Cross-Drilled & Slotted Brake Rotors - Front - E32, E34 540i (pair)

Slotting a rotor helps to release gases that build up between the rotor surface and an out-gassing brake pad. Without an escape, this thin layer of gas will cause a delay until the pad cuts through gas layer. The slots in our rotors allow the gases to escape giving better braking performance. Cross-drilling a rotor is a way to improve initial pad bite. With the additional leading edges at each hole, the pad is able to grab the rotor just a little bit harder.

By combining both Cross-drilling and slotting, these rotors combine the best of both worlds. Fewer holes mean longer pad life with little penalty in the way of initial pad bite.

These rotors feature a unique black electro-coating that is designed to prevent corrosion. Each rotor is e-coated then double-ground and balanced to ensure an even surface with no vibration. The e-coating is the best anti-corrosion protection currently available in replacement rotors. Most aftermarket rotors are not coated, allowing surface rust to form right away, which is unattractive when brakes can be seen through your wheels.
