It s hard to out muscle a mustang, and this 2007 Tjaarda Mustang complete with supercharger, side exhaust, oversize Baer brakes and a modified suspension does not make it any easier. Used in the Fast and Furious 4 as the hero car the Universal team borrowed the car from a company called HST International. Moreover, HST also supplied the production team with two Mustang GTs that were modified to look like Tjaardas but where otherwise untouched mechanically (these where used as stunt cars). For the scene in which the car is destroyed an old beat up Mustang V6 was retrofitted to look like the Tjaarda. Who says that cars can t have stunt doubles?
