Prior Design has a solid reputation for adding aggressive styling to the latest sports cars and supercars, and it's latest project is based on the Mercedes-AMG GT S. Dubbed the PD800GT widebody kit, the styling package adds front and rear trunk spoilers, air intake surrounds and canards, new aerodynamic side-skirts, a rear diffuser, a new ventilated hood, and front/rear widenings and cupwings. No mods have yet to be made to the 503-hp 4.0-liter twin-turbo V8.
