Perfect fit, great performance for sporty road riding. Matches my red EBC Stuff Pads. The braking system is now quiet, even pad wear and performance on top of that! I don't do autocross so I can't confirm how it will handle higher heat loads. But slowing my score down from 80-0 is fantastic. These rotors work continuously in stop-and-go mode in combination with WOT. When they say "Silent Slot" they mean it! My old full length slotted rotors sounded so loud every time I pressed the brake pedal. Never. Very happy!
