R1 Concepts 613-11021R RNC Series Slotted Brake Rotor

The R1 Concepts 613-11021R RNC Series Slotted Brake Rotor delivers enhanced stopping performance over stock replacement rotors. Engineered with precision-machined slots across the rotor face, this rotor continuously sweeps brake dust, gases, and debris away from the pad surface — maintaining consistent contact and reducing brake fade under repeated or aggressive braking conditions.

R1 Concepts rotors are manufactured from high-carbon grey iron for superior heat dissipation and long-lasting durability. Each rotor undergoes precise computer-controlled balancing and is finished with a zinc dichromate coating on non-swept surfaces to resist corrosion and rust.

Key Features:

• Slotted rotor design for improved pad bite and heat venting
• High-carbon grey iron construction for excellent thermal management
• Zinc dichromate coating on non-friction surfaces for corrosion resistance
• Computer-balanced for vibration-free performance
• Direct OE replacement fit — no modifications required
• Manufactured to strict dimensional tolerances for consistent pedal feel

The R1 Concepts RNC Series is an excellent upgrade for drivers seeking improved braking performance and rotor longevity over standard OEM rotors, while remaining compatible with most OEM and aftermarket brake pads.
