porsche986spyder:

check your measurements. a rotor that's 1.25" in diameter larger than stock will hit the caliper. even if it COULD fit, your pads wouldn't sweep the outermost portion of the rotor. also, the largest sports car rotors i'm aware of are 15.7" / 400mm diameter. a 17" / 18" disk w/ caliper won't fit inside the wheels. not to mention the inertia starts to really work against you when you go too big on rotors.
I give up, I don't want this to turn into a long arguement. I just know that my aftermarket ones are definatley larger than the stock ones. When I mentioned 17-18 inch massive rotors I was not speaking of ones made for our cars, but just that there are some out there for other cars.
