Overview
The Zimmermann Formula Z disc brake rotor is built for high mechanical and thermal load, with a two-piece construction and floating aluminum hub design. It is a direct fit for select Audi RS6 rear brake applications and is engineered to handle demanding braking conditions with stable performance.
Part number 100.3370.70 is coated for corrosion resistance and uses high-carbon machining to support heat management. The floating mounting design allows radial expansion under load, helping reduce heat cracking and maintaining braking consistency.
Key Features
- Two-piece disc brake rotor with floating aluminum hub construction
- High-carbon machining for demanding braking conditions
- Coated surface for improved corrosion resistance
- Designed for stable braking under high thermal load
- ABE-certified rotor supplied with ECE note
Detailed Description
Zimmermann Formula Z rotor 100.3370.70 is a performance-oriented brake disc designed for applications that place greater stress on the braking system. The floating mounting allows the disc to expand radially during heavy use, which helps reduce shielding and improves resistance to heat cracks. Its coated finish also supports long-term appearance and corrosion protection.
This rotor is a fitment-specific replacement for the Audi RS6 rear brake application listed below. The part number 100.3370.70 is also referenced in interchange data for related OE-style applications, including 4F0 615 601 H and Davico Mfg 18550.
What It Helps Address
- Brake fade during repeated high-load stops
- Heat cracking from elevated rotor temperatures
- Corrosion on exposed rotor surfaces
- Reduced braking consistency under demanding use
- Fitment issues when replacing the specified rear rotor application
Installation Notes
Fits 2010 Audi RS6, rear, for PR number 1KJ. Verify rotor dimensions, hub bore, bolt circle, and minimum thickness before installation. Confirm the brake system code and application details against the vehicle before ordering. Part number 100.3370.70 should be matched to the listed fitment and brake specification.
Quality Assurance
Zimmermann supplies this rotor with ABE certification and an ECE note, indicating regulatory documentation is included with the part. The Formula Z line is engineered for high-load braking applications and uses a coated surface to support corrosion resistance.
