R1 Concepts 830-72015R DFC GeoPerf Drilled Slotted Brake Rotor with GeoSpec Coating

The R1 Concepts 830-72015R is a DFC GeoPerformance drilled and slotted brake rotor featuring a premium GEOSPEC corrosion-resistant coating. Manufactured by Dynamic Friction Company (DFC) — a brand under the R1 Concepts corporate umbrella — this rotor is engineered for drivers who demand improved stopping performance over a standard OE replacement.

The combined cross-drilled and slotted design works together to maximize braking efficiency. The drilled holes dissipate heat that builds up on the rotor surface during repeated braking, while the chamfered edges on each hole reduce the potential for cracking under stress. The slots continuously sweep away brake dust, road debris, and moisture, preventing pad glazing and improving bite — particularly in wet-weather conditions.

Key Features:

• Cross-Drilled & Slotted Design — Reduces rotor heat buildup and removes brake debris to maintain consistent stopping power
• Chamfered Drill Holes — Reduces stress concentration at each hole to minimize cracking risk
• GEOSPEC Coating — Superior corrosion protection with a durable silver-gray finish that outperforms conventional paint or zinc coatings
• Ready to Install — Processed dry and shipped dry; no cleaning or additional preparation required before installation
• OE Vane Configuration — Engineered to match the OE split-core vane design for proper and maximum heat dissipation
• 100% Electronic Inspection — Each rotor measures over 20 attributes at a quality inspection station to ensure OE specification compliance
• Smooth Finish — Fine-turned to a maximum of 1.6 RMS for improved initial pad bed-in and contact

The GEOSPEC finish is applied to the entire rotor — including the hub and vane structure — providing long-lasting protection against rust and corrosion. Note: During the break-in process, the coating will naturally wear off the braking surface (pad contact area) while the hub and inner vane structure remain coated. This rotor is sold individually.
