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.
