Derived from our GTD1 racing wheel, the Forgeline GT1 brings its racing DNA to the street. The GT1 combines the latest in advanced wheel technology, including one piece forged monoblock construction, motorsport engineered design, I-beamed spokes, and I-beamed spoke spans to deliver head-turning good looks with track-ready capability.
The Forgeline GT1 is a fully-forged one-piece monoblock wheel. Utilizing manufacturing technology similar to our very successful GA1R wheel, the concave 12-spoke design of the GT1 looks great and allows plenty of room for caliper clearance and extreme brake fitment. The one-piece monoblock forging and computer-simulated FEA design process yield a wheel that is very lightweight, extremely stiff, and has excellent fatigue strength. The GT1 is engineered exclusively for Porsche center lock applications and is equipped with a special center lock to accommodate the Porsche Cup Car and RSR hub assembly.
The GT1 is machined from a single forging of 6061-T6 aluminum. It is currently available in 18, 19, 20, and 21-inch diameters. (Please Note: Depending on size, the GT1 may be available in deep, medium, or shallow concave profiles. See sizing chart for details.) And just like any Forgeline wheel, the GT1 is available with fully customizable finish options.
