C4's benefit hugely from an alignment with seemingly wacky specs - it's really the factory specs that are wacky (seemingly lawyer induced). I've posted my thoughts before LMK if you want to pursue, or search my posts.
Lowering also helps, as does tire footprint, springs (start w/z51), and the quick steering rack. The z51 front control arm bushings are much better too but pretty hard to find - once you have and use grip the stock zr-1 lca bushings won't last long.
Don't know how I missed this post the first time around, I think I don't always make it into the General section!
Glad you had fun, I never imagined there would be something that could make me glad to get up early in the AM
