R1 Concepts 623-40112R RNC Series Drilled Disc Brake Rotor - Right

The R1 Concepts 623-40112R RNC Series Drilled Brake Rotor is a direct OE-replacement rotor engineered for reliable, consistent stopping performance. Part of R1 Concepts' RNC (Replacement No Coat) line, this rotor features a cross-drilled pattern that improves heat dissipation, reduces brake fade, and helps expel gases and debris from the rotor surface during braking.

Manufactured from high-carbon grey iron, this rotor is precision-machined to strict tolerances for a proper OEM-style fitment with no modifications required. The drilled design also reduces unsprung rotational weight compared to a standard blank rotor, contributing to improved brake response and pedal feel.

Key Features:

• RNC Series – Replacement-grade rotor designed as a direct OEM substitute
• Cross-drilled holes – Enhance thermal cooling and reduce brake fade under repeated stops
• High-carbon grey iron construction – Provides strength, durability, and consistent bite
• Precision machined – Meets or exceeds OEM dimensional specifications for proper fitment
• Right-side application – Designed specifically for the right (passenger) side position
• No coating required – Ready to install out of the box

The R1 Concepts 623-40112R is an excellent choice for drivers seeking an upgraded replacement rotor that improves upon the stock unit with added drilled cooling technology, while maintaining the ease of a bolt-on installation.
