Product Details

The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on application-specific rotor construction for BMW 5 Series and 6 Series platforms. This rotor uses a directional, slotted and drilled braking surface to match the front right position on supported vehicles, including BMW 640i, BMW 640i xDrive, BMW 535i, BMW 535d, and BMW ActiveHybrid 5 models. The 348 mm diameter, vented design, and 5-lug 120 mm bolt pattern align with the original-style fitment requirements listed for these applications. Part number 631-31097R is a direct reference for shoppers searching by rotor size, position, or vehicle fitment.

Common Brake Issues This Rotor Can Address

• Front brake rotor wear that has reached discard thickness limits
• Brake pulsation caused by uneven rotor surface condition
• Corrosion on the rotor hat or exposed metal surfaces
• Reduced braking consistency from a worn or heat-affected front rotor
• Noise or surface irregularity associated with an aging disc brake rotor

Installation Notes and Tips

Verify the front right position, rotor diameter, bolt circle, center hole diameter, and thickness before installation. This rotor is listed for BMW models that may use either aluminum hat or full cast rotor configurations, so confirm the brake package on the vehicle before ordering. Inspect the brake pads, caliper condition, and hub surface during replacement, and follow the vehicle manufacturer’s service procedure for torque and bedding.

Quality Assurance

Dynamite Friction identifies this rotor with a rust resistant coating and zinc silver hat finish for added surface protection. The part is built to the listed dimensional specifications for the supported BMW applications, including 2011-2019 BMW 535i, 535d, 640i, and ActiveHybrid 5 front right fitments.
