R1 Concepts 830-47039R Performance Brake Rotor Drilled Slotted with Geomet Coating

The R1 Concepts 830-47039R is a high-performance brake rotor engineered to deliver superior stopping power for automotive applications. This rotor features both cross-drilled holes and diamond slot technology to maximize braking performance, heat dissipation, and rotor longevity.

Key Features:

• Cross-drilled design reduces rotor heat buildup by up to 105°F for improved performance
• Diamond slot technology removes brake dust and road debris while preventing pad glazing
• GEOMET corrosion-resistant coating provides superior protection against rust and extends rotor life
• Countersunk drill holes prevent cracking and ensure structural integrity
• Manufactured from G3000 grade cast iron for optimal strength and durability
• Built to OEM specifications for direct-fit installation with no modifications required
• Non-directional finish promotes faster, more even brake pad bed-in

Performance Benefits:

The precision-drilled holes enhance ventilation and heat dissipation, while the diamond-shaped slots serve a dual purpose: they increase brake pad bite for improved stopping power and act as a wear indicator—when the diamond tips disappear, it's time for rotor replacement. The advanced GEOMET coating covers the hub and non-braking surfaces, maintaining a clean appearance while protecting against corrosion. During initial break-in, the coating on the braking surface will wear away where pads contact the rotor, which is normal and expected.

Ideal for daily driving, street performance, light towing, and off-road applications, this rotor delivers consistent, reliable braking performance with smoother and quieter stops compared to standard rotors.
