R1 Concepts 830-54252L DFC GeoPerformance Drilled Slotted Brake Rotor - Left

The R1 Concepts 830-54252L is a DFC GeoPerformance Drilled and Slotted Brake Rotor engineered for superior stopping power, durability, and corrosion resistance. This is a directional left-side rotor featuring a premium GEOSPEC anti-corrosion coating and a cross-drilled and slotted braking surface for enhanced performance in both everyday and demanding driving conditions.

Key Features:

• Cross-Drilled & Slotted Surface: Drill holes dissipate heat build-up while slots improve pad bite and grip, delivering shorter stopping distances — especially in wet weather
• GEOSPEC Corrosion-Resistant Coating: Applied to the entire rotor including the hat and vane structure, providing long-lasting protection against rust and corrosion without any prep work needed at install
• Directional Left-Side Design: Rotor is specifically engineered as a left-hand (driver-side) directional unit for optimized airflow and braking performance
• OE-Grade Quality Control: Each rotor undergoes 100% electronic inspection across more than 20 attributes to confirm it meets or exceeds OEM specifications
• No Pre-Installation Cleaning Required: GEOSPEC finish is processed and shipped dry — bolt on and go
• DFC Part Number: 830-54252L (prefix 830 = Drilled + Slotted + Geomet coating)

The R1 Concepts DFC GeoPerformance series is the ideal upgrade for drivers seeking a high-performance replacement rotor that installs like OEM but delivers significantly improved thermal management and braking confidence. Sold individually.
