Designed for professional racing teams competing in the IMSA WeatherTech GS class, the Forgeline GS1R combines the latest in advanced wheel technologies: one-piece forged monoblock construction, motorsport engineered design, and I-beamed spokes. This wheel is engineered to withstand the rigors of top-level endurance racing with a 2100-lb. street tire load rating, exceptional deflection stiffness, and very light weight.
Made from the same forgings and similar design as the popular GA1 street wheel, the GS1R has more material machined from the center area for additional weight reduction and improved access to the lugs. In combination with a new chamfered outer lip (with fewer sharp edges for easier handling), this open-lug design enables faster wheel changes and saves up to an additional pound of mass from each wheel.
The GS1R is currently available in 17, 18, 19, and 20-inch diameters with a range of widths and offsets. And just like any Forgeline wheel, the GS1R is available with fully customizable finish options.
