Your brake system is by far the most important system when it comes to safety. Safeguard your brake system to protect yourself and passengers with premium brake system components or new brake kit. Beveled holes provide superior cooling under the most extreme conditions. The slots are rounded, which provides consistent contact between the rotor and pad while also sweeping away gas and dust. The result is a high performance rotor that enables harder and more precise braking, while also lowering temperatures by as much as 180 degrees.
