R1 Concepts 613-76131L RNC Series Slotted Disc Brake Rotor

The R1 Concepts 613-76131L is a slotted disc brake rotor from R1 Concepts' RNC series, engineered to deliver consistent, reliable stopping power for street and performance driving applications. Sold as a single left/driver-side rotor, it is precision-manufactured to meet or exceed OEM fit and function standards.

Key Features:

• Slotted rotor design removes brake dust, gases, and debris from the pad-to-rotor contact surface, reducing brake fade and extending pad life
• Diamond-tipped slot ends serve as a built-in wear indicator — when the tips wear flush, it signals time for rotor replacement
• Zinc-plated coating on non-braking surfaces protects against corrosion for improved appearance and longevity
• Precision-machined construction ensures proper fitment and smooth, vibration-free braking performance
• Left/driver-side application (single rotor) — verify fitment for your specific vehicle before ordering
• Designed for passenger vehicles and light-duty trucks

R1 Concepts rotors undergo a zinc-plating process that fully covers the rotor at the time of delivery. During the initial break-in period, the coating on the braking surface will naturally wear away where the pads contact the rotor — this is expected and normal. A proper bed-in procedure is recommended after installation to ensure optimal performance and even pad transfer.
