R1 Concepts 830-00004R DFC GeoPerf Drilled Slotted Brake Rotor with GeoSpec Coating

The R1 Concepts 830-00004R is a DFC GeoPerformance Drilled and Slotted Brake Rotor featuring a premium GeoSpec corrosion-resistant coating. Engineered for drivers who demand enhanced stopping performance beyond stock, this rotor combines cross-drilled holes and slots to deliver improved thermal management and consistent braking response in a wide range of driving conditions.

Key Features:

• Cross-Drilled Holes: Reduce heat buildup on the rotor surface during heavy or repeated braking, helping maintain consistent pad bite and pedal feel
• Slotted Surface: Continuously sweeps away brake dust, gases, and road debris from the pad contact area, preventing glazing and maintaining a clean bite surface
• GeoSpec Corrosion-Resistant Coating: Applied to the entire rotor including hub and vane structure, delivering a durable silver-gray finish that outperforms conventional paint or zinc coatings
• Dry-Processed & Installation-Ready: The GeoSpec coating ships dry with no oily residue — no pre-cleaning required before installation, saving time during the brake job
• OE-Matched Engineering: Each rotor is engineered to match OE vane configuration, including split-core technology for proper heat dissipation
• 100% Electronic Inspection: Every rotor passes a multi-point electronic inspection measuring over 20 attributes to ensure it meets OE dimensional specifications
• Right Side (R): This is the right-side rotor — verify fitment for your specific axle position

The DFC GeoPerformance series is designed to handle everyday street driving as well as more demanding use including spirited driving and track days. The 830-series designation confirms this rotor features the full Drilled + Slotted + GeoSpec treatment for maximum performance and corrosion protection in a single package.
