Description

The Zimmermann COAT Z sport brake disc for the rear axle was specially developed to noticeably improve the braking performance of classic Porsche models. Thanks to its internally ventilated design and precisely positioned transverse bores, heat is efficiently dissipated and consistent braking performance is ensured – even under dynamic driving conditions.

The coating (COAT Z) provides lasting protection for the brake system against corrosion and ensures a clean, high-quality look, especially on hubs and outer edges. The perforated surface improves braking performance in wet conditions, minimizes brake fade, and promotes the self-cleaning of the pads.

The disc can be exchanged 1:1 for the original brake disc without any additional modifications and fits both the left and right sides of the vehicle.
