Forgeline Carbon+Forged wheels combine weight-optimized CNC-machined forged aluminum centers with Emergent’s revolutionary proprietary carbon fiber barrels to deliver the ultimate in technological advancement, exclusive styling, and unparalleled lightweight performance. Custom, made-to-order, precision-machined 6061-T6 aluminum centers allow the flexibility to create unique style and finish options and to accommodate a wide variety of vehicle fitments. And the super-lightweight carbon fiber barrels utilize a high-density carbon fiber bundle, high-clarity resin system, and large carbon weave to create an attractive and visually distinctive rim that is 42% lighter than its aluminum equivalent, delivering a significant weight reduction to the wheel's outer perimeter, where it has the greatest reduction in unwanted inertia and yields real-world improvements to acceleration, braking, cornering traction, ride quality, NVH (noise, vibration, & harshness), driver/passenger comfort, and fuel economy.
