1976 Porsche 912 Front Brake Rotors

The Zimmermann Sport Brake Disc was developed as a result of experience of brake discs in series-production vehicles in connection with racing. The brake system is optimized by combining high-quality cast materials with a slotted or cross-drilled braking surface. Coat-Z Protective Coating – The Zimmermann Coat-Z brake disc provides a protective coating that prevents rust and corrosion, extended rotor life and improved visual appearance. To improve the rust protection during storage and usage, Otto Zimmermann GmbH implements this new Coat-Z technology step by step in its production range. Beside the still optimum function of the brake disc, this coating ensures a consistent attractive appearance. Material quality / high carbon – Zimmermann brake discs are usually made of cast iron (with flake graphite) of different qualities; they correspond to the material used for the original spare parts. Therefore, the utilization of such materials (referred to as High Carbon by the competition) has always been a matter of course for Otto Zimmermann.

Bosch rotors utilize innovative materials that ensure the very highest quality – and prevent brake judder, noise, vibration and harshness. Bosch QuietCast Premium Disc Brake Rotors utilize vehicle specific castings. The heat flow casting process produces superior G3000, GG20, GG15 and HC (high carbon) casting. Bosch castings provide strength and durability not found in competitive product. While competitors may provide a low cost product which helps save money, their castings can crack and provide poor durability. Bosch QuietCast provides consistent, safe and long lasting performance. Alutherm 80 Coating – Bi-metal aluminum and zinc clean-look coating/Alutherm 80 extends the life of the rotor and provides a clean look for today’s open wheels
