Traded my 98 540i sport for 99 740i and in my 4 days of ownership, i really can't believe the difference in build quality. The 5 was sporty, but didn't really feel like a world class auto. The suspension i thought was a bit firm for a daily driver, and the setup on the 7 is a bit soft. Found Bilstien rear shocks HD for $132ea. and wondered how much firmer than stock these would be. I know the OEM sport pkge. shocks are 100% firmer. Can i use either w/ stock springs? Don't really want to change the profile w/ lower springs. Can't seem to find front Bilstein except from Dinan. Way overpriced and don't know if these go with stock springs? Is replacing "shocks only" a waste of time/money? Same labor either way?? Thanks for any insight here. Regards, Alan 99 740i
