PowerStop is on a mission to deliver an easy way for any driver to upgrade their brakes - no matter where or how they use their vehicle. The difference between the checkered flag and 2nd place is measured in milliseconds. While there are many ways to shave time off your fastest lap, a brake upgrade is one of the best. For weekend track days and HPDE, our Track Day High-Performance Brake Kit can take the heat. This kit comes complete with PowerStop Track Day brake pads and Autospecialty rotors, taking the guesswork out of purchasing brakes for track use. As the official brake supplier of Bondurant Racing School, Track Day brake pads are data-driven and tested to provide extreme fade resistance, low thermal conductivity, and consistent pedal feel. The Autospecialty brake rotors are 100% dynamic mill-balanced and provide a direct fit solution for your vehicle. Whether you’re a seasoned pro or just getting some weekend time on the grid, have confidence and control at every corner with PowerStop Track Day High-Performance Brake Kit.
