Kartboy

 Kartboy also known as All Wheel Engineering, LLC was founded in 1999 to serve the U.S. market demand for aftermarket Subaru 2.5 RS platforms. At that time, products were being imported from Japan to the UK at a high cost. All Wheel Engineering then started production stateside and developed short shifter kits, bushing kits, which today have been a leading source for high quality drivetrain products for several Subaru models.
