R1 Concepts 830-55004R DFC GeoPerf Drilled Slotted Performance Brake Rotor

The R1 Concepts 830-55004R DFC GeoPerf Drilled and Slotted Brake Rotor is a high-performance direct-fit replacement rotor engineered for drivers who demand superior stopping power and fade resistance. Designed as part of R1 Concepts' GeoPerf series, this rotor combines precision drilled holes and geometrically optimized slots to maximize thermal dissipation and bite under both street and performance driving conditions.

The cross-drilled holes allow heat, gas, and debris to escape from the rotor face, while the precision-cut slots continuously clean and deglaze brake pad surfaces for consistent, confident braking. The rotor is manufactured from high-carbon G3000 gray iron for durability and noise-free performance, and features a zinc dichromate coating on non-friction surfaces to resist corrosion and maintain an attractive appearance.

Key Features:

• Drilled and slotted GeoPerf rotor design for enhanced heat dissipation and pad bite
• High-carbon G3000 gray iron construction for strength, durability, and quiet operation
• Zinc dichromate anti-corrosion coating on non-swept surfaces
• Precision-balanced to minimize vibration and pedal pulsation
• Direct OE replacement — no modifications required for installation
• Exceeds OEM dimensional and metallurgical specifications
• Ideal for street performance, spirited driving, and light track use

The R1 Concepts GeoPerf series is a popular upgrade over standard OE rotors, offering improved thermal performance and a sportier appearance without sacrificing daily drivability. This rotor is a direct bolt-on replacement, making installation straightforward for both professional technicians and experienced DIY enthusiasts.
