From my understanding, they are a little thicker than stocks which is supposed to make them less likely to warp. Means longer time between servicing or replacing which will save you money. And everyone knows brembo is a reputable company and i plan on getting them soon... but things keep happening and keep me from having money to order them. Ahhh!! Anyway... i digress... get them.. i hear good things. But i don't think they will improve stopping distance if thats wat your asking... the surface area of the rotors are the same, but i'm sure they are more reliable.
