R1 Concepts 623-16004R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-16004R RNC Series Cross-Drilled Brake Rotor is a direct-fit performance replacement disc rotor engineered to deliver improved stopping power and heat dissipation over a standard OEM rotor. Precision-machined to OEM specifications, this drilled rotor installs without modification for a straightforward brake service.

Key Features:

• Cross-Drilled Design: Strategically placed drill holes channel heat away from the rotor face, reducing operating temperatures and minimizing brake fade during repeated or heavy stops
• Chamfered Drill Holes: Each hole is chamfered to reduce stress concentration, helping the rotor resist cracking under thermal cycling
• Corrosion-Resistant Coating: Zinc-plated non-friction surfaces protect against rust and corrosion, maintaining rotor integrity and appearance over time
• Precision Machined: Manufactured to tight tolerances for proper fit, minimal runout, and vibration-free braking performance
• Direct OEM Replacement: Bolt-on fitment with no modifications required; compatible with OEM and aftermarket brake pads
• Sold Individually: Single rotor — verify position (front/rear, left/right) before ordering

R1 Concepts rotors are manufactured from high-grade gray iron and balanced to reduce pedal pulsation and rotor vibration. The RNC series drilled rotor is well-suited for daily driving applications where improved wet-weather braking response and thermal management over a standard blank rotor are desired.
