Another option would be to order some Bilstein HD's from Germany (see this thread) -
F/S direct from Germany-Full Set of Bilstein HD Brand new, never mounted
then have them revalved by Bilstein in California or a private shop such as Fat Cat Motorsports. You will need to know what spring rates you'll be using before they can do the revalve. Revalving runs about 75 to 100.00 per shock. In the long run they are still a LOT cheaper than Hotbits, DMS, etc.
