Your stock brake rotors were never designed for race or heavy braking use. With abuse like this they will eventually warp or even crack. These StopTech power slot slotted rotors will not only stand up against any abuse you can put them through, but also give you more responsive stopping power. On a normal rotor, debris gets trapped in between the pad and the rotor; reducing stopping power and scratching the rotor. These StopTech Slotted Rotors clear away the debris, leaving you with a fresh pad surface every time. The StopTech Slotted Replacement rotors simply replacing your existing rotors and do not require any modifications to fit. Improve your braking power and your brake appearance with these StopTech Slotted Rotors.
Please note the Audi A4/S4 StopTech Power Slot Slotted Rotors are sold in pairs.
