R1 Concepts 830-31001L DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-31001L DFC GeoPerf Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand superior stopping power and consistent brake feel. Part of R1 Concepts' GeoPerf series, this rotor combines precision drilled holes and machined slots to deliver enhanced heat dissipation, reduced brake fade, and improved wet-weather braking performance.

Key Features:

• Drilled & Slotted Design: Strategically placed drill holes and slots channel heat, gas, and debris away from the rotor surface, keeping brake temperatures in check during demanding driving conditions
• GeoPerf Geometry: Geometrically optimized slot and hole pattern maximizes rotor strength while improving pad bite and overall braking efficiency
• G3000 Grade Cast Iron: Manufactured from premium G3000 grade cast iron for long service life and consistent rotor hardness
• Zinc Dichromate Coating: Protective anti-rust coating on the hat and non-swept areas helps prevent corrosion during storage and service
• Precision Balanced: Each rotor is precision machined and balanced to OEM-level tolerances to minimize vibration and pedal pulsation
• Direct OEM Replacement: Bolt-on fitment with no modifications required — designed as a direct replacement for the original equipment rotor
• Left Side (Driver Side): MPN 830-31001L is the left/driver-side rotor

The R1 Concepts DFC GeoPerf rotor is an excellent upgrade for performance-oriented street driving, spirited canyon runs, or track day use where thermal management and consistent brake response are critical. Pair with R1 Concepts brake pads for optimized system performance.
