R1 Concepts 830-66001R DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-66001R DFC GeoPerf Drilled & Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand superior stopping power and fade resistance. Combining precision drilled holes with machined slots, this rotor promotes rapid heat dissipation, improved gas venting, and consistent bite throughout the braking zone.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and dissipate heat, while slots sweep away debris, gas, and brake dust for a cleaner, more responsive contact surface
• GeoPerf Technology: R1 Concepts' proprietary geometric slot and drill pattern optimized for maximum thermal performance and braking consistency
• Premium G3500 Metallurgy: Cast from high-carbon iron alloy for improved strength, reduced vibration, and extended service life compared to standard rotors
• Zinc Dichromate Coating: Corrosion-resistant coating on non-swept surfaces protects against rust and keeps the rotor looking sharp on the vehicle
• OEM-Matched Fitment: Engineered to OEM specifications for direct bolt-on installation with no modifications required
• Balanced Construction: Computer-balanced to minimize runout and prevent brake pedal pulsation or vibration

The R1 Concepts DFC GeoPerf rotor is an excellent upgrade for performance street driving, towing, or spirited canyon runs where standard rotors fall short. Paired with a quality performance brake pad, this rotor delivers confident, fade-resistant stopping in demanding conditions.
