning and coated them in wax, hopefully this will make the brake dust come off easier with just high pressure water. Lastly I installed the racerX carbon rear shock brace. I have been eying this for a while and I am super happy with the quality of racerX's parts.

I got a notification that my Circuit edition hood was going to be delivered while I was working on the car. I ended up ordering it from revemoto. The paint match is excellent, my only complaint is the paint quality on the inside of the hood is no where near OEM and there is one chip in the paint at the edge (hardly noticeable) overall I would rate revemoto a 8.25/10. I ordered it on July 9th and it arrived on August 8th, not bad timing wise.

Disclaimer: This is a write-up on the overall process I went through to change the clutch myself. This is not a 100% accurate (meaning I more than likely missed minor or trivial steps.) I do not take responsibility for any issues or damages if anyone decides to change the clutch themselves. The intent is to give an outline of the process, to help others in determining if this is something they are capable of accomplishing themselves.

Clutch Install/Semi-Informal Write-up:


This was probably the 2nd biggest automotive project I have ever attempted. I did it with jackstands in the garage and it took 5 days to do (but I did also do some other work, so I could have probably done just the clutch in 4 days.) I am going to try an outline the steps I took and order as best as possible but once I got into the project I stopped taking notes and pictures. I tend to get hyper focused during projects and forget to take pictures. I installed the Xclutch Stage 1 kit (the one that retains the stock DMF). I also upgraded the bushing for my Delta X motosport pitch mount to the 70a while I was working on the car.

First are the lessons I learned:
  • Remove the d-shaft heat shield and the downpipe from the car before dropping the transmission; they will get in the way during the process.
  • Disconnect the drive shaft; leave shift linkage connected until after the drive shaft is disconnected
  • Removing the steering knuckles is easy (hang brake calipers with bungees); this will make it easier to drop the subframe
  • If you drop the subframe make sure that the steering linkage is disconnected, this can be done from inside the cab in drivers foot well, it is only one 14mm bolt that needs to be disconnected.
  • By dropping the subframe there is no need to remove the transfercase from the transmission.
  • No need to pull drivers side cv axle when dropping the subframe and the car doesn’t need to be as high because you can pull transmission out through the drivers wheel well
  • Drain all fluid from transfer case and transmission before pulling CV axles. This is critical.
Required Consumables (Items that will need to be replaced during the clutch install, I feel like I am missing something but these are the important bits):
  • 2X Axle Nuts - P/N 90080-17238
  • 1 qt 75x-85 GL% Gear Oil (0.49 qt capacity in transfer case)
  • 3 qts. 75W LV GL-4 (2.1 qt qt capacity for transmission)
  • 2X transfer case drain and fill plug gaskets - P/N 12157-10010
  • 2X transmission drain and fill plug gaskets - P/N 90430-A0003
  • Clutch kit of choice
  • Brake Fluid of Choice

To start I disconnected the battery and used bungee cords to hold the rear hatch open (so it wouldn't hit my garage door while on jack stands). My jack stands were set at a height of 21 inches (this seemed like a good height, I could reach most parts in the engine bay and it allowed for enough room to remove the transmission from the wheel well; remember you can change the height until you remove the subframe/lower trans mount). I then removed the air box so that I could gain access to the top of the transmission to disconnect the wire harness that is bolted to it, the shift linkage, the downpipe bracket and the transmission mount (this is the last thing to disconnect before dropping transmission.

Image


Next I started under the car. I disconnected the exhaust, the drive shaft, and the pitch mount. This is a good time to drain the transmission fluid and trans case fluid. Next I removed the wheel axle nut. It helps to disconnect the tie rod end and caliper to get more range of motion. You will also need to remove the two nuts and one bolt at the bottom of the control arm that attach the steering knuckle And unbolt the sway bar endlinks from the strut (Its fine to leave connected the the sway bar). Since I was doing coilovers too I just removed all of the suspension components to make it easier.

