I think the only lift that X5 has is accomplished by the increased tire diameter. It doesn't look like the suspension has been raised at all. The other thing about those tires is that they will destroy the fenders and wheel liners over any bump especially while turning. Unless the bump stops have been seriously extended and the steering stops adjusted that thing will need major body work if it goes off road!
