ok, well if you dont tihnk the stock 4-tec rolls better than you than what is your car? cause if its some modified car with a new motor other than the stock motor you bought it with then you need to get a clue, stock 4-tec vs. ur modified car,modified cars usually beat stock cars easily because well their modified... now if oyu take a modified 4-tec vs. ur modified car, fairer match. But if your just saying that there is no way that a stock traxxas nitro 4-tec can beat you modified car or even stock car then you have never had a traxxas or raced one...

With a properly shimmed driveline along with complete CV shafts throughout and a one way ball diff in the front and ceramic ball berings throughout, I have a hard time believing the stock 4-teck rolls better than mine. And no I've never bent a drive shaft, must be cause there 4mm thick!
