R1 Concepts 631-92076L RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92076L RNC Series Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver superior stopping power, improved heat dissipation, and consistent fade resistance under demanding driving conditions. Designed as a direct OEM-style replacement, this rotor installs without modification for a straightforward, hassle-free upgrade.

R1 Concepts manufactures this rotor using G3000-grade premium cast iron, the same specification used in original equipment rotors, ensuring long-lasting durability and smooth, quiet operation. The rotor undergoes a precision computer-balanced machining process to minimize vibration and eliminate brake pedal pulsation.

Key Features:

• Drilled and Slotted Surface: Cross-drilled holes vent heat and gases away from the rotor face, while machine-cut slots sweep debris and brake dust from the pad surface for consistent, reliable contact
• G3000 Cast Iron Construction: High-grade iron formulation resists cracking and warping under repeated heat cycles
• Zinc Dichromate Coating: Corrosion-resistant finish on non-contact surfaces protects against rust and extends rotor life
• Computer Balanced: Precision machining ensures runout is within OEM tolerances, eliminating vibration and steering wheel shimmy
• Direct OEM Replacement: Engineered to match original equipment specifications for bolt-on installation
• Performance Upgrade: Ideal for spirited street driving, light track use, and towing applications where stock rotors fall short

The R1 Concepts RNC Series represents an excellent balance of performance and value, delivering measurable improvements in braking response and thermal management compared to standard smooth rotors. Each rotor is individually inspected to meet strict quality standards before leaving the factory.
