yeah, I wanted to say what our High boosted said...save your money on something that's not likely to make much difference unless the car is under special conditions, and spend on a decent set of rotors...which are the root of the problem anyway...

most cars these days(Performence category) that are anything near the weight of ours come standard with ATLEAST 354mm rotors (4+pot) assuming your in america you'd be silly not to atleast go to one of the cheaper 354mm kits as it's so DAMN CHEAP over there!!!
