Similar to the original road racing version of the GS1R, the new 18×5 inch “Skinny” version of the one piece forged monoblock GS1R is precision-machined from a single forging of proprietary 6061-T6 aluminum alloy. But unlike the original road racing version, the “Skinny” has been re-engineered to be optimized for drag racing applications. This includes not only the narrower width (which necessitates a unique narrow forging), but a full set of revised performance metrics to make the 18×5 inch GS1R “Skinny” as lightweight as possible.
In addition to the 18×5 inch “Skinny” GS1R’s size and weight advantages, it also retains the exceptional brake clearance of the original GS1R. Which means that recreational straight line racers can maintain the giant front brake kits that came with their sports cars, which allows unprecedented flexibility for a wide range of motorsport endeavors.
Like all Forgeline wheels, the new 18×5 inch one piece forged monoblock GS1R “Skinny” is custom made-to-order and each unique vehicle application.
