You may also wish to upgrade to the StopTech Brake Pads.

StopTech® Sport Rotors are direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer.


Slotting and/or cross-drilling helps wipe away the debris that forms between the pad and the disc, adds more bite, and can help the rear brakes to match the aesthetics of a front big brake kit. The rotor finish helps prevent glazing of the pads and improves wet and dry braking performance.


Additionally, StopTech® Sport Rotors feature a durable black e-coating on the non-swept areas of the rotor to prevent corrosion.


All StopTech® Sport Rotors are also available cryogenically treated to better align the molecular structure of the disc for enhanced durability and longer life. When so treated, they are known as StopTech Cryo® rotors.
