Originally a customer modified race car, this 2005 Subaru WRX was built with one goal in mind: To become the world’s fastest standing half-mile Subaru WRX. We achieved that goal back in 2016 with a run of 183mph and have since surpassed it many times over. Our current record is 203mph achieved at ShiftS3ctor ”Motovicity Neverlift” 2019 at Coalinga Municipal Airport. This feat was achieved while missing 4th and 5th gear inside the transmission after an earlier gearbox failure. Since then this race car has been used for various R&D purposes, auto racing, as well as a quarter mile drag car. Current best quarter mile: 8.75 @ 170mph current all wheel horsepower 1200hp.
This project is ever evolving as we push the envelope on the Subaru platform. That being said, here is a basic list of what it takes in Subaru aftermarket parts to build a car of this caliber to become the fastest Subaru. Add about a thousand hours of labor and testing and you too can have a 200mph Subaru!
