In preparation for the 2015 SEMA show, Petty’s Garage kicked things into high gear, launching a series of new King Edition Mustang GT models that are guaranteed to knock the socks off ‘Stang fans every where. Petty’s Garage Mustang GT King Edition lineup includes 43 King edition models, 43 King Premier and 14 King Premier convertibles.

So there is something for everyone, and with up to 727 horsepower on offer, nobody’s going to complain that Petty’s Garage Mustang GT is all show and no go. The key to these cars’s astonishing power is a Ford Performance supercharger bolted on to the stock 5.0-liter V8 engine. It is good for an amazing 235 additional horsepower, but that only brings the total output to 670 horsepower in the diet models. The 700-hp version also features custom engine calibration, a cold-air intake and a MagnaFlow exhaust.

Then there is the design aspect in which Petty’s Garage Mustang GT King features, inside and out, custom rear diffuser with Richard Petty-designed center-mounted exhaust, shift knob, sill plates, floor mats, embroidered head restraints and rear spoiler. A set of matte black HRE rims in sizes 20- x 9-inch front wheels and 20- x 10-inch rear wheels complete the look. You can further customize the interior and exterior with the available options.

Other mechanical highlights of the PG Mustang GT include TrakPak Ford Performance halfshafts, three-way adjustable front and rear sway bars, and a rear axle upgrade.
