R1 Concepts 613-40007L RNC Series Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-40007L RNC Series Slotted Brake Rotor is a direct-fit replacement rotor engineered for improved braking performance over standard OEM rotors. Featuring a slotted rotor face design, this rotor continuously sweeps debris, gas, and brake dust away from the pad surface during braking, helping maintain consistent contact and reducing brake fade under demanding conditions.

Manufactured from high-quality G3000 gray iron casting, the RNC rotor meets or exceeds OEM dimensional specifications for a precise, no-modification installation. Each rotor is precision-machined and balanced to minimize vibration and pedal pulsation. The left-side designation ("L" suffix) ensures proper fitment for the driver-side wheel position.

Key Features:

• Slotted rotor design – evacuates heat, gas, and debris from the pad contact surface for consistent braking
• G3000 gray iron construction – meets OEM material standards for durability and thermal performance
• Precision machined – balanced to minimize vibration, pedal pulsation, and noise
• Direct OEM replacement – no modifications required for installation
• Left/driver-side fitment – designed specifically for the driver-side wheel position
• Zinc wash coating – helps protect rotor surface during shipping and initial use

The R1 Concepts RNC slotted brake rotor is an ideal upgrade for drivers seeking improved braking responsiveness and longevity compared to standard smooth-faced OEM rotors, without the added cost of a fully drilled and slotted design.
