R1 Concepts 631-19002L RNC Series Drilled & Slotted Brake Rotor - Left

The R1 Concepts 631-19002L RNC Series Brake Rotor is a premium drilled and slotted performance rotor engineered to deliver superior stopping power and heat dissipation over stock replacement rotors. Designed as a direct-fit replacement, this rotor installs without modification for a straightforward upgrade from OEM braking components.

R1 Concepts' RNC (Rounded & Natural Coated) Series rotors feature precision drilled holes and machined slots across the rotor face. The drilled holes reduce overall rotor weight and allow heat, gas, and debris to escape from the rotor surface, while the slots continuously clean and refresh the brake pad contact surface for consistent, fade-resistant braking performance.

Key Features:

• Drilled & Slotted Design: Improves heat dissipation, reduces brake fade, and sweeps away dust and debris from the pad surface
• Rounded Drill Holes: Chamfered/rounded edges around drill holes reduce stress concentration and minimize the risk of rotor cracking
• Natural Coated Finish: Corrosion-resistant coating on the hat and non-swept areas protects against rust and extends rotor life
• Direct OE Replacement Fit: Engineered to match OEM specifications for easy bolt-on installation
• Left Side (Driver Side): This rotor is designed for the left/driver-side position
• High-Carbon Metallurgy: Premium gray iron casting for consistent performance and durability

The R1 Concepts 631-19002L is an excellent choice for drivers seeking a performance upgrade over standard rotors while maintaining street-friendly drivability. Compatible with a wide range of brake pad compounds, these rotors are well-suited for daily driving with spirited use.
