Product Details

The R1 Concepts 623-48013L is a precision-drilled disc brake rotor from R1 Concepts' RNC series, engineered to deliver reliable stopping power and improved thermal performance over standard OEM rotors. Manufactured to original equipment specifications, this rotor installs without modification for a direct-fit replacement.

Key Features:

  • Precision Cross-Drilled Holes: Countersunk drill pattern maximizes heat dissipation and ventilation, reducing rotor operating temperature and minimizing brake fade
  • Chamfered Drill Holes: Reduces stress concentration at each hole to help prevent cracking under repeated thermal cycling
  • G3000 Grade Iron Construction: Cast from high-grade G3000 iron for the durability, thermal stability, and consistent friction surface required by OEM and performance applications
  • Zinc Plating Corrosion Protection: Full-coverage zinc coating on the hat, hub, and vane structure guards against rust and corrosion, extending service life and maintaining appearance
  • OE Spec Direct Fit: Manufactured to original equipment dimensions — no machining, adapters, or modifications required for installation
  • Left / Driver Side: This rotor is specifically designed for the left (driver) side axle position

R1 Concepts recommends following a proper bed-in procedure after installation to ensure even pad transfer and optimal braking performance. Always replace brake pads when installing new rotors and use pads compatible with drilled rotor surfaces.

I've had nothing but oof experiences doing business with THMotorsports. Best price for spark plugs out of anyone else. Fastest shipping with reasonable rates.

Service was great. I received the cleats faster than expected.

Product shipped from Norfolk VA, which was very convenient to me in NC. Arrived in a few days from ordering.

Looks like a great exhaust thanks guys!

Thanks!

Website said the system I ordered was different from what the order confirmation said. I called customer service who said they could not confirm what was shipped and told me to send inquiry via email. In the end the system fit, but If you are not going to help customers over the phone, don't have a customer service number!

I would like to rate 5 stars. However item description doesn't contain 3 year old manufacture date.
