I live in Australia and am planning to lower a 2006 std 530d. From what I read from the forum, most people would recommend either Eibach or H&R springs which reduce the height of about 30mm. Since I already have a body kit on the car, I like to lower it to about the same height to the M-sport version. I wonder if it will work with swapping in A)just a set of genuine/OE M-sport springs; a set of genuine/OE M-sports springs and shocks; or C)it cannot be done at all.

Any other suggestion are welcomed. Thanks.
