Zimmermann Formula F Brake Disc Rotor

The Zimmermann Formula F brake disc rotor line is a compound (2-piece) brake rotor designed as a replacement for original-equipment riveted compound discs. Each disc pairs a lightweight aluminum hub with a cast friction ring. This gives you a direct-fit replacement brake rotor that keeps the look and function of the factory design.

Key Features:

• Compound construction: An aluminum hub is friction-locked and riveted to a cast iron friction ring, in the style of OE compound discs.
• Reduced weight: Using an aluminum hub instead of a cast hub cuts weight by up to 15 percent. This lowers unsprung mass, which can help acceleration and handling.
• High-carbon friction ring: The high-carbon casting improves thermal conductivity and durability under heavy braking stress.
• Coat-Z corrosion protection: A heat-resistant aluminum lacquer coating helps prevent rust and keeps the disc looking good.
• ECE R90 approval: The range is approved to ECE R90 and is comparable to OE discs.

Zimmermann introduced the Formula F line in 2017 as a companion to its Formula Z compound discs. Choose the Formula F brake disc if you want OE-style compound rotor performance, lower weight and dependable stopping power for daily driving.
