Power Stop 03-08 BMW Z4 Rear Track Day Brake Kit

If you're taking your 2003-2008 BMW Z4 out for weekend track days or HPDE events, upgrading your brakes is one of the most effective ways to improve performance and confidence. This Track Day High-Performance Brake Kit from PowerStop is designed specifically for those demanding situations. It bundles together the necessary components to give you a solid foundation for track-focused braking.

This kit includes PowerStop Track Day brake pads and Autospecialty rotors. The pads are formulated with a carbon-fiber and metallic compound that offers a high coefficient of friction, meaning they grip well whether cold or hot, and maintain that grip even as temperatures climb. They're built for extreme fade resistance and low thermal conductivity, helping to keep pedal feel consistent lap after lap. The included Autospecialty rotors are OE-style replacements, mill-balanced for a smooth ride, and ensure a direct fit onto your Z4.

This is considered a Stage 1 kit, suitable for drivers beginning to explore track days. It's designed to work well with street tires. You'll find that the included abutment clips, tension clips, or pin bushings help ensure proper installation of the brake pads.
