The Forgeline GS1R-6 is designed for professional racing teams competing in the IMSA Continental Tire SportsCar Challenge Grand Sport (GS)—combining advanced wheel technology and motorsport design to deliver lightweight performance with exceptional deflection stiffness.

Engineered for top-level endurance racing with a 2100+ lb. street tire load rating, the GS1R-6 has significant material machined from the center for additional weight reduction and improved access to lug nuts. It features I-beamed spokes and a new chamfered outer lip for easier handling.

The GS1R-6 is designed specifically for vehicle applications with 6-lug hubs, including the Dodge Viper.

Compared to our original GA1R street wheel, the GS1R can save an additional pound of mass per wheel depending on the size and offset and enables faster wheel changes.

If you wish to use the optional Open Lug Center Caps, please specify in your order as the GS1R-6 requires special machining to ensure a proper fit.

The GS1R-6 is a one-piece monoblock wheel, precision-machined from a single forging of 6061-T6 aluminum.

Custom Fitments

CUSTOM FITMENTS,
TAILORED TO YOUR CAR

All Forgeline wheels are custom made-to-order. That means we engineer and build every set of wheels from scratch one at a time to match your vehicle specifications and intended application. From custom size, lug pattern, and backspace/offset, we can create the perfect fitment for your build.

Custom Finishes

CUSTOM FINISHES
TO FIT YOUR STYLE

We finish every wheel by hand. It starts with the labor-intensive hand-grinding, sanding, and inspection process. From there, we hand-apply a high-quality powder coat that's more consistent and durable than any mass-produced alternatives. Choose virtually any color for your wheels.

Made in USA

CUSTOM WHEELS,
MADE IN THE U.S.A.

We manufacture every Forgeline wheel at home in Dayton, Ohio. Down to the raw aluminum forgings, we source the best materials and parts from trusted companies that we believe make the best products. Why? So you can be confident knowing that you're getting the highest quality wheels possible.
