What kind of front tires do you have, can you test drive it a mile or so? I'd test it at a height that you might want, then check it on level ground. Play with the height until you can settle for it there, then get an alignment. Have you already installed camber washers, you will need them to gain proper camber specs?
If you need a lower height, you can get lowering keys, I bought a pair recently for $90 from Total Performance. I have one stock key flipped, and with rebuilding my suspension, I want to have two keys in it seated correctly. Regards,
