Power Stop 09-11 Audi A4 Front Evolution Drilled & Slotted Rotors - Pair Forced Induction>Boost Controllers We think like OE engineersPower Stop drilled and slotted rotors provide a bolt on upgrade for improved brake cooling and performance. Precision cross drilled for maximum cooling and maximum performance during extreme conditions; rounded slots sweep away gasses, dust, and moisture to keep a clean friction contact patch on the rotor surface. Silver zinc dichromate plating resists rust and corrosion. With a direct OE fit, there are no special modifications needed.
