I have the S1 and yes Ive replaced the ball cups into tamiya, replaced the topdeck to a carbon fiber coz I broke my stock topdeck. Ive shimmed some parts to eliminate the slop and thats it. I also want a T4, its avery nice car. But sadly now I can only afford the S1. And its doing a very good job for me so far ...
