@JD Skyline:
I haven't driven the NSX body yet.
My guess is that the Super GT bodies (GT500 class) come out pretty equal in terms of balance and performance. The Lexus RC-F looked pretty much the same in close racing.

About the breaking issues:
The TT-02 is my first plastic car. And so far it appears to be pretty bulletproof. We had some hard crashes when parking-lot-racing and the car took it without damage. In comparison to my T4'15; I wouldn't be sure that the Xray is tougher...
