R1 Concepts 830-54066L Drilled and Slotted Performance Brake Rotor - Left Side

The R1 Concepts 830-54066L is a high-performance drilled and slotted brake rotor designed to deliver superior stopping power and enhanced heat dissipation. Part of the DFC GeoPerf series, this left-side rotor features advanced engineering to meet the demands of performance driving, towing, hauling, and daily use.

Key Features:

• Cross-drilled design reduces rotor temperatures by up to 105°F, preventing brake fade and maintaining consistent performance
• Diamond slot technology removes brake dust and road debris while preventing pad glazing for extended pad and rotor life
• Precision-drilled holes with countersunk design prevents cracking and enhances ventilation
• Manufactured from G3000 grade cast iron for exceptional durability, reliability, and stability
• Zinc plating finish provides superior corrosion protection and enhanced appearance
• Direct OEM fitment with no modifications required
• Diamond-tipped slot ends serve as a wear indicator for rotor replacement

This rotor combines the benefits of both drilled and slotted designs to maximize stopping power, durability, and performance. The cross-drilled holes improve cooling and wet-weather performance, while the diamond slots maintain optimal pad bite and extend component life. Ideal for street performance, light track use, off-road applications, and heavy-duty towing.
