R1 Concepts 633-65013L RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 633-65013L RNC Series Drilled and Slotted Brake Rotor is a performance-grade replacement rotor engineered for drivers who demand superior stopping power and consistent fade resistance. Combining cross-drilled holes and precision-machined slots, this rotor maximizes heat dissipation and gas evacuation to keep braking performance sharp under demanding conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and improve heat venting, while machined slots continuously clean and deglaze brake pad surfaces for consistent bite
• Premium G3000 Metallurgy: Cast from high-carbon G3000 grade iron for excellent thermal stability, reduced noise, and long service life
• Zinc Dichromate Coating: Non-friction surfaces are coated to resist rust and corrosion, maintaining a clean appearance and preventing premature surface degradation
• Precision Balanced: Computer-balanced to OEM tolerances to minimize vibration, brake pedal pulsation, and lateral runout
• Direct OEM Replacement: Engineered as a direct bolt-on replacement — no modifications required
• Left-Side Fitment (L): This is the driver-side (left) rotor; verify vehicle fitment before installation

R1 Concepts rotors undergo rigorous quality control and dimensional verification to ensure they meet or exceed original equipment specifications. The RNC series is an ideal upgrade for daily drivers and performance enthusiasts looking for improved braking response and durability over standard OEM rotors.
