R1 Concepts 631-92095R RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92095R RNC Series Brake Rotor is a performance-grade drilled and slotted disc brake rotor engineered to deliver superior stopping power, heat dissipation, and rotor longevity over standard OEM replacements.

Key Features:

• Cross-Drilled Holes: Reduce rotor surface heat buildup and help expel water, gas, and debris from the braking surface for consistent, fade-resistant performance
• Diamond Slotted Pattern: Slots sweep away brake dust and pad glazing to maintain a clean, fresh contact surface between pad and rotor
• Zinc Plated Coating: Corrosion-resistant finish protects the non-braking surfaces — including the hat, hub, and vanes — from rust and premature deterioration
• G3000 Grade Cast Iron Construction: High-carbon iron formulation provides excellent thermal capacity, noise reduction, and long service life
• Direct OEM Replacement Fitment: Designed as a direct bolt-on replacement with no modifications required
• Balanced and Tested: Each rotor is precision machined and tested to meet strict dimensional tolerances for smooth, vibration-free braking

The R1 Concepts RNC Series rotor is an ideal upgrade for drivers seeking improved braking performance and durability. A proper break-in (bed-in) procedure is recommended after installation to transfer an even layer of brake pad material onto the rotor surface for optimal performance.
