R1 Concepts 631-31148L RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-31148L RNC Series Brake Rotor is a performance-grade drilled and slotted replacement rotor engineered to deliver superior stopping power over standard OEM rotors. Designed for drivers who demand more from their braking system, this rotor combines precision machining with enhanced thermal management features.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes and machined slots work together to evacuate heat, gas, and brake dust from the rotor surface, maintaining consistent pad contact and reducing brake fade under demanding conditions
• Zinc Dichromate Coating: Protective coating on non-contact surfaces resists rust and corrosion, keeping the rotor looking clean and extending its service life
• Precision Balanced: Computer-balanced construction minimizes vibration and pedal pulsation for smooth, confident braking
• Direct OEM Replacement: Engineered to match OEM specifications for straightforward installation with no modifications required
• Left-Side Application: This part number (631-31148L) is specifically the driver-side (left) rotor
• Premium G3000 Grade Iron: Cast from high-quality metallurgy for long wear life and consistent performance

R1 Concepts brake rotors are manufactured to strict quality standards, making the 631-31148L an ideal upgrade for performance-minded drivers looking to improve braking response and heat dissipation over a stock replacement rotor.
