This Mustang of the Moment goes to altjx (Alton) and his 2015 Mustang GT convertible. Alton may be new to Mustangs, but you could not tell from his list of modifications.
With a Roush Performance complete fascia kit, hood scoop, rocker winglets, side scoops and heat extractors, this S550 not only looks the part, but it has the muscle to back it up. The Roush Phase 1 supercharger kit and tune helps it pump out 552RWHP.
