R1 Concepts 631-58014R RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-58014R is an RNC Series drilled and slotted performance brake rotor engineered to deliver superior stopping power and thermal management over stock replacement rotors. Designed as a direct-fit upgrade, this rotor combines precision cross-drilling and diamond-slot milling to maximize braking efficiency, reduce heat buildup, and extend pad life.

Key Features:

• Cross-Drilled Holes: Strategically placed drill holes allow hot gases and heat to escape from the rotor surface, reducing rotor temperatures and brake fade during demanding use
• Slotted Surface: Machined slots continuously sweep the brake pad surface clean of debris, dust, and gases, preventing pad glazing and maintaining consistent bite
• Silver Zinc Coating: A protective silver zinc finish covers the hat, vanes, and non-friction surfaces to resist corrosion and deliver a clean, performance appearance out of the box
• G3000 Metallurgy: Manufactured from high-grade G3000 gray iron casting for excellent strength, heat absorption, and durability
• Direct OE Replacement Fit: Designed to match original equipment mounting dimensions for straightforward installation with no modifications required
• Balanced and Tested: Each rotor is precision balanced and tested to minimize vibration and pedal pulsation

The R1 Concepts RNC Series rotor is an ideal upgrade for drivers seeking improved braking performance for street, towing, or spirited driving applications. Sold individually — confirm fitment before ordering.
