Key Features

• High carbon alloy metallurgy helps reduce pad squeal with higher-friction European brake pad compounds
• Molybdenum and chromium content improves resistance to cracking during repeated stops and higher-load use
• Increased carbon and chromium content helps resist oxidation
• Vented rotor design supports heat management during braking
• Smooth surface and coated hat finish for a clean, service-ready appearance
• Fits BMW 535d, 535i, 535i xDrive, 640i, 640i Gran Coupe, 640i xDrive, 640i xDrive Gran Coupe, and ActiveHybrid 5 front brake applications

Product Details
