R1 Concepts 631-20008L RNC Drilled & Slotted Brake Rotor - Left

The R1 Concepts 631-20008L RNC Drilled and Slotted Brake Rotor is a performance-grade replacement rotor engineered to deliver improved stopping power and thermal management over standard OE rotors. Designed as a direct-fit, left-side replacement, this rotor is built to R1 Concepts' proven RNC series specifications for drivers seeking an upgrade without sacrificing daily drivability.

Key Features:

• Drilled and Slotted Design: Cross-drilled holes and machined slots work together to dissipate heat, expel gas and debris from the pad surface, and reduce brake fade during demanding use
• OE-Style Direct Fit: Engineered as a direct replacement with OEM-matching hub dimensions, bolt pattern, and hat depth for straightforward installation
• Zinc Dichromate Coating: Non-friction surfaces are coated to resist rust and corrosion, keeping the rotor looking clean behind the wheel
• Balanced Vane Design: Internal vanes promote airflow through the rotor for consistent cooling during extended or spirited driving
• Left-Side Specific: Directional slot pattern is engineered for the left (driver) side to maximize pad sweep and braking efficiency
• G3000 Grade Iron Casting: Made from high-grade iron for consistent friction characteristics and long service life

The R1 Concepts RNC series offers an ideal balance of performance and value, making it a popular choice for drivers looking to upgrade from worn OE rotors. Compatible with standard ceramic or semi-metallic brake pads, this rotor is ready for installation straight out of the box after standard bedding procedure.
