R1 Concepts 830-47070L DFC GeoPerf Drilled Slotted Performance Brake Rotor - Left

The R1 Concepts 830-47070L DFC GeoPerf is a premium drilled and slotted performance brake rotor designed to deliver enhanced stopping power and improved thermal management over standard OEM rotors. Engineered for drivers who demand more from their braking system, this left-side (driver's side) rotor combines precision machining with advanced venting geometry for consistent, fade-resistant performance.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes evacuate heat, gas, and debris while machined slots continuously sweep the brake pad surface for maximum bite and consistent contact
• GeoPerf Technology: R1 Concepts' proprietary geometric slot and drill pattern optimized for balanced performance and rotor longevity
• High-Carbon Grey Iron Construction: Premium metallurgy for superior heat absorption, reduced noise, and extended service life
• Zinc Dichromate Coating: Corrosion-resistant finish protects non-swept rotor surfaces from rust and surface oxidation
• Precision Balanced: Computer-balanced to minimize vibration and eliminate brake pedal pulsation
• Direct OEM Replacement: Bolt-on fitment with no modifications required
• Left Side (Driver's Side): Sold individually; verify application fitment for correct pairing

The R1 Concepts DFC GeoPerf drilled and slotted rotor is an ideal upgrade for performance street driving, towing, and spirited use where increased brake cooling and pad bite are essential. Pair with R1 Concepts performance brake pads for a complete, matched braking system upgrade.
