Just finished my TT02 S-Spec kit. I set it up for VTA 25.5 but have not had it to the track yet.

Small changes I made from the kit:

Aluminum Steering Arms and middle connector
Aluminum center shaft
High Speed Gear Set (75/50 currently but yet to test at track)
Gear cover opened up to clear the 50t pinion
Shocks length set to 60mm front and 59mm rear. To do that I used 2mm front internal shock spacers and 2.5mm internal rear.
That gives rebound stroke about 2mm in rear and 3mm in front.
Moved rear shocks to outer lower mounting hole (otherwise car was too high even with no spring spacer)
2mm spring spacers front and rear gives me about 5mm ride height with VTA tires
I shortened the wheelbase at the back by moving the 3mm spacer (just to fit my existing body)
I shimmed to front and rear lower a-arms with some .2mm shims to take up play.

As a basic setup I put 1.5 camber all around. 1mm toe out in front.

I just kind of guessed based on how I have my 419 and 417 setup. I may get to run at the track this weekend.
