I bought mine from Bob's BMW, but I can't tell you the part number of link to it because for some reason his whole online catalog of airheads parts is not functioning now. I tried to check against the progressivesuspension.com website, but there flashy, but mostly worthless/non-operable website also pukes out Java runtime errors...
Can't anyone test their website code anymore before going online with it?!?!? Argh!
I went with black shocks on my red LS - as I still run the flat black stock pipes and there is no chrome anywhere else on it, I thought that wen't with "the look" the best. But, if you've got chrome pipes on your LS, or it is silver, the shiny chrome shocks may really look good too!
