R1 Concepts 830-60008R GeoPerf Cross-Drilled & Diamond-Slotted Brake Rotor with Geomet Coating

The R1 Concepts 830-60008R GeoPerf Brake Rotor is a cross-drilled and diamond-slotted performance disc brake rotor finished with a premium Geomet corrosion-resistant coating. Engineered as a direct OEM replacement with a meaningful performance upgrade, this rotor is ideal for daily street driving, light track use, towing, hauling, and off-road applications.

Key Features:

• Cross-Drilled Design: Precision drill holes reduce rotor heat buildup by up to 105°F, are chamfered to minimize cracking risk, and are countersunk to allow a smoother bed-in process
• Diamond Slot Technology: Slots remove brake dust and road debris, prevent pad glazing, and extend the service life of both the rotor and brake pad — diamond-tipped slot ends also serve as a rotor wear indicator
• Geomet Finish Coating: Superior corrosion protection that outlasts standard zinc coatings, improving appearance and longevity while reducing long-term maintenance costs
• G3000 Grade Cast Iron Construction: Meets or exceeds OEM specifications for consistent thermal stability, braking power, and resistance to warping under demanding conditions
• Direct-Fit Replacement: Built to OEM dimensions for straightforward installation with no modifications required
• Right-Side Rotor: This listing is for a single right-side (passenger side) rotor

The 830-60008R is part of R1 Concepts' GeoPerf series — a cross-drilled and slotted rotor line with Geomet coating designed to deliver upgraded stopping performance over factory rotors without sacrificing daily drivability. A proper bed-in procedure is recommended after installation for optimal pad seating and rotor performance.