Image



Now I removed the passenger cv axle, there is a cast iron support for it that retains the cv axle with a snap ring like retainer. This can be removed with channel locks or pliers. Them there is a bolt sticking out of the bottom that acts like a set screw, this will need to be loosened. Important note: make sure you have drained transmission fluid and transfer case fluid before pulling out the cv axle. If not done this can cause the fluids to mix and require them to be flushed. Now you can carefully pull the cv axle.

Now you can start to drop subframe. Before dropping it make sure to disconnect the connector for the o2 sensor, it is attached in multiple spots. Disconnect the Steering input shaft from in the car and the dust boo can be unclipped from the car from the same area. Now there are two supporting beams that tie the subframe to the front of the chassis, each has 4 bolts that need to be disconnected. The passenger side one also needs to be unbolted from the hot side charge pipe going to the intercooler. Once you verify all these components are disconnected you can drop the subframe, it is attached to the chassis by the 4 bolt locations circled in the image below. This is heavy, use some kind of jack to support and lower it.

Image


Now if not already done make sure the transfer case output shaft heat shield and downpipe are removed from the car Now make sure all electrical connections are disconnected from the transmission, disconnect the slave cylinder, I disconnected it at the lowest point at the front of the transmission. Caution: All of the brake fluid in the Master cylinder reservoir will drain out, make sure not to hit brakes until the master cylinder has been refilled after the clutch has been reconnected. This seemed the easiest way since there was only one bolt attaching the hose at this location. Now go over everything to make sure there is nothing connected to the transmission and this is a good time to disconnect your shifter linkage. Now you can unbolt bell housing bolts. After removing the ones on the bottom side I would recommend getting a trans jack in there to support the transmission while removing the bolts on the top side.

Image




The above diagram shows the locations of all the bellhousing bolts. Bolts labeled A are 17mm and bolts labeled B are 14mm. I also circled the two starter bolts that need to be removed, these are also 14mm. The numbers are the order to tighten the bolts when torquing them during the install. There is a small plastic shield that is on engine side of starter, I would recommend removing this and setting it to the side to prevent from loosing it (easiest to remove once transmission is removed).

Once all the bellhousing bolts are removed you can unbolt the 4 bolts attaching for the transmission mount. Now you can slowly start to lower the transmission and break it free from the engine. Once you have successfully done this thre transmission can be removed from the drivers side wheel well. I would immediately recommend supporting the engine as best as you can so that the engine mount on the passenger side isn’t supporting the entire weight of the engine. I used a jack underneath and an engine strut tower support bar up top.

Overall the stock clutch was still in good shape, only reason I changed it was due to slipping at high RPM and high load on my e50 tune. The ridges in the flywheel and pressure plate are starting to smooth out (this has been well documented that there are ridges from Toyota). The areas that look like hotspots are the higher locations that have started wearing smooth. I did hit the flywheel with a stone and emory cloth to clean it up a bit before mounting the new clutch.

At this point you have access to the clutch. Once changed you just need to reverse the process to reassemble.

I intend to add more to this post, it is currently a draft in work.
Great write up so far! My 2¢ for the final copy, maybe add torque values to this for when you put everything back together because that’s a lot of bolts and nuts lol

Here is some of the toque specs required during reassembly:

The clutch pressure plate to flywheel toque is 14 ft*lb (the requirement for the Xclutch kit is 26 ft*lb due to grade 10.9 bolts being used). Per the repair manual snug bolt 1 then torque the rest in order, bolt 1 will be torqued when you get to it as bolt 2.
Image


At this point you have access to the clutch. Once changed you just need to reverse the process to reassemble. the overall order for reassembly for me was to get the transmission lined up with the engine then torque the bellhousing bolts followed by the starter bolts. Here is the page from the repair manual on torque order and torque specs. The starter bolts (not shown) are also the same torque at the 14mm bolts labeled (B).
Image



Now the plastic starter cover can be replaced (if removed, it clips into the engine). At this point I used the jack to raise the engine into place and attach the transmission mount in the engine compartment (there is a torque order for these bolts). I did find it easier to access these bolts with my torque wrench by removing the ECU, it is fairly easy to do.

