just a newbie question

hello guys, sorry to ask what will be a silly question for you but is it possible to buy extensions for the wheels arches or is it the case of getting the arches rolled. if it is a case of extensions where would i go about gettin them. cheers lads and ladies

berg do an enlarged arch kit but it is very wide. rolling the arch wont extend then out on a golf because of the existing flare it can stop rubbing though.
