R1 Concepts 830-40115R GEO-Carbon Drilled Slotted Brake Rotor

The R1 Concepts 830-40115R is a high-performance brake rotor from the GEO-Carbon Series, featuring both cross-drilled holes and diamond slot technology for maximum stopping power and durability. This rotor is engineered for drivers who demand superior braking performance across a wide range of driving conditions, from daily commuting to spirited driving, towing, and off-road use.

Key Features:

• Cross-drilled design reduces rotor heat buildup by up to 105°F and features chamfered, countersunk holes to prevent cracking
• Diamond slot technology removes brake dust and road debris while preventing pad glazing to extend pad and rotor life
• Premium corrosion-resistant coating protects the rotor surface for improved appearance and longevity
• Constructed from high-quality G3000 grade cast iron for exceptional strength, stability, and durability
• Built to OEM specifications for direct-fit installation with no modifications required
• Diamond-tipped slot ends serve as a wear indicator—when tips are worn away, rotor replacement is needed

The GEO-Carbon Series rotors provide superior heat dissipation and debris resistance, making them ideal for high-performance applications, heavy-duty towing, and demanding driving conditions. The special protective coating covers the entire rotor upon delivery; during the break-in process, the coating on the braking surface will wear away naturally while the hub and vane structure remain protected against corrosion.