Image

Now I spent time reconnecting all of the wire looms and connectors attached to the transmission, hooked up the hydraulic line for the throw-out bearing and bled the clutch. Next is a good time to reconnect the downpipe (recommend leaving mid pipe off until after re-installing the subframe). you have a lot more clearance to work on getting it installed and better access but it can also be done after installing the subframe.

Image



Installing the subframe was not that difficult, the hardest part of the process was connecting the steering input shaft. Here is a good post to reference on the torque specs for the subframe. I recommend using the jack to raise subframe into place, one it is close then reconnect the steering input shaft and the dust boots. Once complete reinstall the subframe, should have only need to torque 4 bolts, the torque specs are in the linked post at the beginning of this paragraph.

Image


No the two forward subframe supports can be repalced. Both attach to the subframe with 2 14mm bolts and attached to the chassis of the car with another 2 14mm bolts. The passengers side also attaches with 2 bolts to the turbo hotside charge pipe.

Image

At this point you can attach lower engine/trans pitch mount. Install everything loosely. Torque the 4 14mm bolts on the trans mount side first. Then torque the pitch mount to subframe bolt, lastly torque the bolt that attaches the pitch mount to the trans mount.

Image

Image

*image from DeltaX pitch mount install instructions. I added the toyota OEM torque specs where it is different. DeltaX specifies a lower spec due to the addition of the blue locktite.

Next part is to get the drive shaft reinstalled. When I disassembled the driveshaft I unbolted the 4X bolts on the transfer case flange and the 2x bolts supporting the carrier bearing (the heatshield needs to be removed to access those 2 bolts. The nuts for the drive shaft flange torque to 54 ft*l and the carrier bearing bolts torque to 27 ft*lb (be careful to have the spacers/support washer installed in the correct location (between carrier bearing flange and body of car). A diagram can be found in this post by maxg. Now the transfer case output shaft heat shield can be reinstalled, this attaches with 2 bolts torqued to 18 ft*lb.

Once the driveshaft is re-installed finish installing the exhaust midpipe and any heatshields that were removed. Once all that is done the 2 chassis support beams can be replaced, 4 bots on the front one and 8 bolts on the mid one. All 12 bolts torque to 24 ft*lb.

Now the passenger CV axle can be reinstalled (and drivers side if it was removed). Install the bearing support retaining clip first then torque the retaining bolt.

Once this was all completed I started reassembling the front suspension components. Here is a good diagram showing all of the component bolts and their torque specs. the swaybar endlink nut to strut torque spec is not listed the value I found was 55 ft*lb.

Image



At this point I reconnected the shift linkage, made sure I torqued down the downpipe support bracket, reinstalled the ECU, and reinstalled my airfilter assembly. Now I double checked everything made sure I staked the axle nut after torquing and reinstalled the wheels and connected the battery. I test started the car on jack stands to make sure there were no errors (probably not the safest thing to do but I felt comfortable since the jack stands I used were incredibly stable.


Special thanks to these members of the forum, I was able to utilize information they posted to help with researching for changing out my clutch (I also linked the posts for reference):

I intend to add more to this post, it is currently a draft in work. I believe I have everything in here to be a basic guide, I did leave off trivial thins that should be obvious when doing this kind of work. I tried to remember the order I did things as best as possible, I did reorder a few thing that I discovered should have been done at a different point in the process.

Overall the stock clutch was still in good shape, only reason I changed it was due to slipping at high RPM and high load on my e50 tune. The ridges in the flywheel and pressure plate are starting to smooth out (this has been well documented that there are ridges from Toyota). The areas that look like hotspots are the higher locations that have started wearing smooth. I did hit the flywheel with a stone and emory cloth to clean it up a bit before mounting the new clutch.

