P/N: 31423305 Zimmermann Coat Z

Quality of Zimmermann rotors and drums starts with high end materials. Units are made out of non-machined castings containing flake graphite. The grey cast iron is then treated to other ingredients to stabilize its properties for durability and machining. Zimmermann compound is matched to each vehicle’s factory specifications analyzed from OE discs and drums and not limited to supplements like copper, molybdenum, titanium and carbon materials. Zimmermann has been offering its Coat Z anti-corrosion protection on rotors since 2008. This coating prevents the formation of rust at the hub for better longevity and improved lifetime appearance. The Coat Z rotors can be mounted right out of the box without ever removing the coating.
