Doing the math

[raisinracer]

I'm in the planning stage for the next up grade to the truck,it'll be back halfing and caging. I've already got a pair of 18.5/31/15 hoosier quick time pros and 15x15 convo pros. This weekend I pick up a 9 inch housing. I'm still up in the air over 4 link vs ladder bar, though I'm leaning to ladders. I downloaded a work sheet from ca chassis works and filled it out. I thought that I'd put it up for checking and out for sugjestions.
