R1 Concepts 631-92036L RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92036L RNC Series Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver superior stopping power and thermal management over stock brake components. Designed as a direct OE-style replacement, this rotor installs without modification for a straightforward upgrade from your factory braking setup.

Key Features:

• Drilled and Slotted Design: Cross-drilled holes reduce heat buildup and unsprung weight, while machined slots sweep away gas, dust, and debris from the pad surface for consistent bite and fade resistance
• RNC Series Construction: Manufactured using premium G3000 metallurgy cast iron for a balance of strength, durability, and thermal conductivity
• OE-Quality Fit: Precision-machined to OEM specifications for direct bolt-on installation with no modifications required
• Corrosion-Resistant Coating: Non-contact surfaces feature a protective coating to resist rust and maintain a clean appearance
• Improved Cooling: The combined drill-and-slot pattern promotes airflow across the rotor face, reducing brake fade during demanding driving conditions
• Balanced Performance: Suitable for street and light performance driving, delivering an upgrade over standard OEM rotors without compromising daily drivability

The R1 Concepts 631-92036L is a left-side (driver's side) rotor, so be sure to pair it with the correct right-side counterpart when replacing in axle sets. Compatible with standard OEM-spec brake pads and calipers.
