R1 Concepts 631-92077L RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92077L RNC Series Brake Rotor is a performance drilled and slotted rotor engineered to deliver superior stopping power and consistent brake performance. The combination of cross-drilled holes and machined slots work together to evacuate heat, gas, and debris from the rotor surface, keeping your brakes operating at peak efficiency under demanding conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and improve heat dissipation, while the slots continuously clean and deglaze brake pad surfaces for consistent bite
• High-Carbon Iron Construction: Premium metallurgy ensures superior thermal capacity and resistance to warping and cracking under repeated heavy braking
• Zinc Dichromate Coating: Protective coating on non-contact surfaces resists corrosion and helps maintain the rotor's appearance over time
• Precision Balanced: Computer-balanced to OEM tolerances for smooth, vibration-free operation and reduced brake noise
• Direct OEM Replacement: Engineered as a direct bolt-on replacement with no modifications required for a straightforward installation
• OE-Style Venting: Internal vanes promote airflow through the rotor for continuous cooling during extended use

The R1 Concepts RNC Series rotor is an excellent upgrade for drivers seeking improved braking performance over stock rotors without the cost of a full racing setup. Designed to work with a wide range of performance and OEM-style brake pads, this rotor is a reliable choice for street performance and spirited driving applications.
