R1 Concepts 613-84005L RNC Series Slotted Disc Brake Rotor

The R1 Concepts 613-84005L RNC Series Slotted Brake Rotor is a performance-grade disc brake rotor engineered to deliver improved stopping power and consistent braking performance over the life of the rotor. Designed as a direct OE replacement, this rotor installs without modification for a quick, straightforward swap.

Key Features:

• Diamond Slot Technology: Exclusive slotted pattern increases brake pad bite, allows heat and gas to escape the pad-to-rotor interface, and serves as a visual rotor wear indicator
• G3000 Grade Cast Iron: Manufactured from high-grade G3000 iron for optimal strength, thermal stability, and long service life
• Double Disc Ground Surface: Precision double disc grinding promotes faster, more even brake pad bed-in and contributes to quieter, smoother stops
• Zinc Plated Coating: Full-rotor zinc plating protects the hub, hat, and vane structure from corrosion, extending rotor lifespan and maintaining appearance — the coating on the braking surface will wear off during normal break-in
• OE Specifications: Manufactured to original equipment dimensions and tolerances for a direct-fit installation with no modifications required
• Slotted Pattern: Slotted-only design (no cross-drilling) for improved pad bite and heat dissipation while maintaining maximum rotor integrity

A proper break-in (bed-in) procedure is recommended after installation to fully seat the brake pads to the new rotor surface and achieve optimal braking performance. Always replace brake pads when installing new rotors.
