i have tarox discs, G88s in fact (40 grooves in each disc) they are the nuts. cost me a fair whack tho. Some people say they are over priced, other say you get what you pay for. make up your own mind.
i love the discs, but im not happy with my pads, DS2000s. breaking from say 90mph -> 60mph feels really good, tho at lower speeds feel really insecure. They dont call them fast road pads for nothing, they have just brought out a new brand that warm up alot quicker. I may try them next with some braided hoses.
