R1 Concepts 631-32008 RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-32008 RNC Series Brake Rotor is a premium drilled and slotted performance rotor engineered to deliver superior stopping power and fade resistance over stock replacement rotors. Designed for drivers who demand more from their braking system, this rotor combines precision machining with high-quality materials to improve thermal performance and longevity.

The cross-drilled holes allow heat, gas, and debris to escape from the rotor surface, while the machined slots continuously sweep the brake pad surface clean for consistent bite and reduced glazing. Together, these features significantly improve wet-weather braking performance and help extend overall brake life.

Key Features:

• Drilled and slotted rotor design for improved heat dissipation and gas venting
• Slotted surface keeps brake pads clean and reduces glazing
• Manufactured from high-carbon grey iron for strength and consistent performance
• Precision balanced and computer-optimized for minimal vibration and noise
• Zinc dichromate corrosion-resistant coating on non-contact surfaces
• Manufactured to strict OE dimensional tolerances for direct bolt-on installation
• Designed for street performance and spirited driving conditions

The R1 Concepts RNC rotor is a direct OE replacement upgrade, requiring no modifications for installation. The durable zinc-washed finish protects non-swept surfaces from rust and corrosion, keeping the rotor looking clean and performing reliably. Pair with R1 Concepts brake pads for a fully optimized braking system.
