Forgeline GS1R-CL Monoblock Forged Wheel

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.
