The Espionage doesn't actually wear an authentic Mustang body, but RIngbrothers instead builds the coupe around its carbon fiber replacement. The switch sheds significant weight from stock, and this version also widens the car by four inches to fit some meaty rubber underneath. The broad shoulders are subtle at first but become more obvious the longer the guys check out this fantastic custom.
The Brothers are also quick to joke about a secret that hides under the hood. Rather than a Ford V8, there's a supercharged Chevy in there. It might seem like automotive blasphemy, but the odd choice comes at the request of the Espionage's buyer. Ringbrothers estimates the mill churns out 950 horsepower, and the engine absolutely roars once Jay takes it for a ride. Take the full tour with the guys in the video, and find out what other tricks this coupe hides.
