R1 Concepts 613-39007L RNC Series Slotted Brake Rotor

The R1 Concepts 613-39007L RNC Series Slotted Brake Rotor is a performance-engineered replacement rotor designed to deliver consistent, reliable stopping power. R1 Concepts manufactures this rotor using high-grade grey iron casting, ensuring excellent heat dissipation and long service life under both everyday driving and spirited use.

The slotted surface design continuously sweeps away heat, gases, and debris from the brake pad contact surface, maintaining a clean bite and reducing brake fade during repeated or heavy braking. Each rotor is precision-machined to strict tolerances for a smooth, vibration-free installation.

Key Features:

• Slotted rotor design for improved heat and gas evacuation
• High-grade grey iron construction for durability and thermal stability
• Precision-machined for minimal runout and consistent pad contact
• Direct OE-replacement fit — no modifications required
• Corrosion-resistant coating on non-friction surfaces
• Left-side (driver side) application

The R1 Concepts RNC Series rotor is an ideal upgrade or direct replacement for worn OEM rotors, offering a noticeable improvement in braking feel and fade resistance. Compatible with standard OEM-style brake pads, making it a straightforward drop-in upgrade.
