The TT02-R Godzilla GTR. Since I cant really post anything yet, here's a link to my Reddit profile with lots of pics and videos of the GTR and a few pics of the new Audi as well.

Did you put anything in your diffs? My TT02 stock diffs are not sealed, so I opted to put extra sticky grease in there to make it feel more like a tight ball diff. There are sealed aftermarket diffs out there for the TT02 if you want to experiment tuning with silicone oils.

Thanks for info TurboThirdGen ! I might try to ditch the shims too and see what results I get.
I've been having a blast with mine (plain old TT02 GR Supra kit) over the last few weeks. Built and tested fully stock, except for the shocks-- Those were awful, but luckily the fancy oil filled internal spring dampers I had from a fail project fit perfect and work great!
While the steering slop is a bit maddening, I've been having fun adjusting and tuning, and shimming. After a few rounds of testing, I trimmed down that center driveshaft cradle thing (D10 or D15) so the steering arms would stop hitting it. I also dropped in the alu. drive shaft, prop joints, 25T pinion, and 10.5T sensored brushless HW quicrun. Ditched the servo saver and just running no saver for now (will upgrade eventually). and .... WOOOOOOO!!!!! No idea on mph, but it feels great and very fast. I'll be going back to stock electronics when everyone in my group is ready for the spec racing.
I ordered the RcAidong Steering kit ($30)- mostly because I wanted a kit that included adjustable turnbuckles and wasn't over $50. I was almost going to order the YR kit, but no turnbuckles were included in their $25 kit. Also have the high speed gear set on the way too.

I'm using standard TT02 diffs. Lock block in front and JBweld plastic locked rear diff. When it was locked front/open rear, it would absolutely destroy the rear tires in short order cause they were spinning faster than the gear diff could handle. Plus there was top end fall-off. Its a speed runner/basher for onroad.
Futaba GYC441 gyro on AVCS mode about 30%.
My instability I believe is shim/shock issues. I've wound up with the top E-clip in the same shock coming off twice. I'm sure using the droop sleeves in the new CVAs should help too.
Its the torque steer being multiplied over 3/4 throttle. Waiting on it to dry out a little more to test this out.

I picked up another Tamiya TT-02 this morning, this time a White Special built but never run with the silver can motor and Tamiya ESC as a rally car with the Mitsubishi Lancer body . The blue camo colour scheme and striking looks nice. The previous owner had installed a YR light kit in the body and everything checked out perfectly. Just need to glue the tires and she's ready to attack the dirt trails.

Honestly I feel like the 2 Tamiya steering kits are the only way to get steering without slop. I'm sure there are other setups that are good, But I haven't had those yet to tell for myself.
I think the YR steering can be tightened up by installing matching bearings top and bottom of the steering bridge, As it looks like thats where most of the play comes from. Unfortunately the YR kit only comes with 2 bearings for that location. I've tried countless shims and spacers to clear it out and couldn't, so for the rally build I'll most likely grab the full Tamiya kit with high torque servo saver. I did however file the collars for the center bearings so the nuts I used on the top actually sandwiches the bearings without binding.
Then maybe I can mess with the servo savers plastic block and find a solution for that. Honestly if the block that the springs rode against was metal, It wouldn't wear so severely after a few hits. No idea why Tamiya didn't make the back piece metal too.
I run the Type S steering setup on the TT02R and couldn't be happier with that setup. Not the TT02-S steering.
The YR setup being so sloppy isnt that much of a big deal on the rally car but I like slopless setups when available.
Waiting on PS metallic red and PS white to finish off my Tommy edition Evo VII body for the rally chassis!
Unfortunately the matching wheels are no longer available. Tamiya 50724 PIAA Accord wheels :/

Instead of buying a complete set, I would suggest to get aTT-02R and the body separately.
TT-02 R comes with a lot of the needed hop-ups (shocks, bearings, high speed gears, rear toe in hubs, etc.) right out of the box.
Pimping a standard TT-02 up to the same level will create higher costs....

Spidermoss is bad enough outside when it gets wrapped up in the wheels!
