Product Details

This DFC Brake Rotor - Drilled and Slotted - Black is part of Dynamite Friction’s rotor line focused on direct-fit brake service for BMW performance platforms. The directional braking surface is engineered for front right placement and is listed across multiple BMW chassis and brake package combinations, including M Sport Brakes, M Sport Package, standard brake setups, aluminum hat rotors, and full cast rotor configurations where specified. If you are replacing a worn BMW front rotor and need the correct drilled and slotted rotor profile, 633-31108R matches the application details shown in the fitment data.

This part cross-references OE-style rotor applications for the same BMW front right fitments listed here.

What It Helps Address

• Brake pulsation from a worn or uneven front rotor surface
• Reduced braking consistency on BMW performance brake packages
• Surface corrosion on exposed rotor hats
• Brake fade concerns during repeated stops
• Noise or vibration caused by rotor wear beyond service limits

Installation Notes and Tips

Install on the front right position only, and verify rotor diameter, bolt circle, center hole diameter, and brake package details before ordering. This rotor is listed for BMW applications with M Sport Brakes and related performance brake configurations, so confirm your vehicle’s original rotor style and caliper setup against the fitment notes. Always inspect pads, calipers, and hub surfaces during rotor replacement, and follow the vehicle manufacturer’s service procedures for torque and bedding.

Quality Assurance

Dynamite Friction identifies this rotor with a rust resistant coating and zinc black hat finish for added corrosion protection in service. The directional drilled and slotted design, vented construction, and application-specific dimensions support consistent fitment for the listed BMW front right brake applications.
