R1 Concepts 631-75009R Drilled Slotted Brake Rotor RNC Series - Rear

The R1 Concepts 631-75009R is a high-performance rear brake rotor featuring an advanced drilled and slotted design for superior stopping power. Part of the RNC (R1 Concepts) series, this rotor combines precision engineering with enhanced cooling and debris evacuation capabilities to deliver consistent braking performance under demanding conditions.

Key Features:

• Drilled and slotted design improves heat dissipation and reduces brake fade
• Cross-drilled holes prevent gas buildup between pad and rotor surface
• Machined slots continuously refresh the brake pad surface and evacuate debris
• Manufactured from high-quality cast iron for durability and reliability
• Precision-balanced to minimize vibration and ensure smooth operation
• Mill-balanced and ready to install out of the box
• Enhanced wet weather performance with improved water dispersal

The RNC series rotors from R1 Concepts provide an excellent upgrade for drivers seeking improved braking performance over stock rotors. The combination of drilling and slotting maximizes surface contact while maintaining optimal operating temperatures, making this rotor ideal for both street and spirited driving applications.
