55.2-59 C4 IRS on a 55-59?

Ive been going back and forth on suspension lately and have been leaning toward doing C4 suspension with Flat out kits. The front seems pretty straight forward an looks to give a similar ride height to what I have now. When it comes to the rear I had bought a 8.5" 10 bolt posi and was going to do a 4 bar to give myself ride height adjustment. Recently I started looking at the C4 IRS and there seems to be some pro's and con's. Don said his kit gives a 1" rake front to back which would increase if you do staggered rims. I was thinking 18's and 20's but could do 18's all around. I would like to keep my truck fairly level. I've seen some that have a great stance and some that are higher in the rear than I like. I spoke to a local vette yard and they told me $500 for a front and $1000 for a dana44 rear. I'm going to be shortening my frame soon and figured I would do the rear suspension at the same time.

for those that have done IRS on a Task Force I have a few questions:

1. would you go with the newer wider rear or the older narrower setup. Im planning on a little over 400hp stick shift so it will be a Dana44 regardless.
2. How does the ride compare a 4bar. I like to hit the corners but probably going more pro-touring than auto-x
3. did you do anything to adjust ride height? Shorter coil overs, or shifting mount brackets etc?
4. Any difficulty with rim offset?
5. Would you do it again? I'm sure I could easily sell the rear end I have in the shop. For me the c4 solves the rear disc and parking brake issue from the get go but the IRS adds more moving parts.

Anyway I would like to hear what you think or susgestions you may have.
