R1 Concepts 633-92095L RNC Drilled & Slotted Brake Rotor

The R1 Concepts 633-92095L is a single drilled and slotted brake rotor from the RNC series, engineered to deliver enhanced stopping performance over standard OEM rotors. Built to direct-fit OEM specifications, this rotor installs without modification for a straightforward replacement.

Key Features:

• Cross-Drilled Design: Precision-drilled and chamfered holes reduce rotor heat buildup and improve ventilation, helping prevent brake fade during demanding stops
• Diamond Slot Technology: Slots channel away brake dust, road debris, and gases to maintain consistent pad-to-rotor contact and prevent pad glazing — the diamond-tipped slot ends also serve as a built-in rotor wear indicator
• G3000 Grade Cast Iron Construction: High-grade cast iron provides excellent strength, stability, and long-lasting braking performance
• Zinc Plated Coating: A protective silver zinc plating is applied to the non-contact surfaces (hat, vanes, and edges) to resist corrosion and maintain appearance over time
• OEM Direct Fit: Engineered to original equipment specifications — no modifications or adapters required for installation
• Left-Side Position: This part number (633-92095L) is the left/driver-side rotor

Suitable for daily street driving, light performance use, towing, hauling, and off-road applications. As with all drilled and slotted rotors, a proper break-in (bedding) procedure is recommended after installation to ensure optimal braking performance and longevity.
