On my 79 Zephyr wagon with a small block and A/C, I would like to have a lowered stance along with excellent handling. I am installing an AJE front K-member, Mustang GT rack and spindles.

So, here are my questions:

1) Which front and rear coil springs will give me a lowered (2" all around) stance?
2) If I decide to go with coil-overs what front spring rate do you recommend?
3) What brand/source is a good
low cost
coil over?
4) With a lowered stance what type of rack bushing do I need, off-set or standard?
