bigdog - If they are coil overs you would screw the two nuts clockwise/up therefore moving the base of the spring higher. This does not compress the spring rather it just moves what it's loading to a higher point. You want to try to determine how much higher the chassis need to go and then screw the nuts that high and check. They make a funny wrench for these nuts - mine came with the car and makes the process alot easier. This adjustment can be done on the car but is much easier if you remove the entire coil over assembly, adjust each one and remount. Best wishes!
