Forgeline Wheels GS1R
Originally designed for professional racing teams competing in the IMSA Continental Tire SportsCar Challenge Grand Sport (GS) class, the Forgeline GS1R sets the standard in advanced wheel technology. Featuring one-piece forged monoblock construction, motorsport engineered design, and I-beamed spokes, the GS1R is engineered to withstand the rigors of top-level endurance racing. It carries a 2,100 lb. street tire load rating and exceptional deflection stiffness.
The GS1R has an open-lug center area, saving up to a pound in weight and improving access to the lugs. Combined with a chamfered outer lip this enables faster, easier wheel changes.
Forgeline Wheels GE1R
Derived from Forgeline's center-locking GE1R Porsche racing wheel, the GE1R 5-Lug brings that same style and performance to vehicles with traditional 5-lug hubs. The 8-spoke GE1R 5-Lug features 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 strength and capability.
The entire GE1R wheel is precision-machined from a single forging of proprietary 6061-T6 aerospace aluminum. Its concave design, tapered outer edge, and aggressive machining details make it look as good as it performs.
Forgeline Wheels VX1R
Combining the look of the popular VX1 with a load rating suitable for dedicated track duty, the VX1R is one of the most popular wheels for the GT4. It's a full track-ready competition wheel equal in strength to their famous GA1R and GS1R Motorsport Series wheels.
The VX1R features a sharp Y-spoke design with long spokes wrapping around the lug holes. Striking sharp angles, a deep concave profile, and chamfered outer edge, the VX1R exudes style. Beyond just good looks, the VX1R starts as a one-piece monoblock forging, and Forgeline's computer-simulated FEA design process results in a wheel that is lightweight and stiff with excellent fatigue strength.
Forgeline Wheels Come in an Array of Amazing Finishes
Your Forgeline Wheels Track Package can be finished in any of a wide array of colors, machined finishes, and tinted clear-coats. Powder coated for extraordinary durability, Forgeline Wheels on your Porsche look as good as they perform. Any standard finish is included in your Track Package, or you can upgrade to a dazzling premium finish!
