IMHO, if you are after the mean look then you should probably go with a mild lift at least.

I'm running 33x12.50's on 15" rims but that requires a lot of offset on the rims to clear everything. There are plenty of pix in my gallery to see what I'm talking about. I'm running a AT now but had MT before.

The rear coil replacement and the torsion bar crank are very easy. Any Mom & Pop alignment shop could do it (or even work it out with the kid working in the shop to come to your house & do it in your driveway, then drive it to the shop for the alignment). I assume that the box store shops won't because of liability reasons.

Sorry but I don't have any experience with the tires you're looking at.
