Coilovers are overkill, IMO, and the KW's are the only way to go. I have an e70 X5 M as well and I bought it with BC's installed- they are terrible. Absolutely awful. The problem is that they are not at all suited to the application. The rear springs, which are mounted inboard in place of the stock airbags are sized without any understanding of the motion ratio and are about 1/2 the required spring rate... This resulted in an extremely bouncy, crashy ride in the rear. I would think that you could upgrade to a stiffer spring, but you'd probably need to re-valve the shocks as well which doesn't seem cost effective for what is a very cheap, entry level damper to begin with. I just bought a set of KW V3 for the e70, but not going that route on the e53
