Power Slot 09-10 Audi A4/A4 Quattro / 08-10 A5 / 10 S4 Front Left Drilled & Slotted Rotor Stoptech 127.33123L

StopTech Drilled and Slotted Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique cross-drilling and slotting aids with heat and brake dust dispersal, prevents glazing of the pads, adds bite and improves wet and dry braking performance. Built to last, the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation, better crack resistance and increased performance.
