R1 Concepts 830-54226L DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-54226L DFC GeoPerf Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand superior stopping power and thermal management. Part of R1 Concepts' GeoPerf (Geometrically Optimized Performance) line, this rotor features a precisely engineered combination of drilled holes and machined slots designed to work together for maximum braking efficiency.

Key Features:

• Drilled & Slotted Surface: Strategically placed drill holes reduce rotor weight and help dissipate heat, while the slots continuously sweep brake pad gases and debris from the contact surface for consistent bite
• GeoPerf Geometry: R1 Concepts' proprietary slot and hole pattern is optimized using geometric modeling to maximize surface contact area and rotor longevity
• Premium G3000 Cast Iron: Manufactured from high-quality G3000 grade cast iron for durability, longevity, and excellent thermal conductivity
• Zinc Dichromate Coating: Corrosion-resistant coating on non-friction surfaces protects against rust and improves appearance
• Direct OE Replacement: Engineered as a direct bolt-on replacement with no modifications required
• Balanced & Precision Machined: Each rotor is precision-machined and balanced to minimize vibration and pedal pulsation

The R1 Concepts DFC GeoPerf rotor is an excellent upgrade over standard OE rotors, delivering improved fade resistance and consistent performance under demanding driving conditions including spirited street driving and light track use.
