R1 Concepts 623-54134R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-54134R RNC Series Drilled Brake Rotor is a precision-engineered performance disc rotor designed to deliver consistent, fade-resistant stopping power. R1 Concepts manufactures each rotor to exacting tolerances, providing a direct-fit replacement that requires no modifications for installation.

The drilled design promotes aggressive heat dissipation, reducing rotor surface temperatures during repeated or hard braking events. Precision-countersunk drill holes are engineered to minimize stress concentrations, helping to guard against cracking over the rotor's service life. The result is a rotor that runs cooler, lasts longer, and maintains consistent pedal feel across a wide range of driving conditions.

Key Features:

• Cross-Drilled Design: Precision-drilled holes vent heat and gas buildup from the rotor surface, reducing brake fade
• Direct-Fit Replacement: Engineered to OEM mounting specifications for a straightforward installation with no modifications required
• High-Quality Construction: Machined from premium gray iron for strength, thermal stability, and long service life
• Corrosion-Resistant Finish: Protective coating on non-friction surfaces helps resist rust and corrosion during storage and service
• Balanced Performance: Suitable for street driving, daily commuting, and moderate performance use

The R1 Concepts 623-54134R is sold as a single rotor. Always replace brake pads when installing new rotors, and follow the manufacturer's recommended bed-in procedure to ensure optimal performance and even pad transfer.
