Ok you GQueers, how do you make a GU tougher?? Easy! lift and tyres. How do make a GQ tougher?? Not so easy, you need tyres, suspension lift, body lift, GU diffs, GU steering box and for the diesel boys GU injector pump, GU injectors and turbo set up. Yet from a distance if you put a GQ next to a 60 series they look pretty similar so how TUFF can your Q be if it looks like a cruiser???
