Zimmermann Formula F 34216860925, 150294632 Disc Brake Rotor; Rear – BMW | 34208853554

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. Added to the Zimmermann line in 2017, the Formula F rotor is a compound rotor design to answer the OEM requirement for riveted compound brake discs. With an aluminum hub friction-lock riveted to a cast iron friction ring, it offers enhanced thermal conductivity and reduced weight for better performance.
