don't mind Matt, he does that to everyone! The only new coilovers I can think of in that price range are Tein Basics. They should be height adjustable, but I'm not sure how low they go. You can get better used Teins for $800, but you have to find them.
With all of the low cars in your sig, I'm sure you know all about lowering = on bumpstops = mega camber.
