I'm really happy with my set up (see sig.) it's a little firmer than stock, but not by a assbeatin' lot

... although I bottom out every once in a while. The springs are about the lowest springs for G1. dropped 1.7" front and rear.
Cost $500
Installed myself in about 4 hours.
Below is a pic before the front settled out... when it was only about 1.4"... it settled over a couple weeks.
Another good way to go is with the Ground Control Coil Overs... then you can adjust your heigth when you want... not sure of $.