Damn i wantsd to do a blend tune but seeing the work you just did. Ugh scares me. 😨 how can i test for slippage

Damn i wantsd to do a blend tune but seeing the work you just did. Ugh scares me. 😨 how can i test for slippage
I felt it slip 3 times under hard acceleration, around 6500 + rpm, didn’t check the gauge when I felt it. It didn’t happen every time, and I only ran two tanks of e50 before I had to go back to 93. Had no issues on my 93 tune. It is an e50 tune and it is making 340 wheel torque, I have heard the max holding capacity for the stock clutch is around 350-360 torque at the crank. I was already planning to upgrade my clutch I figured, I was forced to do mandatory work from home for three weeks so I figured that would be a good time to do this project. I am more of a diy person, if I lived closer to limit +1 I would have probably paid them to do it, I don’t have any shops in my area that I would trust to work on my GR either.

My clutch should be broken-in by now, Im just over 600 miles on it. Have been doing a lot of city driving and backroads with a lot of stop signs. Once I burn through my current tank of 93 I plan to switch to E50 and give it a good test.

I got my alignment completed and I signed up for my next track day. Planning to go back to Hallett in September. Looking forward to seeing how much better the car will handle along with my improvements from my last track day at OIR.

Not a whole lot new, just driving the car and preparing for my next track day. Going back to Hallett in September. With the improvements I made in my braking at OIR and the improvements I have made to my car/my driving overall, I am hoping to get a lap time below 1:40, for reference my best lap time last time was 1:41-1:42 approximately. I had to use timestamps from my gopro to estimate. This time I bought a legit lap timing device (Garmin Catalyst) since I have now been approved for solo.

I have switched back to E50 fuel/tune. Went to my favorite gas station ( they sell ethanol free 93 oct. and E85). When I tested the E85 was getting 62%, had to drive around and find another station, with the amount of fule I had in the tank there was no way I was going to get to E50 mix. Ended up filling up at a station that there e85 tested 70% and the 91 oct. tested 8%. I tested out the clutch with several High load/RPM pulls and quite a few flat foot shifts. It is holding the power, no slippage whatsoever is being detected. I am going to run E50 for a little while and enjoy it but I plan to go back to my 93 tune for my track day.
 
I installed my new tires and wheels. I got the Bronze Apex VS-5RS and the Continental ExtremeContact Sport02 in the 245/40R18 size. These wheels look amazing. I did test fit the wheels ahead before doing the extended studs and I got 4.5 turns in the front and 5 turns in the rear. Definitely needed to go with the extended studs.

After researching I decided to go with the ARP studs, which would require removal of the rear axle bearing. The front was easy enough all I needed to do was bend the brake shroud, which I didn't like doing but after dealing with the axle nut on the rear I decided I was best off taking the least invasive route. As stated I went with the ARP wheel studs, I also bought Professional Awesome Titanium Lug Nuts, and 2x replacement Toyota Axle nuts.

This installation took about 6 hours to complete, I was expecting 3ish hours. I foolishly decided to do this during the week rather than weight for the weekend, since the last of the tools I needed showed up from amazon and I have been waiting to do this ever since I ordered the wheels in April. The tools I ordered were the lug nut installation tool, Toyota 30mm axle nut removal tool (comes with the tool to remove the stake) and a axle nut staking tool.

De-staking the axle nut was the most stressful part. Need take your time to make sure that the staked portion does not touch the threads when unbolting. Removal is easier with an impact. Need an impact to install studs as well, I would not recommend doing studs yourself if you do not have access to an impact wrench. The next most difficult part is getting to the 4 bolts attaching the hub assembly, I had to get creative with extensions, including use of a wobble extension.

Torque specs:
  • Rear Axle Hub Bolts, 4 per side: 66 ft*lbs
  • Brake Caliper bolts, Front and Rear, 2 per wheel: 79 ft*lbs
  • Rear Axle nuts: 159 ft*lbs

I did weigh everything before install and weighed all of the stock parts as well:
  • ARP Studs per set of 5: 0.70 lb
  • Professional Awesome Titanium Lug nuts per set of 20: 0.88 lb
  • Weight of each wheel and tire: (41.40, 41.10, 41.08, 41.40) = AVG of 41.245
The Weights of the stock parts:
  • Front Studs per set of 5: 0.47 lb
  • Rear Studs per set of 5: 0.53 lb
  • Stock Lug nuts per set of 5: 0.76 lb
  • Weight of each wheel and tire: (42.86, 42.82, 43.22, 43.18) = AVG of 43.02
Total weight savings for this install was approximately: 8.44 lbs of rotating mass.

