R1 Concepts 631-92073L RNC Series Drilled & Slotted Brake Rotor - Left

The R1 Concepts 631-92073L is a performance-grade drilled and slotted brake rotor from R1 Concepts' RNC (Rotor Non-Coated) Series, designed as a direct-fit replacement for the left/driver-side front or rear position. Combining a cross-drilled and slotted pattern in a single rotor, this unit delivers enhanced stopping power and thermal management over stock rotors.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and improve heat dissipation, while the machined slots continuously sweep away gas, dust, and debris from the pad surface for consistent brake bite
• OE-Quality Metallurgy: Manufactured from high-carbon grey iron for superior thermal conductivity, reduced noise, and longer rotor life
• Direct Bolt-On Fitment: Engineered to match OEM specifications for a no-modification installation
• Left-Side Application: The "L" suffix designates this rotor for the left (driver) side — sold individually
• Balanced Performance: Suitable for street performance and spirited driving; compatible with most OEM and performance brake pad compounds
• Corrosion-Resistant Finish: Non-coated vane and hat area treated to resist rust and oxidation during storage and initial use

The R1 Concepts RNC drilled and slotted rotor is an ideal upgrade for drivers seeking improved brake response and fade resistance over standard OEM rotors without sacrificing daily drivability. Sold as a single rotor (left side).
