Zimmermann 460.4534.70 Formula Z Vented Perforated Two-Piece Floating Brake Disc

The Zimmermann 460.4534.70 is a Formula Z two-piece floating brake disc engineered for high-performance applications. Featuring a vented, perforated design with an anti-corrosion coating, this disc is purpose-built to deliver exceptional stopping power and thermal management under demanding mechanical and thermal loads.

The compound construction of the Formula Z disc combines a cast iron friction ring with an aluminum hat, resulting in significant weight savings and reduced unsprung mass. The floating mounting system allows the friction ring to expand radially under heavy braking loads, preventing distortion and dramatically increasing resistance to heat cracking and hot spots.

Key Specifications:

• Outer Diameter: 380 mm (14.96 in)
• Disc Thickness: 34 mm (1.34 in)
• Height: 69.4 mm (2.73 in)
• Bolt Hole Circle: 130 mm (5-hole pattern)
• Hub Bore (Centering Diameter): 98 mm
• Hole Pitch / Number: 7/5
• Construction: Vented, Perforated, Two-Piece Floating
• Finish: Coated (anti-corrosion)
• Not compatible with Porsche Ceramic Composite Brakes (PCCB)

Formula Z Advantages:

• Excellent deceleration with no distortion of the friction ring at high temperatures
• Substantial weight reduction and less unsprung mass versus solid OE-style discs
• Floating design enables radial expansion under heavy loads, preventing heat shielding
• Optimised ventilation channel geometry eliminates dangerous hot spots
• Anti-corrosion coating protects non-swept surfaces for a long service life

Manufactured by Otto Zimmermann GmbH in Sinsheim, Germany, the Formula Z line represents the pinnacle of Zimmermann's brake disc engineering — built on over 50 years of experience producing safety-critical brake components to OEM quality standards. This disc is sold individually.
