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.
Yeah you can totally omit that DS cradle from the build. It's only for steering limiting.
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 :/
