Coming soon to a tire-shredding video near you is this custom Subaru STI, built for Hoonigan member Travis Pastrana. Pastrana is taking over the Gymkhana series, and this STI marks a return to Hoonigan's roots — Ken Block drove a Subaru in the first two Gymkhana videos. Subaru is no stranger to the demands of rally racing, and this STI raises the bar. Partner Vermont SportsCar collaborated on the build, taking a production body and turning it into this radical creation. The body is made of raw carbon fiber with an aero package proven in the wind tunnel. A custom-built turbocharged boxer-four engine features a stainless hood dump exhaust that drives all four wheels with rally-style long-travel suspension. You'll be able to watch this monster Subaru in action in upcoming Gymkhana installments.
