R1 Concepts 830-03021R Drilled and Slotted Performance Brake Rotor

The R1 Concepts 830-03021R is a high-performance brake rotor featuring cross-drilled and diamond slotted design for maximum stopping power and heat dissipation. Part of the DFC GeoPerf series, this rotor combines advanced engineering with superior corrosion protection to deliver reliable braking performance for street, performance, and demanding driving applications.

Key Features:

• Cross-drilled holes reduce rotor temperature by up to 105°F and improve wet weather braking
• Diamond slot technology removes brake dust and road debris while preventing pad glazing
• Constructed from G3000 grade cast iron for superior strength, stability, and durability
• Geomet coating provides advanced corrosion protection for extended rotor life
• Countersunk drill holes prevent cracking and ensure smoother pad bed-in process
• Diamond-tipped slot ends serve as wear indicators for replacement timing
• Direct OEM fitment requires no modifications for quick installation

This rotor is engineered to deliver consistent braking performance across daily driving, light track use, towing, hauling, and off-road conditions. The Geomet protective coating guards against rust and corrosion while maintaining an attractive appearance. Manufactured to precise OEM specifications for reliable direct-fit installation.

Note: Rotors arrive fully coated with protective silver Geomet finish. During the initial break-in period, the coating on the braking surface will wear away where pads contact the rotor, leaving only the hub and inner vane structure coated for ongoing corrosion protection.
