On my Wagon, as far as the suspension went, in the front I replaced all the bushings with poly, used the stock swaybar, Monroe Gas shocks, and got a set of 1" lowered spindles. In the back, 8" rear, high durometer rubber front eyelet bushings, aluminum spacer blocks, re-arched leafs, none removed, front segments clamped, load handling gas shocks (all I could find for it) with the springs removed, and a homemade set of slapper bars. 60' time: 1.32, no nitrous with a C4 and 4:10 gears.
