R1 Concepts 613-32003R RNC Series Slotted Brake Rotor

The R1 Concepts 613-32003R RNC Series Slotted Brake Rotor is a performance-oriented replacement rotor engineered to deliver consistent stopping power and improved thermal management over stock rotors. Designed as a direct OE-style fitment, this rotor slots into your existing brake system without modification.

The slotted surface design continuously sweeps the brake pad face clean of gas, dust, and debris, maintaining fresh pad contact and reducing fade under repeated or heavy braking. The slots also help vent heat away from the rotor surface, extending pad and rotor life during demanding driving conditions.

Key Features:

• Slotted rotor design for improved heat dissipation and pad degassing
• Direct OEM replacement fitment — no modifications required
• Manufactured from high-carbon gray iron for strength and noise reduction
• Precision machined for minimal runout and smooth, vibration-free braking
• Corrosion-resistant coating on non-friction surfaces to resist rust and extend service life
• Balanced for smooth, consistent brake pedal feel
