I got a question for you.. what do you think are the best springs and how low do you go? If you have 18" wheels, you suggest a 1.5" drop or higher? Also, from what I understand, to lower a bimmer the RIGHT way, you gotta buy shocks, springs, and camber kit. Is that right? If so, can one of the tirerack guys give a quote (give a good one so lots of us online will buy from you) for this whole package? Thanks.
