Lowering 2001 X5 4.4

[jst2878]

wHAT HAVE X5 MEMBERS BEEN USING TO LOWER THEIR X5 BUT NOT COMPROMISE THE INTEGRITY OF THE RIDE. i AM CONSIDERING LOWERING MY 2001 X5 WITH REAR AIR SUSPENSION. wHAT COMPANY MAKES A 2.5INCH DROP FOR THE FRONT(COILOVERS PREFERRED) i UNDERSTAND THAT i NEED CAMBER PLATES FOR THE FRONT ALIGNMENT BUT WILL i NEED NEW,SHORTER REAR CONTROL ARMS WHEN i LOWER THE BACK VIA DIS? wOULD i BE ABLE TO USE ARMS FROM A 2004 SPORT MODEL? oR WILL AN ALIGNMENT STRAIGHTEN THE CAMBER FOR THE REAR WITHOUT ANY MAJOR CHANGES? cOULD i USE THE FRONT SUSPENSION OFF A 2ND GENERATION BMW WITHOUT AIR SUSPENSION OR WILL THE RIDE HEIGHT BE THE SAME AS MY ORIGINAL HEIGHT.
