R1 Concepts 631-58018L Performance Drilled and Slotted Brake Rotor - Left

The R1 Concepts 631-58018L RNC Series Performance Brake Rotor delivers enhanced stopping power through its precision-engineered drilled and slotted design. This left-side rotor combines cross-drilled holes with diamond slot technology to maximize braking performance, heat dissipation, and rotor longevity.

Key Features:

• Cross-drilled design reduces heat buildup by up to 105°F, preventing brake fade during demanding driving conditions
• Diamond slot technology removes brake dust, road debris, and gases while preventing pad glazing
• Manufactured from high-grade G3000 cast iron for superior strength, stability, and durability
• Zinc plating provides corrosion resistance and extends rotor service life
• Precision-machined to OEM specifications for direct bolt-on installation with no modifications required
• Mill-balanced design ensures smooth, vibration-free stopping and quieter operation
• Non-directional finish promotes faster brake pad bed-in and consistent performance
• Diamond-tipped slot ends serve as wear indicators for easy replacement timing

Ideal for daily driving, street performance, light towing, and spirited driving applications. The drilled and slotted pattern enhances brake pad bite, extends pad life, and maintains optimal contact between pad and rotor surface in both wet and dry conditions. Each rotor is manufactured to exacting tolerances and undergoes rigorous quality control inspection to ensure reliable, trouble-free performance.
