Technical Details and Specifications

The Zimmermann 100.3382.70 disc brake rotor features a two-piece design that separates the braking surface from the aluminum hub. This alu hub floating construction reduces unsprung weight and improves heat dissipation, which is critical for high-performance vehicles like the Audi RS7. The rotor’s high-carbon machining enhances wear resistance and braking consistency, while the coated surface protects against corrosion and environmental damage.

With an outer diameter of 390 mm and a thickness of 36 mm, this rotor meets the precise fitment requirements for the Audi RS7. The bolt hole circle diameter of 112 mm and a 6/5 hole arrangement ensure secure mounting. The hub bore diameter of 68 mm and a height of 52.4 mm provide proper alignment and stability during operation. The rotor also carries an ECE R90 inspection tag, confirming it meets European safety and quality standards.

Applications and Problem Solving

• Replacement for worn or warped brake rotors on Audi RS7
• Improves braking performance and heat management under high load
• Addresses brake judder caused by uneven rotor surfaces
• Prevents corrosion-related rotor degradation with coated surface
• Ensures compliance with safety regulations through ECE R90 approval

Installation Notes and Tips

• Verify compatibility with Audi RS7 before installation
• Ensure rotor thickness meets or exceeds minimum thickness of 34.4 mm
• Use proper torque specifications for the 6/5 bolt hole arrangement
• Inspect hub bore and mounting surfaces for cleanliness and damage
• Follow manufacturer guidelines for bedding-in new rotors and pads

Quality Assurance and Warranty

Zimmermann disc brake rotors are manufactured to meet strict quality standards, including ECE R90 certification, which guarantees performance and safety compliance. The high-carbon machining and alu hub floating design contribute to long service life and reliable braking. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
