R1 Concepts 830-31103R GEO-Carbon Drilled Slotted Brake Rotor

The R1 Concepts 830-31103R is a GEO-Carbon Series cross-drilled and diamond-slotted brake rotor engineered for drivers who demand consistent, high-performance stopping power. Built by DFC (Disc Friction Components) and sold under the R1 Concepts brand, this rotor features a Geomet anti-corrosion coating over the hub and vane structure, providing superior rust protection, a longer service life, and a cleaner appearance compared to standard zinc-coated rotors.

Key Features:

• Cross-Drilled Holes: Promote heat dissipation and help expel gas and debris from the pad-rotor interface for consistent bite
• Diamond Slotted Pattern: Continuously sweeps the brake pad surface to maintain a fresh contact edge and reduce fade under repeated hard stops
• Geomet Coating: High-performance anti-corrosion finish applied to the hat and vane areas for long-lasting protection and improved appearance
• Right-Side Rotor: Directionally designed for correct fitment on the right (passenger) side of the vehicle
• OE-Quality Machining: Precision balanced and machined to tight tolerances for smooth, vibration-free braking
• Direct OE Replacement: Bolt-on installation with no modifications required

Please note that upon initial installation, the Geomet coating on the braking surface will wear away during the bed-in process — this is normal. The coating on the hub and inner vane structure remains intact. A proper break-in procedure is recommended to seat the pads and maximize rotor performance.
