R1 Concepts 631-92032R RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92032R RNC Series Drilled and Slotted Brake Rotor delivers enhanced stopping performance and improved thermal management over standard OEM rotors. Engineered for drivers who demand more from their braking system, this rotor combines precision-drilled holes and machined slots to maximize heat dissipation, reduce brake fade, and extend pad life under both everyday and spirited driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor mass and allow gases and heat to escape quickly, while slots continuously clean and deglaze brake pad surfaces for consistent bite
• High-Carbon Gray Iron Construction: Provides superior strength, reduced vibration, and a quieter, more consistent braking feel compared to standard iron rotors
• Zinc Dichromate Coating: Non-braking surfaces are coated to resist corrosion and maintain a clean, attractive appearance over the life of the rotor
• Precision Balanced: Computer-balanced to minimize vibration and pulsation, ensuring smooth pedal feel and reduced steering wheel shimmy
• Direct OEM Replacement: Designed as a direct bolt-on replacement requiring no modification for a straightforward installation
• G3000 Grade Metal: Meets or exceeds OEM specifications for metallurgical quality and performance standards

The R1 Concepts RNC Series rotor is an ideal upgrade for drivers seeking improved braking responsiveness, reduced brake fade during repeated hard stops, and a longer service life. Sold individually — confirm quantity needed for your application.
