StopTech 2008-2012 Audi S4 Slotted & Drilled Left Front Brake Rotor

StopTech Sport Rotors are premium quality replacement brake rotors featuring a signature "short slot" design. This design improves brake system performance by wiping away debris from used friction material, preventing pad glazing, and keeping fresh pad material exposed to the rotor surface. The edges sweeping the pad slightly increase the effective coefficient of friction or "bite," amplifying brake system response to pedal input. Slotted rotors also improve initial brake response under wet conditions by providing an escape path for water. These rotors are e-coated with advanced metallurgy, including added Molybdenum and Chromium, to greatly reduce pad squeal and resist rotor cracking, especially with higher friction, European-style brake pad compounds.
