R1 Concepts 830-65013L DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-65013L is a premium DFC GeoPerf Series drilled and slotted brake rotor engineered for drivers who demand superior stopping power and consistent fade-free performance. This left-side rotor combines two proven performance enhancement techniques — cross-drilling and slotting — into a single, high-quality disc designed to outperform OEM rotors in both daily driving and spirited conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce unsprung weight and improve heat dissipation, while geometric slots continuously sweep the brake pad surface to maintain a clean, consistent contact patch
• GeoPerf Geometry: R1 Concepts' proprietary slot geometry is engineered to maximize pad bite and minimize brake fade under repeated, hard stops
• G3000 Grade Cast Iron: Manufactured from high-carbon G3000 grade iron for optimal strength, durability, and thermal stability
• Zinc Dichromate Coating: Non-braking surfaces feature a zinc dichromate coating to resist corrosion and maintain a clean, finished appearance
• OEM-Grade Precision Machined: Meets or exceeds OEM dimensional tolerances for direct bolt-on fitment — no modifications required
• Left-Side Fitment: Designed specifically for the left (driver's side) wheel position — always verify fitment for your specific vehicle
• Reduced Brake Fade: Improved venting and surface area management keeps rotor temperatures lower for consistent pedal feel

The R1 Concepts DFC GeoPerf rotor is an ideal upgrade for performance-minded drivers looking for better braking response, improved heat management, and long-lasting rotor life compared to standard OEM replacements. Pair with R1 Concepts performance brake pads for best results.
