no i think those are all personal use. Ithink someone should buy the xmods 370z and throw everyperformance part for these cars at it. You can get ceramic ball bearings, full billet aluminum axles and frame/suspension pieces, a crabon fiber chasis, more powerfull motors, 4wd, and more. It's sick you could drop a grand easy in a little toy car.
