hey guys! a buddy of mine just got an 07 X5 and he put some 22's on it. and im sure ill get flamed a bit for this thread but just trying to help a buddy out

.
he doesnt go off road or anything obveously with the 22's, but he got the truck as a type of nice family car, and needs to be able to haul stuff from time to time.
i think that if we could low it about 2 inches it would be perfect.
any ideas? segestions?
Thanks guys!
