That's what I've always thought and I checked the instructions last night and they said the only way to adjust ride height is by loosening the bottom locking ring and winding the bottom mount further up the threaded tube which I've done as much as possible, if the threaded tube was shorter it would solve my problem but I'm not about to drop £500 on a set of coilovers and then start hacking them up... I hope that's not the lowest they go at the rear.
