The Forgeline GS1R-CL is a center lock version of our legendary GS1R wheel, which is designed for professional racing teams competing in the IMSA Continental Tire SportsCar Challenge Grand Sport (GS).
Engineered for top-level endurance racing with a 2100+ lb. street tire load rating, the GS1R-CL has significant material machined from the center for additional weight reduction and improved access to lug nuts.
The GS1R-CL features I-beamed spokes, a new chamfered outer lip for easier handling, and optional knurled beads. It can be made to fit most center lock applications.
Compared to our original GA1R street wheel, the GS1R-CL can save an additional pound of mass per wheel depending on the size and offset and enables faster wheel changes.
The GS1R-CL is a one-piece monoblock wheel, precision-machined from a single forging of 6061-T6 aluminum.

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
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.
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.
