Winner of the 2014 Scion Tuner Challenge is the Speedhunters FR-S, which according to Scion, “is a track day level racer that finds its inspiration of the early IMSA race days and the rise of Japanese racers in the United States.”

Unlike other Scion vehicles in the challenge, the Speedhunters FR-S is not outfitted with any name-brand third party body kits. Most exterior parts are customized and designed by Charvonia Design.

The interior is also customized and designed by Charvonia Design. Some noticeable interior additional aftermarket parts are 4pt Takata RACE 4 asm harness, Cusco roll cage, custom Cobra RS classic low back bucket seats, Raceseng shift knob and Grip Royal steering wheel.

Riding on 17-inch custom Rotiform BLQ wheels, the car is powered by the 2.0L 4U-GSE/FA20 Boxer engine with Cosworth Stage 2.0 supercharger kit, delivering 300 horsepower.  More detailed modifications below.
