R1 Concepts 631-31183D RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-31183D RNC Series Drilled & Slotted Brake Rotor delivers enhanced stopping performance over stock replacement rotors. Combining precision cross-drilling and linear slots, this rotor continuously sweeps brake pad gases, heat, and debris away from the friction surface to maintain a consistent, high-performance bite throughout the brake cycle.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce unsprung weight and aid in heat dissipation, while the slots channel away gas and debris for improved pad bite
• Premium G3000 Metallurgy: Cast from high-carbon G3000 iron for superior thermal stability and reduced brake fade under demanding conditions
• Zinc Dichromate Coating: Corrosion-resistant finish on the non-friction surfaces prevents rust and maintains a clean appearance
• Precision Machined: Computer-balanced and precision machined to OEM tolerances for smooth, vibration-free braking and easy installation
• OEM-Style Direct Fit: Bolt-on replacement requiring no modifications; designed as a direct upgrade over factory rotors
• Silver Zinc Plated Hat: Adds additional corrosion protection to the rotor hat for long-term durability

The R1 Concepts RNC series is an ideal upgrade for drivers seeking improved braking performance in street and light performance driving applications. This rotor is designed for a direct bolt-on fit to the applicable vehicle, offering a noticeable improvement in heat management and pad performance over standard smooth rotors.
