Virtual tuning, colloquially known as 'chopping' or 'VTuning', is the 2D graphical modification of automobiles, with the use of raster graphics editing software. Modifications such as aerodynamic and aftermarket body-kits, wheels, front mount inter-coolers and carbon fibre body panels, as well as interior or race car modifications, are super-imposed on a stock image in order to increase its aesthetic appeal. Whilst some designs are realistic in nature, one of the reasons why virtual tuners chop is to try modifications that may not be technically feasible if translated to real life. Virtually tuned cars are the complete and comprehensive makeovers of ordinary cars.
