We are three friends and we all have RS4 3 18SS. Everything stock, minus the aluminum pipes. I've drag raced a Traxxas 4-tec which is belt and I won. My friend raced for 20 minutes with five serpents, which are belt, and came second, which is pretty good!

I'm sorry, but for me, shafts and belts, are just a way to transfer power to the wheels. And shafts are almost unbreakable.
