Does anyone have 4 piston front brakes? I belive they come from a 3000GT or somthing, basicly they are a big, so the question is is fitting them to a GSR possible, I kno they will most likely bolt on and a brake hose can be fitted up, I have 17" wheels so that should'nt be a problem, but will the master cylinder cope? even if upgraded to an EVO one? or would you have to spend a shitload on a custom one of some description? Rotors could also be a problem as they are bigger than EVO ones...
