R1 Concepts 633-92098L RNC Series Drilled & Slotted Brake Rotor - Left

The R1 Concepts 633-92098L RNC Series Brake Rotor is a precision-engineered drilled and slotted performance disc brake rotor designed as a direct-fit replacement that delivers enhanced stopping power over standard OEM rotors. This is a single left-side (driver-side) rotor built to OEM specifications for a no-modification, bolt-on installation.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes improve heat dissipation and ventilation, while the slots channel away gases, dust, and debris to maintain consistent brake pad contact and bite
• G3000 Grade Cast Iron Construction: High-quality cast iron blank provides the strength, durability, and thermal stability required for reliable performance under demanding driving conditions
• Zinc Dichromate Finish: Protective zinc coating on non-contact surfaces prevents rust and corrosion, keeping the rotor looking clean and extending service life
• Diamond Slot Technology: Precision-cut slots remove brake debris and prevent pad glazing, extending the life of both the pad and rotor
• OEM-Spec Fitment: Engineered to match original equipment dimensions and specifications — no modifications required for installation
• Left Side (Driver Side): This listing is for a single left/driver-side rotor (suffix -L)

R1 Concepts RNC Series rotors are an excellent upgrade for drivers seeking improved braking performance for daily driving, street performance, light towing, or spirited road use. The drilled and slotted surface reduces brake fade during repeated or high-speed stops, making this rotor a reliable and cost-effective alternative to OEM replacement parts.
