Technical Details and Specifications

The Zimmermann 150.2911.20 disc brake rotor features an internally vented design that improves cooling during braking, reducing the risk of brake fade. The rotor’s high-carbon machining process increases its resistance to thermal cracking and wear, making it suitable for both daily driving and more demanding conditions. The coated surface adds an extra layer of protection against environmental factors, extending the rotor’s service life.

With an outer diameter of 370 mm and a thickness of 30 mm, this rotor meets the precise specifications required for BMW models such as the 320i xDrive, 335i GT xDrive, and 440i Gran Coupe. The 6/5 hole arrangement and 120 mm bolt hole circle ensure proper mounting, while the 79 mm hub bore diameter guarantees a secure fit on the wheel hub.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 320i, 328i, 335i, and 4 Series vehicles
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Improves braking performance and heat dissipation for safer driving
• Prevents corrosion-related rotor damage with coated surface
• Maintains braking efficiency by meeting minimum thickness requirements

Installation Notes and Tips

When installing the Zimmermann 150.2911.20 rotor, ensure the rotor surface is clean and free of debris before mounting. Verify the bolt hole circle and hub bore dimensions match the vehicle specifications. It is recommended to replace brake pads simultaneously to optimize braking performance. Proper torque settings should be applied to the mounting bolts to avoid rotor warping.

Quality Assurance and Warranty

Zimmermann rotors are manufactured to meet strict quality standards, including ABE certification (Kba 60787), ensuring compliance with German road safety regulations. The high-carbon machining and coated surface contribute to long-lasting performance. Warranty details should be confirmed with the point of purchase or manufacturer documentation.
