• UV coating protects the disc and braking plate surfaces
• High carbon cast iron construction where applicable for quieter operation
• Solid rotor design with 324 mm outside diameter
• 5-hole bolt pattern with 75 mm centering diameter
• Minimum thickness marking location for service reference
• Fixing screw kit included with necessary hardware
• Part number: 08.5580.11

Product Details

This Brembo rotor is engineered to meet or exceed OEM specifications for rear brake service on BMW 740i, BMW 740iL, BMW 840Ci, BMW 850Ci, BMW 850CSi, and BMW 850i applications. The UV-coated finish helps protect exposed surfaces from rust, while the solid rotor format supports stable braking performance. Brembo also recommends replacing rotors and pads together to restore braking performance, and pairing this rotor with Brembo NAO/Ceramic or Low Met brake pad formulations. This part cross-references Bosch 96347 for the same application. Part number 08.5580.11 is also referenced in OE-style replacement catalogs for select BMW rear brake systems.

Common Brake Issues This Rotor Can Address

• Brake pulsation from worn or uneven rotor surfaces
• Noise caused by rotor wear or surface corrosion
• Reduced braking consistency from rotor thickness loss
• Rust buildup on exposed braking surfaces
• Vibration during rear brake application

Installation Notes

Verify rotor dimensions, bolt pattern, and minimum thickness before installation. Clean the hub mounting surface thoroughly to help prevent runout-related issues. Replace brake pads at the same time when restoring braking performance, and follow the vehicle manufacturer’s torque specification of 120 Nm where applicable. Confirm rear fitment for your BMW 740i, 740iL, 840Ci, 850Ci, 850CSi, or 850i before ordering.

Quality Assurance

Brembo develops this UV Coated rotor as an OE-equivalent replacement with attention to corrosion protection, dimensional accuracy, and serviceability. Intelligent marking locations identify the part number and minimum thickness for easier inspection during brake maintenance.
