Rear Rotor Set (330x20mm) - BMW / G20 / 330e / 330i | 34206883979-ZIM-KT

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

Zimmermann GmbH is a global leader in vehicle brake technologies and is an original equipment manufacturer of high quality brake discs and components. Zimmermann products are engineered to OE specifications and are inertia-dynamometer tested to guarantee superior quality.
