Kartboy® is the brand name of All Wheel Engineering, LLC, founded in 1999 to supply the U.S. market with upgraded components for Subaru Impreza 2.5RS vehicles. With the addition of the Subaru WRX to the 2002 model line, the product line has expanded. Today, it includes a broad variety of products, ranging from short shifters, shifter bushings, and suspension bushings to endlinks for just about any Subaru model. In addition, the company acts as consultants to professional racing teams, which allows it to be involved with the manufacture of NHRA, IHRA, SCCA, IKF, IMSA chassis and engine development, and then use that experience to improve its own products.
