As the only manufacturer in the spare parts market Zimmermann offers with
Formula Z 100.3363.75 a corrosponding disc to the  OE disc in quality, material and design.

But Zimmermann even goes a step further and offers a cross-drilled upgrade:
The version 100.3363.70 offers the cooler appearance when looking at the brake.

Both versions are equipped with aluminum hub and floating friction ring, this ensures a free radial expansion of the brake disc under heavy load.

Of course, both - the plain and the cross-drilled version - for the Audi A8 and Q5 vehicles have ECE approvals.

Your advantages:

• Substantial weight saving and therefore less unsprung mass means more braking comfort
• Floating mounting enables radial expansion of the brake disc under relatively heavy loads
• Cross-drilled version available
• Anti-corossion Coat Z
• 1:1 exchange of original disc possible
• Not subject to registration: ECE approved
• No conversion required for brake tuning
• More than 10 years of experience in manufacturing compound discs
