R1 Concepts 631-92086L RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92086L RNC Series Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver superior stopping power, improved heat dissipation, and extended pad life compared to standard OEM rotors.

The combination of precision-drilled holes and machined slots work together to continuously sweep debris and gases away from the rotor surface, maintaining consistent pad-to-rotor contact for confident, fade-resistant braking performance under both everyday and demanding driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and aid in cooling, while slots channel away heat, gas, and brake dust for enhanced bite and feel
• High-Carbon Iron Construction: Premium metallurgy provides excellent thermal stability and resists warping under repeated heavy braking
• Precision Machined: Tight tolerances ensure proper fit and minimize vibration or brake pedal pulsation
• Corrosion-Resistant Finish: Zinc dichromate coating protects non-swept rotor surfaces from rust and corrosion for a clean appearance
• Direct OEM Replacement: Bolt-on fitment with no modifications required
• Left Side Application: Designed specifically for the left (driver's) side position

R1 Concepts rotors are manufactured to meet or exceed OEM specifications, making the 631-92086L a reliable upgrade for drivers seeking improved braking performance without sacrificing daily drivability. Each rotor undergoes rigorous quality control to ensure consistent performance and longevity.
