If it happens when a wheel begins to rotate, it could be a brake pad clunking back and forth in the caliper, but I would expect you'd likely hear it again moving forward.

Was gonna say this!

I ordered a few of the parts and they were on backorder so it took a month to receive everything. Finally got around to installing the following

2025 Steering Column Bolt (x1): 90119-10A34
This was easy to install, just need to remove the lower panel where the ODB2 port is, loosen the air duct, and remove the brake light switch. The original bolt head was a 14mm, the new one is 17mm. I couldn't fit my torque wrench in there so I just tightened it by hand but made sure it was solid and tight. Old bolt is left and new bolt is right

2025 Clutch Spring 31394-12090
This was a pain in the ass to remove and install. I'm weak and couldn't compress it by hand, I even tried throwing my purse at it and boy that didn't work either, not sure why everyone recommends that... To remove the old one I just forced it out from the side that sits on the clutch pedal... unfortunately I broke the bushing and had to purchase a new one so proceed with caution, luckily my dealer had them in stock. To install I compressed it by wrapping the top portion with a rag and used pliers, after it was compressed I used safety wire to hold it, replaced the bushing and holder and it went in fairly easy, then I snipped the safety wire and done.

old spring is right in blue and new spring is left in white

2025 Rear Shock Absorber Upper Mount Bolt (x4) 90109-10194
this was probably the easiest to install. Just jack up the wheel, and replaced them one bolt at a time to avoid any potential movement, they are tapered so it shouldn't be an issue either way. The torque spec is 44 ft lbs

old bolt is left and new bolt is right with the 10

2025 Lower Ball Joint Bolts (x2): 90105-12429 - original post stated 4 but it's actually 2, I now have an extra 2 if anyone wants them, just pay shipping and they're yours. These took the longest to arrive, literally a month after I ordered them.
Install was easy, I did it one side at a time, jack up each side and remove the wheel, remove the bolt and reinstall. Also double check the ball joint nuts, one of them wasn't fully torqued down on the driver side. Torque spec is 66 ft lbs for bolt and nuts

old bolt is the right one and new bolt is the left with the red. both show 11 at the top but the new bolt has a little dot next to the 11

2025 under tray full assembly 51410-12200
this has been covered so no need for pics

2025 under tray service cover 51410-12070 - I also ordered the service cover because they said the full assembly was on back order with no ETA and the service tray would arrive in a few days... full assembly arrived in 3 weeks, so I have the service cover sale if anyone is interested lol

my car is a 2024 Premium. After the install I took it for a drive and WOW, If I do say so myself the car feels... exactly the same. I wasn't expecting any difference, I mainly did it to have the latest parts to calm down my OCD and not sure why but I was kind of hoping the ball joint bolts would've solved a slight clunk I've been hunting down that occurs only when I'm reversing, it's kind of like something is shifting somewhere down there. I've retorqued the subframe, all visible bolts, installed the delta x pitch mount 70a, and unfortunately no luck...

Maybe some are more sensitive to the rigidity of the new parts and can feel some sort of difference or maybe when tracking the car or driving hard they become pronounced and noticeable. My car is a daily driver and I don't beat on it so I really didn't feel any difference.

Thanks for this info. Happen to have the PN for the clutch spring bushing? Thx!

I am ordering a new GR. The website shows a sub-radiator as an option only for the Premium,not for Core or Premium Plus. And it can be ordered only as part of an unspecified options package. The guys at the dealer think that the sub-radiator is an enhancement for the audio system! Can you explain?

It isn't an option for the PP because it is standard on the PP.

And the guys at the dealer are unfamiliar with the product they are selling.

Yup, sub-radiator is an option on the Premium and standard equipment on the Premium Plus. It is not available on the Core model. My ideal spec was a 25 Premium with the sub-radiator but my dealer was just not getting a lot of Premiums with the sub-radiator option. I eventually went with a 25 Premium Plus as the sub-radiator came standard. The only "downside" was that the Premium Plus comes with the carbon fiber roof, hood vents/bulge, and HUD display that I did not necessarily want or need. (I was hoping for a more stealth appearance for the car.)

 

[Walt]

Thanks for the info,guys.

