my Supra
 

it seems that my brothers civic and mt brothers skyline are both faster than my supra. i cant understand why. i think on monday i am going to take it in and trade it on a new one. do you guys think its a good plan?

edit- all cars are stock and mine just seems to never go into the high rpm. the controller is fixed to fast speed. i dont understand why my car feels like the batteries are always dead. any help would be apreciated, thx

did u try putting new bats in?

check your rear differential and your motor mounting.

You might have some cruft or something caught in it. Or got some hair or something wrapped around an axle.
