R1 Concepts 631-92039L RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92039L RNC Drilled & Slotted Brake Rotor is an aftermarket performance brake rotor engineered to deliver improved stopping power and thermal management over stock replacement rotors. The combined drilled and slotted surface pattern works together to evacuate heat, gas, and brake dust from the rotor face, helping reduce brake fade during demanding driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes improve heat dissipation and reduce rotor weight, while slots continuously clean and deglaze the brake pad surface for consistent bite
• Zinc Dichromate Coating: Protective coating on non-contact surfaces resists rust and corrosion, maintaining a clean appearance behind the wheel
• Precision Machined: Computer-balanced and precision-turned to strict tolerances to minimize vibration, pulsation, and noise during braking
• Direct OE Replacement: Designed as a direct bolt-on replacement with no modifications required for a straightforward installation
• High-Carbon Iron Alloy: Cast from a premium iron alloy formulation for improved strength, durability, and thermal stability compared to standard iron rotors
• Single Rotor (Left Side): Sold individually; this listing is for the left-side rotor only

The R1 Concepts RNC series drilled and slotted rotor is an ideal upgrade for drivers seeking enhanced braking performance and a sportier appearance without sacrificing everyday drivability. Compatible with a wide range of OEM-style brake pads and designed for a straightforward DIY or shop installation.
