R1 Concepts 613-40100L RNC Series Slotted Brake Rotor

The R1 Concepts 613-40100L RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand consistent, reliable stopping power. Featuring a precision-cut slotted surface pattern, this rotor continuously sweeps debris, gas, and heat away from the brake pad contact surface — helping to maintain optimal friction and reduce brake fade under demanding conditions.

Key Features:

• Slotted Design: Slots channel away heat, gases, and particulate matter to keep the braking surface clean and effective
• Precision Machined: Manufactured to strict tolerances for smooth, vibration-free braking and minimal pedal pulsation
• Direct-Fit Replacement: Engineered as a bolt-on replacement with no modifications required
• Corrosion-Resistant Coating: Protective finish helps guard against rust and corrosion on non-friction surfaces
• Balanced Construction: Designed for even wear and long service life

The R1 Concepts RNC Series rotor is an excellent upgrade over standard OE rotors, offering improved thermal management and consistent brake feel. Part number 613-40100L denotes the left-side (driver-side) application. Suitable for street driving and spirited performance use.
