Dynamic Friction 631-52027L DFC Drilled & Slotted Disc Brake Rotor - Left

The Dynamic Friction Company (DFC) 631-52027L is a premium performance disc brake rotor featuring a cross-drilled and slotted surface design engineered for improved braking performance over standard blank rotors. This is a left-side (driver's side) directional rotor built to OEM form, fit, and function specifications.

Key Features:

• Premium G3000/G11H18 Cast Iron Construction — Engineered for superior strength, stability, and long-lasting durability
• Cross-Drilled Holes — Reduce heat buildup on the rotor surface; chamfered holes minimize the risk of cracking under repeated thermal stress
• Machined Slots — Clear brake dust, road debris, and gases from the pad-to-rotor interface, preventing pad glazing and improving bite
• Zinc Silver Hat Finish — Rust-resistant zinc plating on the rotor hub, vents, and edge for long-term corrosion protection
• 100% Precision Mill-Balanced — Ensures smooth, vibration-free stopping at any speed
• CNC-Machined to Tight Tolerances — Each rotor passes a 100% electronic inspection station verifying over 20 attributes to confirm OE specification compliance
• OE Vane Configuration — Vented design maintains proper heat dissipation consistent with original equipment design
• Direct OEM Replacement — No modifications required; installs straight from the box

DFC's drilled and slotted rotors are ideal for performance street driving where enhanced wet-weather grip, reduced fade, and shorter stopping distances are priorities. The combination of cross-drilling and slotting delivers improved braking response compared to standard smooth rotors, while the zinc-coated finish helps protect the rotor between brake applications.
