R1 Concepts 830-42045R DFC GeoPerf Drilled Slotted Brake Rotor with GEOMET Coating

The R1 Concepts 830-42045R is a cross-drilled and slotted performance brake rotor featuring a premium Geomet anti-corrosion coating. Manufactured by Dynamic Friction Company (DFC) under the R1 Concepts performance lineup, this rotor is engineered for drivers who demand upgraded stopping power without sacrificing everyday drivability.

The 830-series designation identifies this rotor as a fully drilled, slotted, and Geomet-coated unit — combining three key performance enhancements in a single rotor. It meets or exceeds OE specifications for a straightforward, direct-fit installation with no modifications required.

Key Features:

• Cross-Drilled Holes: Reduce heat buildup on the rotor surface during aggressive braking, improving fade resistance
• Diamond Slots: Continuously sweep the pad surface to remove brake dust, debris, and gases, preventing pad glazing and maintaining consistent bite
• Geomet Anti-Corrosion Coating: Premium silver Geomet finish protects the hub, hat, and inner vane structure from rust and corrosion for improved longevity and appearance
• OE-Quality Construction: Machined to OE specifications for direct fitment — no modification required
• Versatile Performance: Suitable for daily street driving, performance driving, and demanding use conditions
• DFC-Engineered: Produced by Dynamic Friction Company, a trusted manufacturer in the performance brake segment

When first installed, the rotor arrives fully coated in the Geomet silver finish. During the break-in process, the coating on the braking surface will wear away naturally as the pads seat, leaving the hub and vane structure protected. A proper bed-in procedure is recommended to maximize rotor and pad performance.
