R1 Concepts 631-92064L RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92064L is a drilled and slotted brake rotor from R1 Concepts' RNC Series, engineered to deliver improved braking performance over standard OEM rotors. This is a left/driver-side replacement rotor designed for direct-fit installation.

R1 Concepts' drilled and slotted design provides multiple performance benefits over solid or plain-faced rotors. The cross-drilled holes allow heat, gases, and moisture to escape from the pad-to-rotor contact surface, while the machined slots continuously clean and refresh the brake pad face for consistent, fade-resistant stopping power.

Key Features:

• Cross-Drilled & Slotted Pattern – Improves heat dissipation, reduces brake fade, and expels water and debris from the braking surface
• RNC Series Nano Coating – Corrosion-resistant coating protects the rotor hat, vanes, and non-swept surfaces from rust and premature deterioration
• Direct-Fit Replacement – Engineered to match OEM specifications for straightforward, bolt-on installation
• Premium Grade Iron – High-quality cast iron construction provides durability and consistent thermal performance
• Left/Driver-Side Rotor – Sold individually; verify correct side before ordering
• Balanced & Tested – Each rotor is precision balanced to minimize vibration and pedal pulsation

The R1 Concepts 631-92064L RNC drilled and slotted brake rotor is an ideal upgrade for drivers seeking improved stopping performance and rotor longevity compared to standard OEM replacements.
