Forgeline GS1R Skinny Monoblock Forged Wheel
Couldn't load pickup availability
The GS1R Skinny is an 18×5 inch wheel derived from our road racing GS1R wheel—re-engineered for drag racing applications.
Featuring the same track-proven design, the GS1R Skinny is narrower in width and has been designed with new performance metrics that make the wheel as lightweight as possible.
The GS1R Skinny retains generous caliper clearance for extreme brake fitment so you can swap these onto your modern sports cars and have ultimate flexibility for a wide range of motorsport endeavors.
Unlike most traditional drag racing wheels, the GS1R Skinny is a one-piece monoblock wheel, precision-machined from a single forging of 6061-T6 aluminum.
