Power 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.
