R1 Concepts 830-54269L DFC GeoPerf Drilled Slotted Performance Brake Rotor - Left

The R1 Concepts 830-54269L DFC GeoPerf Drilled & Slotted Brake Rotor is a high-performance direct-fit replacement rotor engineered for drivers who demand superior stopping power and fade resistance. This left-side rotor features a precision-machined disc with a combination of drilled holes and milled slots to maximize heat dissipation, reduce brake fade, and improve wet-weather braking performance.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor mass and allow hot gases and debris to escape, while slots continuously clean and deglaze brake pad surfaces for consistent bite
• DFC GeoPerf Series: R1 Concepts' geometrically optimized performance rotor line, balancing street drivability with enhanced performance characteristics
• G3000 Grade Metallurgy: Cast from high-carbon G3000 spec iron for consistent density, reduced thermal cracking risk, and longer rotor life
• Electrostatic Zinc Coating: Protective anti-rust coating on the hat and non-swept surfaces to prevent corrosion during storage and early service life
• Precision Balanced: CNC-machined to tight tolerances for a vibration-free, pedal-pulsation-free installation
• Direct OE Replacement: Engineered as a direct bolt-on replacement — no modification or machining required
• Left Side (Driver Side): Sold individually; this listing is for the left/driver-side rotor only

The R1 Concepts DFC GeoPerf rotor is an ideal upgrade for performance-minded drivers seeking improved thermal management over standard blank rotors, whether for spirited street driving or light track use. Compatible with standard OE brake pads or upgraded performance pads.
