For Sale is a complete Bilstein PSS10 Coil Over setup. According to specs this will fit all e82's and e9x. Had these on for about 29,000 miles and loved them. On softest setting these are just as comfortable as the stock suspension, if not more so. For specs see the link below from turner motorsports which is where I bought them from.
About $2000 new, I will take $1200 shipped OBO.
For pics of my car with these on:
