Might be a good idea to stick up what size wheels your looking to run , weather 16's 17's 18's
Exhaust is pretty pointless on the newage 1.5 cars . sounds like a bee trapped in a coke tin ,wont give the rumble like the turbo cars
some of the breakers listed in the traders section may be able to help with the mirrors and springs and maybe wheels 2 , any newage morrors from a blob or bug should fit ,
