Discover top-rated parts for your 2025 Audi S4.

Zimmermann – Coated Brake Disc – Rust & Corrosion Protection, Extended Life (Part No.N10001318595ZIC)

Coated Brake Disc - Rust & Corrosion Protection, Extended Life

from

$162.35
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.

Product Features:
  • 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
