going to be a looooong time before you see bilsteins at your door
if you're patient they are saying july/august... but then again at the begining of the year they said april... so who knows! Might be better off getting your money back and trying the Rancho Quick Lift Loaded. It's got adjustable dampening which is cool. A little more expensive though.
I'm in the same boat as you too, ordered bilsteins and got jerked around on when they're supposed to be coming. I'm probably going to go with the Ranchos, my wheels are at the border and my tires are supposed to be shipping today, I can't even imagine how anxious you are just looking at them in your garage!
Weigh your options dude!
