FORGELINE GS1R COMPETITION WHEELS

MATTE RED finish

Originally designed for professional racing teams competing in the IMSA Continental Tire SportsCar Challenge Grand Sport (GS) class, the Forgeline GS1R combines the latest in advanced wheel technology, including one piece forged monoblock construction, motorsport engineered design, and I-beamed spokes. This wheel is engineered to withstand the rigors of top-level endurance racing with a 2100 lb street tire load rating and exceptional deflection stiffness.

Though made from the same forgings and similar design as our original GA1R street wheel, the GS1R employs an open-lug center area for additional weight reduction and improved access to the lugs. In combination with a new chamfered outer lip (with fewer sharp edges for easier handling), this enables faster wheel changes and, depending on size and offset, can save an additional pound of mass from each wheel!

The GS1R is machined from a single forging of 6061-T6 aluminum.

Forgeline Motorsports manufactures the world’s finest premium forged aluminum custom performance racing wheels for the most discerning enthusiasts and the most demanding applications.

Forgeline wheels are machined from heat-treated 6061-T6 aluminum that is forged on a 6000-ton hydraulic press. This forging process aligns the grain structure, reduces porosity, and increases uniformity in the material, creating the highest strength-to-weight ratios and the most consistent quality. On average, our forgings are 40% stronger than cast aluminum.
