Description Sold as Pair. Since 2008 Zimmermann is offering almost 400 Standard and almost 400 Sports Brake Discs in a coated version named Coat Z 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.

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. Features and Benefits Coat-Z protective anti-corrosion coating No formation of rust at the hub and herewith improved visual appearance Immediate functional capability without removal of the coating before mounting Excellent deceleration action and no distortion of friction ring at high temperatures.

Substantial weight saving and therefore less unsprung mass Floating mounting enables radial expansion of the brake disc under relatively heavy loads, thus preventing shielding and increasing resistance to heat cracks Hot spots prevented by optimized design of ventilation channels 1:1 exchange of original disc possible Not subject to registration: general ABE certification supplied with disc No conversion required for brake tuning.
