R1 Concepts 631-31146D RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-31146D RNC Drilled and Slotted Brake Rotor delivers enhanced stopping power and fade resistance for drivers who demand more from their braking system. Engineered with a precision cross-drilled and slotted surface pattern, this rotor promotes superior heat dissipation, reduces brake fade under repeated or aggressive braking, and helps clear gas, dust, and debris from the pad contact surface.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and improve heat venting, while machined slots continuously clean and refresh the brake pad surface for consistent bite
• RNC (Rounded Narrow Corners) Slot Pattern: R1 Concepts' proprietary slot geometry minimizes pad edge cracking and chipping while maximizing rotor longevity
• Premium G3000 Metallurgy: Cast from high-carbon G3000 iron for optimal thermal capacity, noise reduction, and durability
• Zinc Dichromate Coating: Non-friction surfaces are coated to resist rust and corrosion, keeping the rotor looking clean and performing reliably
• Precision Balanced: Computer-balanced to OEM-equivalent tolerances for smooth, vibration-free braking and minimal pedal pulsation
• Direct OEM Replacement: Designed to bolt on without modification, using factory mounting points and hardware

The R1 Concepts 631-31146D is an ideal upgrade for drivers seeking improved braking performance over a standard OEM rotor, whether for daily driving, spirited road use, or light track duty. Each rotor is individually inspected to meet strict quality standards before leaving the factory.
