R1 Concepts 830-31157L Drilled Slotted Performance Brake Rotor - Front Left

The R1 Concepts 830-31157L is a high-performance drilled and slotted brake rotor engineered to deliver superior stopping power and heat dissipation. Part of the GeoPerf DFC (Dual Friction Coating) series, this front left rotor features a precision-machined design with cross-drilled holes and curved slots that work together to evacuate heat, gases, and debris from the braking surface.

Key Features:

• Cross-drilled and slotted design maximizes cooling and reduces brake fade during aggressive driving
• DFC (Dual Friction Coating) protects against corrosion and rust while reducing break-in time
• Premium G3000 metallurgy castings ensure consistent performance and extended rotor life
• Curved slot pattern efficiently channels away water, dust, and gas buildup
• Mill-balanced to minimize vibration and ensure smooth, quiet operation
• Direct OEM replacement fitment for hassle-free installation

R1 Concepts GeoPerf rotors are designed for drivers seeking enhanced braking performance without compromising daily drivability. The drilled and slotted configuration provides improved bite and modulation while maintaining rotor integrity under demanding conditions.
