R1 Concepts 830-54163R DFC GeoPerf Cross-Drilled Slotted Brake Rotor with GEOMET Coating

The R1 Concepts 830-54163R is a DFC GeoPerf Series cross-drilled and slotted brake rotor featuring a premium GEOMET corrosion-resistant coating. Engineered for drivers who demand improved stopping performance over a standard blank rotor, this right-side rotor delivers the combined benefits of drill and slot technology in a direct-fit, no-modification-required design.

Key Features:

• Cross-Drilled Holes: Precision-drilled and chamfered holes reduce heat buildup on the rotor surface and help prevent cracking, improving thermal performance under repeated hard stops
• Diamond Slot Technology: Slots evacuate brake dust, gas, and road debris from the pad-to-rotor contact surface, preventing pad glazing and extending the life of both the pad and rotor
• GEOMET Coating: Superior corrosion-resistant finish protects the hub, vanes, and non-swept surfaces from rust and oxidation, improving long-term appearance and reducing maintenance costs
• G3000/G11H18 Cast Iron Construction: Formulated to OEM iron grade specifications for strength, stability, and durability
• Double Disc Ground Braking Surface: Promotes faster, more even brake pad bed-in for quieter and smoother stops from the start
• Direct OEM Replacement Fit: Engineered to match OEM specifications — no modifications or adapters required for installation
• Right Side (R): This is a single rotor for the right side of the vehicle

The 830-series GeoPerf rotor is part of R1 Concepts' performance-oriented DFC lineup, designed for everyday street driving, performance driving, off-roading, and towing applications. The GEOMET finish applies a zinc-based coating that wears away naturally from the swept braking surface during the initial bed-in process, leaving corrosion protection where it matters most — the hub and inner vane structure.
