Get the C Springs, a set of weld in subframe connectors, and a set of southside machine lift bars and you're good to go.

I have the C's on my car and I'm very happy with them... Paid $150 for 'em at summit. One word of warning though... One of mine was defective and the car sat high at one corner. Just eye ball 'em up when you get them out of the set and make sure each front and each rear match their mate.

Also... I'm pretty sure they are progressive in the rear since Ford lists 2 numbers for their weight rating. Progressive springs progressively change rating when more weight (or force) is added to the car. I also seem to recall the rears being wound tighter at the top, which would support my theory.
