Originally designed for professional racing teams competing in the IMSA Continental Tire SportsCar Challenge Grand Sport (GS) class, the Forgeline GS1R-CL combines the latest in advanced wheel technology, including 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 and exceptional deflection stiffness.
The GS1R-CL is machined from a single forging of 6061-T6 aluminum. It is currently available in 17, 18, 19, 20, and 21-inch diameters with a range of widths and offsets. It can be made to accommodate most centerlock applications and can be made with knurled beads. And just like any Forgeline wheel, the GS1R-CL is available with fully customizable finish options.
