R1 Concepts 633-32001L RNC Drilled & Slotted Brake Rotor

The R1 Concepts 633-32001L RNC Drilled & Slotted Brake Rotor is a performance-grade replacement rotor engineered to deliver superior stopping power and heat dissipation over the OEM equivalent. Designed as a direct bolt-on replacement, this rotor fits seamlessly into your existing brake system without modification.

Key Features:

• Drilled & Slotted Surface: Cross-drilled holes and machined slots work together to evacuate heat, gas, and brake dust from the rotor face, maintaining consistent pad-to-rotor contact and reducing brake fade under demanding conditions
• G3000 Metallurgy: Manufactured from high-grade G3000 grey iron casting for optimal thermal conductivity and long rotor service life
• Zinc Dichromate Coating: A protective zinc dichromate finish on the hat and non-swept areas helps resist corrosion and keeps the rotor looking clean under open-spoke wheels
• OEM-Matched Specifications: Precisely machined to OEM dimensions including diameter, thickness, and hub bore for a direct, no-modification installation
• Balanced & Computer-Tested: Each rotor is precision balanced and tested to minimize vibration and pedal pulsation

The RNC series from R1 Concepts is built for drivers who want a meaningful performance upgrade over stock rotors without stepping into a full racing brake kit. Whether used for spirited street driving or light track days, the 633-32001L provides reliable, fade-resistant braking performance. Sold individually as a single left-side rotor.
