StopTech Power Slot & SportStop rotors are a direct replacement upgrade designed to fit your factory brake system and stock calipers. The unique slotted or cross-drilled surface helps wipe away debris that can form between the pad and the disc, provides more initial pad bite, improves cooling, and will add a sporty track inspired aesthetic to any ride. All Power Slot and SportStop rotors feature a friction surface coating to prevent glazing as well as a durable black e-coating on the center sections to prevent corrosion and enhance the look of aftermarket wheels. StopTech Power Slot & SportStop rotors are manufactured to the highest tolerances of safety and quality. Designed using only the highest quality OEM replacement blanks, StopTech rotors are guaranteed to have a top shelf fit and finish.
