This means both the clutch pressure plate and the fly wheel will wear un-evenly due to more friction toward the outer edge of the mating surface. If the pressure plate and flywheel are "dished" enough, a nice parallel clutch disk will not be squeezed evenly, and there will be trouble. There is probably a tolerance for this, but I do not know what it is. The more action your clutch has had, the more likely that the steel parts need attention, too. Tim Dapper
