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 slotted and drilled 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. The slots on these rotors will clear away the debris and give your brakes a clean and powerful stop every time. The cross drilled holes help to dissipate heat and water when it is raining out. With this combination these StopTech dilled and slotted provide the ultimate in stopping power. 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 Drilled & Slotted Rotors.
Please note the Audi A4/S4 StopTech Drilled/Slotted Rotors are sold in pairs.
