Dynamic Friction 631-42046R DFC Drilled Slotted Brake Rotor

The Dynamic Friction Company (DFC) 631-42046R is a premium drilled and slotted brake rotor engineered to deliver superior stopping performance and extended service life. Combining the benefits of cross-drilled holes and precision-machined slots, this rotor is designed to outperform standard OE-style solid rotors in both everyday driving and demanding conditions.

Key Features:

• Cross-Drilled Holes: Reduce rotor weight and allow heat, gas, and moisture to escape from the braking surface, helping to prevent brake fade during repeated or heavy stops
• Precision-Machined Slots: Continuously sweep the brake pad surface to remove debris, dust, and gas buildup, maintaining a clean contact patch and consistent bite throughout pad life
• Premium G3000 Castings: Manufactured from high-grade G3000 grey iron for durability, consistent performance, and compatibility with a wide range of brake pad compounds
• Zinc Dichromate Coating: Full-coverage corrosion-resistant coating protects non-braking surfaces from rust and extends the cosmetic life of the rotor
• OE-Matched Geometry: Engineered to OEM specifications for a precise, direct-fit installation with no modifications required
• Balanced and Tested: Each rotor is precision balanced and tested for runout and thickness variation to ensure smooth, vibration-free braking

The DFC 631-42046R is an excellent upgrade for drivers seeking improved thermal management and braking consistency over a stock replacement rotor. It is compatible with most OE and performance brake pad compounds and installs using standard hand tools.
