So i went on the bistein website to get the part numbers for the shocks for the f30, and link to that is

then i googled the part number listed on the bilstein site, and found a company shipping to the US who has it, here's the link. It says it is for the "canadian" f30s, but im sure that it will work for the the US as well

so seems like you can get the shocks front/ rear for $880 shipped, plus about $200 for the springs, and for $1080 get an awesome spring / shock combination. I think i will pull the trigger on the b8 shocks w/ h&r springs in near future.
