Why S550 Owners Love It

All you need is steady hands, a heat gun, and some cut-and-sand instrumentals. With a growing community of SHIROKAI Mustang owners asking for the next generation, we built this kit for S550 owners — and it became an absolute best seller. If there’s a Mustang with a SHIROKAI kit at a show, it gets attention and love. The wide fender flares let you run larger, aggressive wheels, and every panel follows the Mustang’s bodylines for an accurate, easier install. Build it for street or show — this wide body S550 setup gives your car a powerful, planted stance.
