The R1 Concepts WBPN1-03040 is a GEO-Carbon Series cross-drilled and diamond-slotted performance disc brake rotor engineered for demanding street and daily driving applications. Built to OEM fitment specifications, this rotor installs without modification for a straightforward replacement experience.

Key Features:

• GEO-Carbon Construction: Cast from G3000-grade high-carbon iron with increased carbon, molybdenum, and chromium content for superior strength, heat dissipation, and noise dampening
• GEOMET Protective Finish: Specialty corrosion-resistant coating provides long-lasting rust protection and dramatically reduces installation prep time compared to uncoated rotors
• Cross-Drilled Design: Precision-drilled holes with countersunk edges reduce heat buildup, enhance ventilation, and prevent cracking under repeated hard stops
• Diamond Slotted Pattern: Increases brake pad bite, extends pad life, and acts as a visual wear indicator to alert you before the next service interval
• Mill-Balanced: Each rotor is precision mill-balanced to ensure smooth, vibration-free braking performance
• Direct OEM Replacement: Engineered to match OEM specifications — no modifications required for installation
