R1 Concepts 623-21046L RNC Series Drilled Brake Rotor

The R1 Concepts 623-21046L RNC Series Drilled Brake Rotor is a direct-fit replacement rotor engineered to deliver improved braking performance over stock. Precision-drilled holes across the rotor face help evacuate heat, gas, and debris from the braking surface, maintaining consistent pad contact and reducing brake fade under demanding conditions.

Key Features:

• Precision drilled holes for enhanced heat dissipation and gas evacuation
• Direct OE-replacement fit — no modifications required
• Manufactured from high-carbon gray iron for durability and thermal stability
• Balanced and tested to minimize vibration and noise
• Zinc dichromate coating on non-friction surfaces resists corrosion and rust
• Meets or exceeds OEM specifications for safe, reliable stopping power

R1 Concepts rotors are manufactured to strict tolerances and undergo rigorous quality control to ensure proper fitment and long service life. The RNC drilled rotor is an excellent upgrade for drivers seeking better thermal management and a performance appearance without sacrificing everyday drivability.
