R1 Concepts 631-92071R RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92071R is a high-performance RNC Series drilled and slotted brake rotor engineered to deliver superior stopping power over stock OEM rotors. Combining a cross-drilled and slotted surface pattern, this rotor is designed to evacuate heat, gas, and brake dust from the rotor-pad interface — keeping your brakes cooler and more responsive under demanding driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce unsprung weight and dissipate heat, while the slots continuously clean and deglaze brake pad surfaces for consistent bite
• G3000 Grade Metallurgy: Manufactured from high-carbon G3000 cast iron for excellent thermal capacity, noise reduction, and long service life
• OEM-Quality Fit: Engineered to match original equipment specifications for a direct bolt-on installation with no modifications required
• Zinc Dichromate Coating: Protective corrosion-resistant coating on non-friction surfaces prevents rust and improves overall rotor appearance
• Precision Machined: Computer-balanced and precision machined to tight tolerances to minimize brake vibration and pedal pulsation
• Vented Construction: Internal vane venting promotes airflow through the rotor for continuous cooling during repeated brake applications

The R1 Concepts RNC Series rotor is an ideal upgrade for drivers seeking improved braking performance for street, highway, or light track use. It pairs perfectly with R1 Concepts' eLine or ZZZ Series brake pads for a complete, matched brake system upgrade.
