Dynamic Friction 631-20044L DFC Drilled Slotted Brake Rotor - Left Rear

The Dynamic Friction Company (DFC) 631-20044L is a precision-engineered drilled and slotted brake rotor designed as a direct-fit replacement for the left rear wheel position. Built to OEM dimensions for accurate fitment, this rotor delivers enhanced braking performance over standard smooth rotors, making it an ideal upgrade for drivers seeking improved stopping power and thermal management.

Drilled & Slotted Design Benefits:

• Cross-drilled holes dissipate heat rapidly, reducing brake fade during demanding driving conditions
• Machined slots channel away gases, dust, and debris from the pad surface for consistent bite and improved pad bite-in
• Vented construction promotes airflow between rotor faces to maintain optimal operating temperatures
• Corrosion-resistant coating on non-friction surfaces helps prevent rust and extends rotor service life
• Precision-balanced to minimize vibration, pulsation, and steering wheel shimmy
• Direct OE replacement — no drilling, cutting, or modifications required for installation

Dynamic Friction Company rotors are manufactured to strict dimensional tolerances, ensuring proper hat height, rotor thickness variation (RTV), and lateral runout (LRO) within OEM specifications. The 631-20044L pairs seamlessly with DFC brake pads or quality OEM-equivalent pads for a complete brake system upgrade.
