These O.E.M. brake rotors are made in Germany and have been precision slotted for maximum performance.  Directional slotting is the most effective way to improve rotor performance by removing brake dust from the surface, but avoids the potential for cracking associated with drilling. It also has the added benefit of improving the wet performance by quickly removing water from between the pad and rotor.  The gray paint used on the hub of these rotors has been matched to the original gray paint used by Porsche.

Each set consists of four directionally slotted rotors for RF/RR/LF/LR.
