that just looks plain SICK! i really want one now lol darn u! but id say for brakes, i have a mini inferno and it has a center diff with gears and nothing more, so no oil or anything and when i jam the gas it unloads, but jam the brakes and all 4 wheels would be stopping... id think the same here, past that just use heavier wt oil if it does happen lol.....but what other cars could u do this for? id want a truggy like this, lol every time i look at it im like I NEED THAT!
