R1 Concepts 623-54262R RNC Series Drilled Disc Brake Rotor - Right

The R1 Concepts 623-54262R is a precision-drilled disc brake rotor from R1 Concepts' RNC Series, designed as a direct-fit replacement for the right (passenger) side. Built to OEM specifications, this rotor delivers a straightforward upgrade over factory brakes with no modifications required for installation.

Constructed from G3000-grade cast iron, the rotor features precision cross-drilled holes that are countersunk to prevent stress cracking and to reduce heat buildup on the braking surface. The drilled pattern enhances ventilation, helping to dissipate heat more efficiently and reduce brake fade during repeated or heavy stops.

Key Features:

• G3000 Grade Cast Iron Construction — Meets OEM strength and dimensional standards for reliable, long-lasting performance
• Precision Cross-Drilled Holes — Countersunk design prevents cracking, improves heat dissipation, and reduces rotor temperature during braking
• Silver Zinc Plating — Corrosion-resistant coating protects the hub and vane structure from rust and oxidation
• Direct-Fit Replacement — Engineered to OEM specifications; installs without modification
• Right (Passenger) Side — Single rotor; confirm driver-side part number for axle-pair replacement

R1 Concepts recommends always replacing brake pads when installing new rotors and following a proper bed-in procedure to ensure optimal pad seating and peak braking performance. The zinc coating on the braking surface will wear away during the break-in process — this is normal and expected.
