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

If you're heading to the track for a spirited driving day or competing in a spec racing series with your 2003-2008 BMW Z4, this PowerStop Track Day SPEC brake kit is built for that kind of action. This kit bundles together performance brake pads and rotors specifically chosen to handle the extreme demands of track use, taking the guesswork out of upgrading your rear brakes.

The Track Day SPEC pads are designed with a friction material that offers a good coefficient of friction even when cold, but really shines when they heat up, providing maximum performance during your track sessions. They're tested to resist fade and maintain a consistent pedal feel, even under hard braking. The included Autospecialty rotors are OE-style replacements that are dynamically mill-balanced for a smooth ride, and they fit your Z4 directly. This kit is considered a Stage 2 upgrade, meaning it's for drivers who are pushing their cars hard and need reliable stopping power lap after lap.

This kit includes the necessary abutment clips, tension clips, or pin bushings to help ensure a proper installation. As the official brake supplier for Radford Racing School, PowerStop has put these components through rigorous testing to ensure they perform when you need them most.
