R1 CONCEPTS GEOMET SERIES BRAKE ROTORS | DRILLED | 718 CAYMAN/BOXTER | 2017-2019
 
Crossed-Drilled rotors reduce the heat that builds on the rotor by up to 105°F. Cross-drilled rotors are also chamfered, which reduces the potential for cracking
 
Break in Procedure
Please be advised that when you first receive the rotors, they are completely covered with the GEOMET® coating. During the initial embedding process, the GEOMET® coating on the braking surface, the area where the pads come in contact with the rotors will wear off, leaving only the hub an inner vane structure coated.
