People want to believe that the M sport packages are cosmetic only but I just don't think that's true (with some exceptions). My 740i sport had M sport suspension and it was literally a different car than a 740i. The 550i sport was transformed when it went from BMW sport package to M sport package with the LCI update in 2007 (which is only this year being advertised as an M sport suspension).

M sport, as the letter implies, is specified by GHMB Motorsport division. The springs, shocks, bushings, bump stops etc... They are a seperate company with their own test track. From a performance point of view is goes BMW then BMW sport pack, then M sport pack then M car. Again there are exceptions, but I'm surprised how many people think M sport is just for show. If that was the case I'd have bought an M sport X5 for my wife. I didn't because I don't want the baby riding around on stiffer shocks and springs etc...????
