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.

Product Features:

• Coat-Z protective anti-corrosion coating
• Better wet braking performance by permanent expulsion of brake dust and water
• Sporty look
• Because of the anti-corrosion protection Coat Z better finish – especially of the hub and the outer diameter
• Noticeable improvement in the braking power of your car
• Prevention of brake fade
• Countersinking of holes doubles up as wear indicator
• 1:1 exchange of original disc possible
• No additional adaption necessary
• Not subject to registration: general ABE certification supplied with disc

WBR Run True Technology Metallurgic-Gray (MG) Finished Rotors All World Brake Resources (WBR) brake rotors with Run-True technology are manufactured to match the exact OE fit, OE construction, and precision finishing to ensure quick and easy installation, as well as trouble-free functionality for the life of the rotor. The Metallurgic-Gray coating is applied to all outward non-friction surfaces including in the gap between the plates covering the cooling vanes and cured through an oven drying process. The Gray coating provides an effective anti-rust protection to help maintain a clean appearance. The coating used for WBR is also similar to the OE color used by many OE car makes. WBR Brake Rotors with Run-True Technology have ultra tight tolerances that provide the finest braking experience, from break in throughout the life of the rotor, reducing the chance of warping even under extreme braking temperatures. The coated brake disc provides a protective water based coating that prevents rust and corrosion, extended rotor life and improved visual appearance. WBR Brake Rotors are manufactured to meet or exceed the original equipment manufacturer specification for durability, fit, and function.

Product Features:

• High metallurgical and machining standard to improve stopping distances
• Produced to match OE design fitment – G 3000 gray iron
• Mill balanced
• TS16949 certified
• Non-directional finish provides smooth vibration free performance
• No need for machining prior to installation
• Durable Metallurgic-Gray finish to all outward non-friction surfaces
• Metallurgic-Gray anti-rust protection to help maintain a clean appearance
• Compatible with NAO, Ceramic and Semi-Met pad compounds for reduced noise
• Designed to minimize brake fade and extend pad and rotor life
• 24/24 Warranty – limited warranty against defects in material and workmanship Technical Service Bulletins

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.
