R1 Concepts 623-58036R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-58036R is an RNC Series cross-drilled brake rotor engineered to deliver enhanced stopping performance over a standard OEM replacement rotor. Built to OEM specifications for a direct-fit installation with no modifications required, this rotor is a straightforward upgrade for drivers seeking improved heat management and a more aggressive look.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are chamfered and countersunk to reduce heat buildup, improve ventilation, and minimize the risk of cracking during the bed-in process
• G3000 Grade Cast Iron Construction: High-quality iron alloy provides excellent strength, stability, and consistent braking performance mile after mile
• Zinc Plating Corrosion Protection: Silver zinc coating on the hat, vanes, and non-contact surfaces resists rust and extends rotor life — note that coating on the braking surface will wear away during the normal bed-in process
• OEM Direct Fit: Engineered to match OEM dimensions and bolt patterns; bolt-on installation with no drilling, cutting, or modification needed
• Right/Passenger Side: This is a single rotor for the right (passenger) side position — verify your application to ensure correct placement

R1 Concepts RNC Series rotors are an ideal choice for daily driving, street performance, and light towing applications. A proper brake bed-in procedure is recommended after installation to achieve optimal pad transfer and consistent braking performance.
