R1 Concepts 631-92006R RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92006R RNC Series Drilled and Slotted Brake Rotor delivers a meaningful performance upgrade over stock rotors, combining cross-drilled holes and diamond slot technology in a direct-fit, OEM-spec replacement design. Built from G3000 grade cast iron with a zinc plated finish, this rotor resists corrosion while providing reliable, consistent stopping power for daily driving, street performance, towing, and light off-road use.

Key Features:

• Cross-Drilled Design: Precision-drilled, chamfered, and countersunk holes reduce rotor surface temperatures by up to 105°F, improving heat dissipation and reducing brake fade
• Diamond Slot Technology: Slots clear brake dust, gas, and road debris from the pad surface to prevent glazing and extend pad life; diamond-tipped slot ends double as a rotor wear indicator
• G3000 Cast Iron Construction: High-grade iron casting provides excellent strength, stability, and braking consistency across a wide range of driving conditions
• Zinc Plated Corrosion Protection: Silver zinc coating protects the hat, hub, and vane areas from rust; braking surface coating naturally wears away during the bed-in process
• Direct OEM Fit: Engineered to factory specifications for a straightforward installation with no modifications required
• Versatile Performance: Suitable for daily commuting, street performance, towing/hauling, and light off-road applications

A proper break-in procedure is recommended after installation to achieve optimal pad transfer and maximum braking performance. Always replace brake pads when installing new rotors for best results.
