Jason Bos is a machinist by trade. So when it came to building a custom ride, Bos was right at home. Once he acquired some new tools and began learning new techniques, there was no limit to what he could do. In addition to a custom set of wheels, the world's only 3-piece RPF1s, Bos has gone through every part of his 2003 VW GTI and transformed the car.

FAVORITE MODIFICATION:
"Wide body fenders because it makes the car stand out from the rest. No MK4 Golf has ever done this look. It emulates a time attack or hill climb car. The most work went into making the fenders and I learned so many new skills and used many different machines to create them."
FUTURE MODIFICATIONS:
"Rear diffuser which I have already designed. Just need to send out for waterjet and forming. It will complete the look of the car, as well as custom carbon aero accents at the side skirts meeting the fenders. It will all be custom in house."
