R1 Concepts 633-21020L Drilled and Slotted Brake Rotor Left Side

The R1 Concepts 633-21020L is a high-performance drilled and slotted brake rotor designed for the left side installation. This rotor combines cross-drilled and diamond slotted patterns to provide maximum benefits in stopping power, durability and performance.

Key Features:

• Formulated with G3000/G11H18 cast iron specification for durability, reliability, and stability
• Cross-drilled design reduces heat buildup on the rotor by up to 105° F
• Diamond Slot Technology removes brake and road debris and prevents pad glazing, extending the life of the pad and rotor
• Special zinc plating designed to protect from corrosion
• Non-directional finish promotes faster and more even disc brake pad bed-in, along with quieter and smoother stops
• Designed for direct fit with no modifications required

The diamond tipped slot ends provide an indicator for rotor replacement - when the tips are gone, rotor replacement is necessary. Ideal for daily driving, light track/rally, towing/hauling, off-road, and street performance applications. This left-side rotor is part of R1 Concepts' eLINE series, engineered to match OEM specifications while delivering enhanced braking performance and long-lasting reliability.
