Disabling the ABS is "definitely" not a good idea....ABS is one of those things that you never really think that you need until you REALLY need it!. Further, some modern vehicles are "certified" by DOT with ABS being a part of the process, for reasons of design, and they do not meet federal safety standards with the ABS disabled......pickup trucks come to mind as a family of vehicles that will not meet the standards without operational ABS (at least on the rear wheels).
