R1 Concepts 830-54130L GeoPerf Drilled Slotted Brake Rotor Left/Driver Side

The R1 Concepts 830-54130L GeoPerf Drilled and Slotted Brake Rotor is a high-performance, left/driver-side replacement rotor engineered for drivers who demand superior stopping power and long-lasting durability. Built under R1 Concepts' DFC (Dynamic Friction Company) GeoPerf line, this rotor combines cross-drilled holes and diamond-cut slots in a single unit designed for both daily street use and more demanding driving conditions.

Key Features:

• Cross-Drilled & Diamond Slotted Design: Promotes maximum heat dissipation, reduces brake fade, and helps expel gas and debris from the rotor surface for consistent, confident braking
• Geomet Protective Coating: Premium corrosion-resistant Geomet finish protects the hub, hat, and vane structure from rust and oxidation, extending rotor life and maintaining a clean appearance
• Left/Driver Side Fitment: Directionally matched for the driver-side position; sold as a single rotor
• OEM-Quality Construction: Precision-machined to exact dimensional tolerances for a direct OEM replacement fit with no modifications required
• High-Performance Street Use: Suitable for everyday driving, spirited street performance, and moderate track use

Break-In Note: When first received, the rotor will be fully covered with the Geomet protective coating. During the initial bed-in process, the coating on the braking surface (the pad contact area) will naturally wear away, leaving the hub, hat, and inner vane structure coated for ongoing corrosion protection.

The R1 Concepts GeoPerf series delivers a balanced upgrade over standard OEM rotors, combining improved thermal performance with a corrosion-resistant finish for a rotor that looks and performs great mile after mile.
