Description

The Zimmermann Sport brake disc COAT Z for the rear axle was specifically developed to noticeably improve the braking performance of classic Porsche models. Thanks to the internally vented design and precisely positioned cross-drilling, heat is efficiently dissipated, ensuring consistent braking performance – even during dynamic driving.

The coating (COAT Z) permanently protects the braking system from corrosion and provides a clean, high-quality look, especially on hubs and outer edges. The perforated surface improves braking performance in wet conditions, minimizes brake fade, and supports the self-cleaning of the pads.

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