R1 Concepts 830-54267L DFC GeoPerformance Drilled and Slotted Brake Rotor

The R1 Concepts 830-54267L is a high-performance DFC GeoPerformance brake rotor featuring both cross-drilled holes and diamond slotted design for maximum stopping power. Engineered for drivers who demand superior braking performance, this directional rotor combines advanced heat dissipation with enhanced pad bite for reliable, consistent braking in all conditions.

Key Features:

• Cross-drilled design reduces rotor temperatures by up to 105°F for improved heat dissipation and fade resistance
• Diamond slotted pattern removes brake dust and road debris while preventing pad glazing to extend rotor and pad life
• Premium GeoSpec coating provides superior corrosion protection throughout the entire rotor surface
• Constructed from high-quality G3000 grade cast iron for exceptional strength, stability, and durability
• Mill-balanced and precision-machined to OEM specifications for smooth, vibration-free operation
• Counter-sunk drill holes reduce the potential for cracking and ensure proper bedding
• Diamond-tipped slot ends serve as a wear indicator for rotor replacement
• Ships dry and ready to install without cleaning—saving installation time
• Directional design optimized for left side installation (driver side on most vehicles)

Dynamic Friction Company rotors are manufactured under the R1 Concepts corporate umbrella and undergo rigorous quality control, with each rotor passing a 100% electronic inspection measuring over 20 attributes to ensure OE specifications are met. The advanced GeoSpec finish is processed dry and eliminates the need for pre-installation cleaning, reducing brake job time by up to 30 minutes per axle. Ideal for daily driving, street performance, light towing, and weekend track use.
