I believe thats exactly what they did, change the car to what the team drivers were doing. They would cut that rear upper brace to give the car equal flex on both sides. Also I think the new shocks have a greater tolerance between the piston and the shock body, thats been a problem for a while. Don't know too much about the top deck though. Looks like they have redesigned stickers, thats a great development. I was getting tired of the look of the older TRF stickers. Can't wait to put those on my car.
