Product Details

The R1 Concepts 613-42008L RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver improved stopping power and heat dissipation over standard OEM rotors. Designed for drivers who demand more from their braking system, this rotor features precision-machined slots that continuously sweep debris, gas, and brake dust away from the rotor surface for consistent, fade-resistant braking performance.

Key Features:

  • Slotted Design: Precision-cut slots help expel heat, gas, and debris from the rotor surface, maintaining consistent pad contact and reducing brake fade
  • RNC Series: R1 Concepts' RNC line is engineered for street and performance driving applications, balancing durability with enhanced braking response
  • Direct OEM Replacement: Designed as a direct fit replacement with no modifications required for a straightforward installation
  • Zinc Washed Finish: Protective zinc coating helps resist corrosion and rust during storage and initial break-in period
  • Balanced and Tested: Each rotor is computer-balanced and tested for runout to ensure smooth, vibration-free braking
  • High-Quality Casting: Made from premium gray iron for long-lasting durability and consistent thermal performance

The R1 Concepts 613-42008L is the left-side (driver side) rotor in the RNC series lineup. Whether upgrading from a worn OEM rotor or stepping up to a slotted performance rotor for the first time, this unit provides a reliable, performance-oriented solution. For best results, pair with compatible R1 Concepts brake pads and perform a proper bed-in procedure after installation.

Two day shipping took a week but happy with the product, came as advertised.

Very good service

Surprised how through the shopping experience was and my tire was delivered extremely fast will definitely be back for future purchases:)

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

It would have been better if you listed the dimensions so hopefully it fits

First transaction with THMotorsports. It was seamless, smooth and quick.
