R1 Concepts 631-92085R RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92085R RNC Series Drilled & Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver superior stopping power and heat dissipation over standard OEM rotors. Designed for drivers who demand more from their braking system, this rotor features a combination of cross-drilled holes and precision-cut slots that work together to evacuate heat, gas, and debris from the rotor surface.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and dissipate heat rapidly, while the machined slots continuously clean and deglaze brake pad surfaces for consistent bite and fade resistance
• Premium G3000 Metallurgy: Manufactured from high-grade G3000 iron alloy for excellent thermal stability, durability, and long service life
• Zinc Dichromate Coating: Protective anti-rust coating on non-friction surfaces helps prevent corrosion and maintains a clean, finished appearance
• OEM-Equivalent Fit: Engineered to match original equipment dimensions for a direct bolt-on installation with no modifications required
• Computer Balanced: Each rotor is precision machined and balanced to minimize vibration and pedal pulsation during braking
• Vented Construction: Internal vane venting promotes continuous airflow through the rotor to manage heat buildup under demanding driving conditions

R1 Concepts rotors are manufactured to meet or exceed OEM specifications and are a direct replacement for worn or warped factory rotors. The RNC series is an excellent upgrade for daily drivers and performance-oriented vehicles looking for improved braking response without sacrificing street driveability.
