R1 Concepts 613-31161R RNC Series Slotted Brake Rotor

The R1 Concepts 613-31161R RNC Series Slotted Brake Rotor is a direct-fit performance replacement rotor engineered to deliver consistent stopping power and improved heat dissipation over stock rotors. Designed as a bolt-on upgrade, this rotor is precision-machined to OEM specifications for a hassle-free installation.

The slotted surface design continuously sweeps debris, brake dust, and gases away from the pad face during braking, maintaining a clean contact surface and reducing brake fade under repeated heavy use. This makes the RNC rotor an excellent choice for drivers seeking a noticeable improvement over standard smooth rotors without the additional aggressiveness of a drilled design.

Key Features:

• Slotted rotor design for improved gas and debris evacuation at the pad/rotor interface
• Precision CNC machined from high-carbon gray iron for consistent thickness variation and smooth braking
• Zinc dichromate finish on non-contact surfaces to resist corrosion and improve appearance
• Direct OEM replacement — no modifications required for installation
• Balanced and tested for vibration-free performance
• Part of R1 Concepts' RNC lineup, offering an upgrade over standard replacement rotors
