R1 Concepts 613-42004R RNC Series Slotted Brake Rotor

The R1 Concepts 613-42004R RNC Series Slotted Brake Rotor is a high-performance direct-fit replacement rotor engineered for drivers who demand improved stopping power and consistent brake performance. The RNC line features precision-machined slots that continuously sweep debris, gas, and heat away from the rotor surface, maintaining a clean contact patch between pad and rotor for fade-resistant, reliable braking.

Key Features:

• Slotted rotor design for improved heat dissipation and reduced brake fade under demanding conditions
• Precision CNC-machined slots that clear debris, gas, and water from the braking surface
• High-carbon grey iron construction for excellent thermal capacity and long service life
• Zinc-washed non-braking surfaces to resist corrosion and maintain a clean appearance
• Direct OE replacement fitment — no modifications required for installation
• Balanced and tested for smooth, vibration-free operation

The R1 Concepts RNC slotted rotor is an ideal upgrade from a standard OE rotor, delivering enhanced performance for street driving, towing, or spirited use. Each rotor is manufactured to meet or exceed OEM specifications for a confident, straightforward installation.
