@spartans86 Thanks for the feedback! I’m glad to know that you are enjoying the benefits so far
👊😎

The bushing durometer’s are spot on as shown in the pictures on the original post. The issue is the bushing insert. I sent 2 cad files to my machine shop throughout the development and they ended up producing the wrong ones -.-

The surface area of the insert you are using right now is too large and it is crushing too much of the bushing which in turn absorbs a fair amount of flex…therefore making the bushing harder than it should be. That’s why you notice increased NVH at this time.

The correct versions are being produced now and will go out to all of the past, current and future orders on October 22nd, after I return from my out of country vacation.

So everyone is aware I did inform Spartan of this issue before sending it out to him. Just a little FYI Spartan, the 70A is not affected as much as the 60A with the bushing insert since it is already a harder bushing, so if the idle NVH is bugging you too much for the next 3 weeks (until I send you the correct insert) would recommend swapping to the 70A. The frequency of NVH will increase but the harshness will be less if that makes sense.
Ohhh ok I misunderstood but that makes perfect sense!

Whats the status on these? How hard is it to go from each setting?

I just got back from my vacation yesterday so today I will be picking up the revised/correct bushing sleeves. All back ordered/pre-purchased mounts will be shipping in the next few days as early as tomorrow. Installation will range from 15-30 minutes once the front is of the ground depending on if hand tools or power tools being used. It will take the same amount of time to swap out the bushings to a different duro.

Sounds good, please let me know if there is stock available to order and how to order!
 
Update: After installing the proper bushing mount it is perfect. Super happy with it. Feels great and the added vibrations are very minor, my wife doesn’t even notice any difference from stock. But driving and shifting are greatly improved. Thanks again!

Thanks for chiming in! You are a tough cookie to have endured the set up with the previous bushing sleeve 😅 I’m glad to hear you are happy with it now and that you feel the pros do out weigh the con of the added NVH. Sadly there is almost always a Trade-off when adding a performance part.

I have less than 10 remaining in this batch if anyone else is interested 👊😎

I installed mine today and I am very happy with it.
One thing I didnt like about this car was the awkward clutch pedal work that had to be done to get the car moving from a stop and then also the challenge shifting smoothly into 2nd gear in anything but an aggressive acceleration. The pitch mount alleviated all of this. It shifts smoother, and i dont have this issue anymore. In shifting does feel a little better as well, especially down shifting. I have only put about 30 miles on it, but I am very happy so far. The NVH is a little noticeable BUT only at idle and I know it will dissipate as I have installed many stiffer motor and tranny mounts in my past cars and usually within a couple hundred miles it reduces noticeably. The install was easy, the instructions straight forward and very helpful, love that the torque specs are included for every bolt. I seem to have a collection of DeltaX parts building. Looking forward to the next great product. Now I just need to figure out the occasional grind going into 2nd gear when accelerating hard from a dead stop and shifting fast when turning onto a busy road. It doesnt happen all the time, but seems with the side loads of a sharp turn, and 1st gear accel the tranny moves enough that the shifter alignment and possibly some effect on the clutch/pedal throw has caused a grind. I will just lay off that and shift slower but not something i have experience on my other sporty cars.

Ps I wrote on the bushings in paint pen.

You didn’t waste any time! Thanks for the update and the initial review. If you are still experiencing the grind while corning it might be worth a try moving up in Duro to keep it a little more flat or possibly give the solid shifter bushings a try. I may have a batch made on the next batch of pitch mounts since they are a very simple design but a few companies have already released some. Maybe worth looking into in your case.

One thing I failed to mention to everyone is the poly bushings will require a break in period to get settled. I don’t have an exact number but from similar products a few hundred miles up to even 500 miles seems to be the norm. I’d really like to hear everyone’s feedback once you achieve those numbers as I have one customer that seems to be having more NVH than most upon initial install that I’m monitoring closely.

I don't think I need a stiffer bushing in the pitch mount, but I'll let that in mind. I think I'll try the cable bushings, thx for that suggestion. Trying to decide on ones with a spherical bearing or just solid bushings.
Any thoughts on which approach might be better?

My experience with the break in was that after a just few drives the NVH already had dramatically decreased. After almost 500 miles of it slowly decreasing I would say it was broke in. I drove 800 miles yesterday and halfway through I was feeling ready to up to the 70a bushing because I could feel more movement wanted it to be stiffer. Going to try that when I get back from my trip. My results may be slightly skewed since I was using the v1 insert until right before my trip
 
I agree with @CHEEKY GR-E210.
I have the Racer X Fabrication bushings and they are perfect.
Good to know, thx for that additional input.
I know the one kit has solid bushing mounts for the shifter base itself. Any thoughts on that? Curious how much that might actually help or if it would transmit more vibrations than it's worth.

Nice! Thanks for another update. If you do happen to swap out to the 70a let us know what you think about it.

BTW here in a few I will be posting about an installation update and also sending out new instructions to everyone who has purchased to this point.

It was pointed out to me from a Toyota Master Tech that the bracket going to the Trans actually has a specific toque sequence that keeps it aligned.

INSTALLATION UPDATE

It was brought to my attention from a 13 Year Toyota Master-Tech that as per the Toyota Datum the 14mm bolts that attaches the bracket to the Transaxle in Step 5 must be tightened in sequence to ensure alignment to the design specifications. I have attached a .jpeg of the updated instructions. Also added is the approximate bushing break-in milage for to the NVH to settle of 500 miles. The new instructions will be sent along with any new orders after today and I will also be sending them via DP/PM to anyone who has already ordered.

Good morning guys I installed the pitch mount yesterday at the same time that I installed a power brace and I can say that for anyone that may be on the fence about getting one of these mounts that it looks and feels like good quality stuff and the fact that we can change out the inserts is a plus in my opinion. I can’t speak from a long term review perspective since I just installed it but I went with the 60a and 70a options and the 70a was already inserted in the mount so I just installed it with those to see how it feels and I can say that with the 70a there is a lot of NVH at initial take off. Once I was driving it was better but on every initial take off from 1st and idle there is significant NVH. Jeff told me that there is a 500ish mile break in so I’ll see how it goes and I can always go down to the 60a. Once I hit 500 miles I’ll let you guys know how the 70a feels.
