I'm waiting to hear from AJUSA on their current prices. The current price at 4wheelparts.com is $1,576 before tax.
I'm checking prices today/tomorrow and planning to put the full Bilstein setup on my '08.
The AJUSA website does show the price and that they're in stock. $1,360 for everything as a kit, including rear springs. $1,250 without rear springs.

Those are actually the same prices as when I ordered mine back in December. It was free shipping and no tax when I ordered (I assume no tax because it was an out-of-state order). It took a something like 2 - 3 weeks before everything arrived at my house. Each set of components within the kit shipped from different places.
