Zimmermann 150.2973.70 Formula Z Floating Brake Disc Rotor

The Zimmermann 150.2973.70 is a Formula Z floating brake disc engineered by Otto Zimmermann GmbH, a German manufacturer with over 50 years of experience producing precision brake components for the automotive industry. The Formula Z line represents Zimmermann's highest-performance floating rotor design, developed to deliver consistent, reliable braking under demanding mechanical and thermal conditions.

Key Features:

• Floating Disc Design: The floating mounting system allows radial expansion of the brake rotor under heavy loads, preventing distortion and significantly increasing resistance to heat cracks
• Coat Z Anti-Corrosion Treatment: The complete rotor surface is treated with Zimmermann's proprietary Coat Z coating for outstanding corrosion resistance and an attractive finished appearance
• High-Carbon Grey Cast Iron Construction: Manufactured from flake graphite grey cast iron with carefully matched alloy ingredients — including copper, molybdenum, titanium, and carbon — formulated to mirror OE material specifications
• Accommodates Tuned Applications: The compound rotor design accommodates the increased demands of engine-tuned vehicles and optimized chassis structures
• OE-Equivalent Quality: Meets the equivalent-quality spare parts standard as defined by motor vehicle block exemption regulation KFZ-GVO (EU) No. 330/2010, on par with original parts
• Certified: ABE certification or ECE approval documentation supplied with the rotor — no separate registration required
• Sold Individually: This listing is for one (1) brake disc; two are required per axle

The Zimmermann Formula Z brake disc is an excellent alternative to OE brake rotors and a premium solution for performance and enthusiast applications. Otto Zimmermann GmbH conducts ongoing inertia dynamometer and real-world driving tests in partnership with TÜV NORD to validate product quality and longevity.
