R1 Concepts 830-54309R DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-54309R is a DFC GeoPerformance drilled and slotted brake rotor engineered for drivers who want improved stopping performance over a standard OE replacement. Featuring a combination of cross-drilled holes and precision-cut slots, this rotor delivers enhanced braking bite, reduced heat buildup, and reliable performance in a wide range of driving conditions.

Key Features:

• Cross-Drilled & Chamfered Holes: Drilled holes reduce heat buildup on the rotor surface, while chamfering minimizes the risk of cracking under stress
• Precision Slots: Slots continuously sweep the pad surface to remove brake dust, road debris, and gases, preventing pad glazing and improving wet-weather stopping distance
• GeoSpec Corrosion-Resistant Coating: A durable silver-gray GeoSpec finish is applied to the entire rotor for superior rust and corrosion protection — far outperforming conventional paint or zinc coatings
• Ready to Install: The GeoSpec coating is processed dry and shipped dry, requiring no cleaning or additional preparation before installation
• 100% Electronic Inspection: Every rotor passes an electronic quality inspection measuring over 20 attributes to ensure OE-level specifications are met
• G3000/G11H18 Cast Iron Construction: Premium iron casting formulation engineered for strength, stability, and long-term durability
• Sold Individually: Quantity of one (1) rotor per package

The 830-54309R is part of the DFC GeoPerformance line, identifiable by its 830-series model prefix indicating a drilled, slotted, and Geomet-coated rotor. This disc brake rotor is an ideal upgrade for street performance, daily driving, and light spirited use where improved heat dissipation and consistent braking response are a priority.
