R1 Concepts 830-55012R DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-55012R DFC GeoPerformance Drilled and Slotted Brake Rotor is a performance-grade disc rotor engineered for drivers who demand improved stopping power, heat management, and corrosion resistance over a standard OE replacement. Built by Dynamic Friction Company (DFC) under the R1 Concepts brand, this rotor combines cross-drilling, slotting, and a premium GEOSPEC corrosion-resistant coating in a single package.

Key Features:

• Cross-Drilled & Chamfered Holes – Drilled holes dissipate heat buildup during heavy braking; chamfered edges reduce the potential for stress cracking
• Machined Slots – Slots continuously sweep brake dust, gases, and road debris from the pad surface, preventing glazing and maintaining consistent bite — especially effective in wet conditions
• GEOSPEC Corrosion-Resistant Coating – A durable silver-gray finish applied to the entire rotor (including hat and vanes) that outperforms conventional paint and zinc coatings in rust resistance
• Ready to Install – Processed dry and shipped dry; no degreasing or additional preparation required before installation
• 100% Electronic Inspection – Every rotor is measured across more than 20 attributes at a dedicated inspection station to confirm OE-spec tolerances for runout, thickness variation, and surface finish
• OE-Matched Specifications – Engineered to meet or exceed original equipment dimensions and performance standards

The 830-55012R is sold as a single rotor. Confirm the required axle position (left or right) and quantity before ordering. For best results, replace rotors in axle pairs and perform a proper bed-in procedure after installation.
