I am by no means an expert, or even all that experienced, but I will share my experience.
Car makes about 360rwhp, estimated, 5spd and 3360 lbs with me. I have ran a few different control arms, springs and tires, always a drag radial. Best 60ft was a 1.83.
I finally got tired and began to deal with Kevin Slaby from baseline, and ended up with his suggested rear setup. Here is what I have now:
UPR coilovers with 175lb springs
J&m weight jacker lowers
Stock v8 sprints
10 way strange all corners
MT 26X10.5 ET streets (8.5" contact patch)
Racestars big n Littles
I followed his plotting advice from his website and through several emails with him. 2 weekends ago I ran the car at Atlanta dragway in truestreet. I cut five 1.62-1.66 60fts, and a best of 1.58 60ft!
Alot of experienced racers told me to ditch the relocated stuff and that plotting a stock suspension car was pointless, but cutting .25 off my 60ft and grabbing my first 11 second pass was well worth the effort.

Working on the 60ft, thanks Kevin Slaby!
1.57 60ft and 7.45 @ 92.19, Previous best 60ft was 1.83.
