preference for street/strip/cruise

just wanted some opinions i looking at at least mini tubbing my 80 olds cutlass and trying to decide between 4 link or ladders and coilovers or moving frame rails in 1 1/2 inches on each side and modify gm 4 trailing arm setup
main concerns are
money of course

traction issues

durability/stability

ease of adjustment

i have plenty of room to do this and also have considered full tubs
and have (i believe...)all the tools lifts,hunter aligner,frame machine mig, tig, heli-arc
i do auto for a living but trick suspension stuff i dont have a whole lot of experience in all opinions appreciated thanks alot in advance fellas, and dont forget the ladies thx also

A 4 bar with coilovers and a good panhard bar is probably going to be the best setup under the car. The triangulated 4 bars are nice and eliminate the need for a panhard bar.
