R1 Concepts 613-48090L RNC Series Slotted Brake Rotor

The R1 Concepts 613-48090L is a RNC Series slotted brake rotor engineered for drivers who demand consistent, reliable stopping power. Designed as a direct OE replacement with performance-enhanced slotting, this rotor delivers improved braking response and reduced brake fade compared to standard smooth rotors.

Key Features:

• Slotted Design: Precision-machined slots evacuate heat, gas, and debris from the rotor surface for cleaner pad contact and consistent bite
• OE-Spec Fitment: Engineered to match original equipment dimensions for a direct bolt-on installation with no modifications required
• High-Quality Iron Alloy Construction: Cast from premium iron alloy for excellent thermal capacity and long service life
• Zinc Dichromate Coating: Protective coating on non-friction surfaces resists corrosion and provides a clean, finished appearance out of the box
• Computer Balanced: Each rotor is balanced to minimize vibration and pedal pulsation during braking
• Left-Side Fitment: This part number is specifically designated for the left (driver) side

R1 Concepts rotors undergo strict quality control and are manufactured to meet or exceed OEM specifications. The slotted surface continuously cleans and deglazes brake pads, helping maintain optimal friction and braking efficiency over the life of the rotor.
