Zimmermann 34-21-2-284-104 Formula Z Two-Piece Brake Disc 396x24mm

The Zimmermann 34-21-2-284-104 Formula Z brake disc is a high-performance two-piece composite rotor engineered for demanding driving conditions and high-performance applications. This advanced brake disc combines a gray cast iron friction ring with a lightweight aluminum hub, delivering exceptional thermal stability and reduced unsprung mass for improved vehicle dynamics.

Key Features:

• Two-piece floating design with aluminum hub and cast iron friction ring
• 396mm outer diameter x 24mm thickness for enhanced braking power
• Ventilated and cross-drilled design for superior heat dissipation
• Floating mounting allows radial expansion under high temperatures
• Reduces brake fade and thermal distortion during spirited driving
• Significant weight reduction compared to conventional one-piece rotors
• Prevents hot spots and heat cracks through optimized ventilation channels
• OEM part number 34212284104 for direct replacement

The Formula Z line represents Zimmermann's premium brake disc technology, specifically developed for sports cars and high-performance vehicles. The floating bearing design allows the friction ring to expand independently when heated, preventing warping and maintaining consistent braking performance even under extreme thermal loads. This makes the Formula Z ideal for track use, spirited driving, or any application requiring maximum braking performance and reliability.
