Shelby American has announced its new upgrade kit for the next-generation Ford Mustang boasting a monstrous supercharger that'll get you 625+hp. The 2015 Shelby GT adds an array of lightweight carbon fiber components which include the hood, rockers, splitter, and rear diffuser. All those parts can be painted or left exposed in its raw state. 

The standard model will feature the 625+hp supercharger, custom Borla exhausts by Ford Racing, and half shafts and a handling pack also by Ford Racing. The front brakes also get upgraded with Wildwood 6 pistons and the tire setup features Michelins and wheels by WELD Racing. If the 625+hp package isn't enough for you, there's also an optional 700+hp upgrade available as well. 

The Shelby GT upgrade starts at $39,995 (on top of base vehicle) and is now available from ShelbyAmerican.com.
