R1 Concepts 623-40095R RNC Series Drilled Brake Rotor

The R1 Concepts 623-40095R RNC Series Drilled Brake Rotor delivers enhanced stopping performance and improved heat dissipation for demanding street and performance driving conditions. Engineered to OEM fitment standards, this rotor slots directly into your existing brake system with no modifications required.

R1 Concepts' RNC (Rotor with Non-Directional Cross-Drilled) rotors are precision-machined from high-carbon grey iron for superior strength and long service life. The cross-drilled hole pattern reduces rotor surface temperature by allowing hot gases and debris to escape, helping maintain consistent brake pad contact and fade resistance during repeated braking cycles.

Key Features:

• Cross-drilled hole pattern for improved heat dissipation and reduced brake fade
• High-carbon grey iron construction for enhanced durability and noise reduction
• Precision CNC-machined for tight tolerances and OEM-quality fit
• Zinc dichromate coating on non-braking surfaces to resist corrosion and rust
• Designed for direct OEM replacement — no modifications required
• G3000 grade material meets or exceeds OEM specifications

The R1 Concepts 623-40095R is an ideal upgrade or replacement rotor for drivers seeking improved braking feel and thermal performance over a standard solid or plain-faced rotor, while maintaining everyday street drivability.