 

[GizmoGR]

Thanks, do you think it was pulling the spring sideways rather than compressing it that broke the bushing?

Yes I believe pulling it sideways broke it. I noticed that if you look up the part number 90389-06055, on the Toyota website on the diagram it says non-reusable part on the bottom left.

I do hear a loud clunk when reversing and turning the wheel so I guess that's the pad, but the clunk I'm hearing also happens when I'm reversing straight back and then when I pull forward but not as loud or noticeable as when reversing. I'll probably check it out this weekend and tell my wife to reverse the car and I'll stand outside and check it out.

actually both Ohlins and KW’s are more expensive than the GR Performance suspension. It’s not cheap but it’s not as much.
I choose Annex instead of either of those, KW are old tech that’s never been updated. Ohlins can be good but their square 9/9 spring rates raise’s questions in my book . It’s not a proper front to rear spring rate for our cars, Annex actually worked all this stuff out. I am sure this comment will bring the Ohlin boys out of the woodwork . All can say is go study front to rear suspension frequencies for our cars you will find out springing 9 front with 9 rear is springing the rear to soft to the front ratio wise .

Which annexs did you get? There are a couple different options. Are the clubspec pros good for the street and what about the upside down camber plates?

I got the Fastroad Pros which are good for street , canyons etc plus occasional trackdays. Clubspecs are track oriented not as much towards street use . Camber plates are up top even though shock is inverted . Shock adjustment is on the bottom. The l brackets on the bottom are slotted for adjustment . I had MeisterR’s on FiST that were the same way had no problem dialing in desired camber.
They would be in my car already but I am leaving for Japan in two days and pretty much decided to wait till I got back before installing .

The hood bulge has been changed, does anyone know the part number?

 

[ijuswannaride]

Really? What's the difference?

 

[DylanJZA]

Really? What's the difference?

Yeah, my 25P+ hood looks the same to me as the 23/24CE

 

[nino]

Sorry, I might have misunderstood.
I thought watching a video of the MY2025 with bulges.
Maybe they were just explaining the difference with the CORE.

 

[youngtl]

For the MY2025, there were quite a bit of revisions to the suspension as well as cooling. I have created this thread to document all parts that are compatible with MY2023 and MY2024 vehicles, pending actual confirmation. If any information is inaccurate, please let me know and I will address.

View attachment 30895

The ATF cooler will not be relevant to MY2023 and MY2024. The sub-radiator seems to provide auxiliary engine cooling, but it does not actively cool the transfer case. Quite honestly, it's better to get an aftermarket radiator as any cooler additions would require the MY2025 front fascia. If you are so inclined to retrofit the sub-radiator, see @st165's post below:

Sub-Radiator Part Numbers

The most interesting change is the transfer case cooling duct. Per Chief Engineer Naoyuki Sakamoto, this change will not solve the AWD overheat issues, but it should help.

Engine Service Cover with Duct: 51405-12070
Main Under Cover with Engine Service Cover: 51410-12200

These changes are all made to help reduce squat and dive; therefore, reducing understeer characteristics mid-corner and on the exit of corners. The rear sway bar was likely changed to accommodate the new springs. The most important change is the rear trailing arm mount as it is an actual suspension geometry change:

Front Shock Absorber (LH): 48520-80832
Front Shock Absorber (RH): 48510-80C88
Rear Shock Absorber (LH/RH): 48530-80B99
Rear Trailing Arm Mount (LH): 48727-06060
Rear Trailing Arm Mount (RH): 48717-06030
Rear Sway Bar: 48812-12580
Sway Bar Bushings (x2): 48818-12440
Rear Coil Spring (LH/RH): 48231-12N20

Finally, some more bolt changes to add rigidity to the suspension and steering system:

Lower Ball Joint Bolts (x4): 90105-12429
Steering Column Bolt (x1): 90119-10A34
Rear Shock Absorber Upper Mount Bolt (x4) 90109-10194

@KanmuriDavid

I think you only need 2 bolts for the Lower Ball Joint Bolts: 90105-12429

So the 2025 clutch return spring part number is not showing as an actual part on all the Toyota parts websites. Can someone verify that the part number is correct?
