Power Stop 03-05 BMW Z4 Rear Track Day Brake Kit

If you're heading out for weekend track days or HPDE events in your 2003-2005 BMW Z4, upgrading your brakes is a smart move. This Track Day High-Performance Brake Kit from PowerStop is built to handle the extra heat and stress that comes with spirited driving on the track. It takes the guesswork out of choosing parts by bundling performance-oriented rotors and pads specifically for track use.

The kit features Autospecialty rotors that are mill-balanced for a smooth ride and are designed as a direct fit for your Z4. Paired with these are PowerStop's Track Day brake pads, which are formulated with a carbon-fiber and metallic compound. These pads are tested to offer extreme fade resistance and maintain consistent pedal feel, even when they get hot. They also provide a good coefficient of friction whether the brakes are cold or at operating temperature, giving you reliable stopping power when you need it most.

This is considered a Stage 1 kit, suitable for drivers getting started with track days. It includes necessary hardware like abutment clips and tension clips to help ensure a proper installation. As the official brake supplier for Radford Racing School, PowerStop has data-driven testing behind these components, aiming to give you confidence and control on the track.
