Petty’s Garage will build a total of 300 highly modified Mustang GTs in three different versions with up to 727hp. 243 of these will be King edition fastback models, 43 King Premier fastbacks and 14 King Premier convertibles.

All these models are powered by the 5.0-liter engine boosted to 670hp thanks to a Ford Performance supercharger.

For those who want even more power, an optional level two upgrade offers 727hp thanks to a smaller supercharger pulley. The highly modified Mustang GTs are built to the specifications of NASCAR legend Richard “The King” Petty himself.

Based on the stock 2016 Ford Mustang GT, Petty’s Garage King edition adds a Ford Performance supercharger to the 5.0-liter V8 engine, boosting output by 235hp for a total of 670 horsepower. Other powertrain upgrades include custom engine calibration, a cold-air intake for better breathing and a MagnaFlow exhaust.

Modifications also include extreme-duty TrakPak Ford Performance halfshafts, three-way adjustable front and rear sway bars, and a rear axle upgrade. The custom Mustangs ride on matte-black Petty’s Garage/HRE staggered 20- x 9-inch front wheels and 20- x 10-inch rear wheels with Continental Extreme Performance summer tires.

Besides the performance parts, Petty’s Garage added styling upgrades such as a custom rear diffuser with Richard Petty-designed center-mounted exhaust, shift knob, sill plates, floor mats, embroidered head restraints and rear spoiler. In addition, the King’s signature is featured on a special dash plate on every model.

As for the King Premier edition, offered both as a Fastback and Convertible, changes include different HRE/Petty’s Garage wheels, a big brake upgrade kit that includes six-piston front brakes and four-piston rears over two-piece rotors, as well as custom leather trimmed interior.

Other highlights include a complete Petty’s Garage/BASF custom tri-color stripe package featuring iconic Petty blue, red and white stripes covered in crushed and tumbled glass in clear coat. Petty blue body cladding gets the clear coat crushed and tumbled glass as well.

Besides the 727hp supercharger upgrade, options for all three editions include different wheel bushings to minimize wheel hop and a coil-over racing suspension.

Prices start from $67,495 for the King edition and $90,495 for King Premier.