Amazing rims! I'm also interested in the Apex VS-5RS in the 18x8.5 ET23 size (I assume you have the exact same spec rim) in combination with a Morizo-size 245/40/18 tire. Do you have any issues with speedometer error/ABS issues with the slightly wider and taller tire? I would assume any difference would be negligible. Also, do the Apex rims not come with any kind of center cap? Thanks!

Yes that is the fitment I bought. The wheels did come with center caps, I just didn't install them since I will need to take them off for track use. I also prefer the look without centercaps. I had zero issues with ABS or any errors. The width fits great, no rubbing issues either. The speedometer error is negligible, it is reading closer to actual than the stock tires. It is only 1.2% difference is circumference of this tire vs stock.

I have not done a lot to the car lately. Been driving it and enjoying it. I went back to my 93 tune in prep for my track day this weekend (no E85 available near the track). I really miss E50. Looking forward to getting back to Hallett, this time I will be attending with APEX Driving academy. I also signed up to go back to OIR in October. To make the most out of my upcoming track days I invested in a Garmin Catalyst. I feel like this should be a good way to see if I am improving and help me get better.

I removed the d-rings in the rear storage area for a little bit of weight reduction. I am splitting hairs here but again I never use these and never will use them so it is dead weight, might as well remove them and get a 0.43 lb reduction in overall weight.



I did install an AJT keyfob (the one for the Tundra/Tacoma LINK) I really like it. I only bought one since I was not 100% sure it would work. I weighed the before and after weight of the keyfob and it was identical so that is also a plus. I have some AJT keyfobs on my 4runner for years and they hold up well, I really like the quality of their products.



I also added a quadlock for securely mounting my phone for data logging purposes on track. I forgot to get a weight (will try and get one later on) I estimate it adds 0.20 lbs for now but will later on get and official weight addition. I do like this system, it keeps my phone secure and allows it to be in a position that I can run the ecutek app to data log and monitor some of the sensors with the dashboard.

Have fun! I have heard great things about the Catalyst! Onboard GPS data is such a fantastic tool for learning as a driver. If the chance presents itself (and you're comfortable with it) have a pro driver or driving coach take your car out for some hot laps and then compare their data traces to yours to see where you can pick up speed.

I have been traveling a lot and not had time to post. I have quite a few updates to post, I am going to try and group them together here and then do a separate update on my previous two track days.

Review (Revemoto), Painted GR Corolla CE Hood, 1.5 out of 5 stars:
-Paint Quality 0 out of 5
-Customer Service 2 out of 5
-Paint match to OE color 5 out of 5


Do not buy from Revemoto. To start their customer service is complete crap. They claim OE or better quality paint. If you have had any Toyotas over the years then you know their paint is not a high bar. I have had this hood for less than 3 months (about 3500 miles and 2 track days; For comparison I have 0 chips on stock hood with 7500 miles and 3 track days) and the paint is chipping significantly in multiple regions. It is not cost effective to send this hood back for lifetime, I contacted them about a partial refund to use for local paint repair. It was difficult and took a lot of back and forth to get some money back (this was 2 weeks into owning the hood).

These are not rock chips, the paint is chipping in large chunks and delaminating from the base layer. See pictures, you can see either paint or primer where the chips are not bare metal. The simple fact is I wish I just bought an unpainted hood from Limit+1 and had a local shop paint it for me. Now I am out more money and I have to find a shop to have this hood repainted.

