Description

Power Stop is on a mission to deliver an easy and affordable way for any driver to upgrade their brakes--no matter where or how they use their vehicle.

Power Stop Evolution drilled and slotted rotors provide a bolt-on upgrade for improved brake cooling and performance on your car, truck, or SUV. They are precision cross-drilled for maximum cooling and maximum performance during extreme conditions; rounded slots sweep away gas, debris, and moisture to keep a clean friction contact patch on the rotor surface providing smooth, safe braking. Rotors without an integrated bearing are covered in silver zinc dichromate plating resists rust and corrosion. With the direct OE fit of Power Stop Evolution drilled and slotted rotors, upgrading the looks and stopping power of your vehicle has never been easier.
