R1 Concepts 613-92058L RNC Slotted Disc Brake Rotor

The R1 Concepts 613-92058L is a slotted disc brake rotor from R1 Concepts' RNC Series, engineered as a direct OEM-replacement upgrade for drivers seeking improved braking performance over a standard blank rotor. Designed for a precise, bolt-on fit with no modifications required, this rotor delivers consistent stopping power for daily driving and light performance use.

Key Features:

• Slotted Rotor Design: Precision-machined slots remove brake dust, gas, and road debris from the rotor surface, preventing pad glazing and extending the service life of both the rotor and brake pads
• Wear-Indicator Slots: The slot pattern doubles as a visual wear indicator — when the slots are no longer visible, rotor replacement is due
• G3000-Grade Cast Iron Construction: High-quality gray iron casting delivers strength, stability, and consistent braking performance stop after stop
• OEM-Spec Bolt-On Fit: Engineered to original equipment specifications for a hassle-free, direct replacement installation
• Non-Directional Finish: Promotes faster, more even pad bed-in, helping minimize noise and vibration during the break-in period
• Single Rotor (Left Side): Sold individually; the "L" suffix denotes the left-side / driver-side rotor position

The R1 Concepts RNC Series slotted rotor is well-suited for daily commuting, light towing, and street driving where improved thermal management and pad life are priorities. It pairs seamlessly with R1 Concepts ceramic or semi-metallic brake pads for a complete brake system upgrade.