SXTH Turbo Inlet pipe, 3 out of 5 Stars:
-Quality 4 out of 5
-Customer Service 4 out of 5


The install is a bit of a pain. The overall build quality is good. My gripe with this product is the seal material spec'd for the turbo Inlet adapter. I was doing a pre-track day inspection and saw this:

Image


I thought I had mis-installed the inlet adapter and pinched the seal. Upon disassembly I realized it had melted and that I had seen some seal material that had oozed out from between the two surfaces. My concern is the potential for hot melted rubber to be sucked into the turbo.

Image


This is clearly not a high temp seal and has melted with about 3,500 miles of driving. They do not sell a replacement and their recommendation is to buy one at the hardware store. The stock toyota seal is high temp, I compared it and it has no deformation with 7,500 miles of use. I am going to try to source a high temp seal to replace the melted seal. Iwent back to my stock one temporarily for my track event. I did notice that Intake manifold temps have dropped with the stock one. This leads me to believe that the Aluminum one is heatsoaking more than the stock plastic unit. If I do reinstall I will probably wrap it with the gold foil tape to reduce heat transfer.

Track day download:

To start I have new information on the AWD shutdown/Overheat. I have finally hit a true shut down at Ozarks International Raceway this past weekend (I think everytime I got the message previously it was the warning not the official shut down). I have thought it shut down on me multiple times in the past but I never noticed any difference in handling. At OIR I got the message then half a lap later the message changed and the car became nearly impossible to drive under hard throttle. The rear end became Loose under throttle (thought this was unusual but another GRC owner at the track had the same experience). My theory is that it was unable to transfer enough weight to rear end to get rear traction.

Before these track days I changed the engine oil to 5w-30.

Hallett, September 21-22, 2024, Apex Driving Academy:

This was a hot we hit mid to high 90s on the first day and then got some rain on the second day. It was fun to learn the wet line a bit at hallett. On the first day I hit the AWD overheat (at least what I thought was the overheat) every session usually within 2 laps of the end. I got a new PR at the track during the second session of the day at 1:35.72 (was previously aprox. 1:41). From there I got progressively slower. I believe this was in part do to my instructor. He was teaching me a line I did not feel comfortable with that was difficult for me and my car to hit consistently. He was a good driver, he just was less familiar with the track than my previous instructor (in June).


Day 2 was fun. I was nervous with the potential for rain. During the 2nd session it started as a light sprinkle and by halfway through it was a fairly decent rain and the track got progressively slicker. This was a fun session and the only session I have ever had at Hallett without triggering any AWD overheat messages.


Here is a link to the full playlist of all the videos I have from Hallett in September.

Ozarks International Raceway, October 19-20, 2024, NASA:

The temps overall for the weekend were 50-60s in morning with afternoon sessions being 85-90. I had a great time. My PR from my previous event here in July was 3:42 and my goal was to break 3:30. Which I did almost immediately. On the first day my fastest lap was 3:07.10 in my 2nd session. I triggered the AWD overheat once and it was in session 3. About half a lap after the message (that I thought was the overheat) the message changed and the car became undriveable. It started oversteering realy bad on track out.


Day 2 was the most fun of the event. Session 2 I was chasing behind an Camaro SS and doing 3:08 - 3:09 laps, this was crazy fun. He was faster than me in some spots and I was faster than him in others. Specifically turn 2 to the entry of turn 4 and turn 8 to turn 11. Towards the end of this session I hit the overheat again and half a lap later I experienced the same handling issues.


In session 3 I set my PR for the weekend at 3:03.62 after speaking to another much faster GRC driver I change my driving a bit in this session. I was following behind the instructor (who was another GRC owner that was much faster than me). No overheats in this session but my brakes did get soft going into turn 16 on my PR lap. I had to back off a bit and I think I lost about a second. No AWD overheat in this session or session 4. It should also be noted that the Camaro I was chasing in session 2 set his PR for the weekend in session 3, I believe he said it was a 2:58.


Here is the full playlist of all the videos I have from OIR. Overall this was a fun event, I want to maybe get a few more track events on this car and try and see if I can alter my driving a bit to reduce AWD overheat instances. My front brakes are (track pads) are almost worn out with 3 track events on them so they will need to be replaced soon.
