bmw roof rack configuration
have a question about roof rack configuration. just got a 2nd hand bmw roof box 450 and would want to save some $ by trying to optimize the configuration of the roof rack and box myself. cant seem to find anything on the internet though as to the optimum way to do it. so far, all i know is that it looks nice right in the center of the vehicle, and that it should be forward enough to allow the trunk to open. anything else i should know/do? anybody have pictures?
