Key Features
- Vented disc brake rotor for improved heat management during repeated stops.
- Alloyed high-carbon machining for stable rotor behavior under load.
- Coated surface helps resist corrosion on exposed braking surfaces.
- Aluminium hub floating construction supports precise rotor alignment.
- ECE R90 approved for replacement brake applications.
Detailed Description
Zimmermann 150.2971.70 is a vented disc brake rotor with a 400 mm outer diameter, 36 mm thickness, and 34.4 mm minimum thickness. The rotor uses a 120 mm bolt hole circle, 79 mm centering diameter, and a 10/5 hole arrangement, with a 65 mm height. Its alloyed/high-carbon machining and coated finish are specified for durability and consistent service characteristics. This part number, 150.2971.70, is listed for the front left position on the BMW M2.
This rotor is paired with 150.2972.70 and cross-references Monroe Shocks & Struts (e.g., 150.2971.20, 150.2971.52) for the same application.
Common Replacement Reasons
- Brake pulsation from rotor wear or thickness variation.
- Reduced braking consistency during repeated high-load stops.
- Corrosion on the rotor surface affecting service condition.
- Rotor scoring, cracking, or heat-related damage.
- Need for a direct replacement rotor for BMW M2 brake service.
Installation Notes
Verify rotor dimensions, hub fitment, and mounting pattern before installation. Confirm the front left application on the BMW M2 and compare the existing rotor to part number 150.2971.70 before service. Follow standard brake service procedures and inspect related brake components during replacement.
Quality Assurance
Zimmermann identifies this rotor as ECE R90 approved, indicating compliance with the applicable replacement brake standard for this application.
