[SCOTI]

The adjustable panhard bar will get the rear centered after it's lowered but you might still consider an adjustable sway-bar to help combat the natural twisting motion the driveline follows.

Most of the time when you see one of these trailing arm trucks actually hook up, you'll notice it's the pass front wheel only coming off the ground because of the driveline twisting. Ideally you want to prevent this unwanted motion & transfer it to the ground, equally w/both rear wheels.

If you've ever gone to one of the fastest street car shootouts you'll see alot of cars dragging the rear bumpers pulling wheelies . . .... but usually only on Fri night. By Sat, they're dialing in the suspension to work best w/the track (adj pinion angles, sway bars, pre-loads). Wheelies look cool but slow your times down. I'm not saying you must run out & get a sway bar or you won't run fast, but it's another thing to consider when tuning. Same w/shocks, the Qa1 adjustables are cool if you can afford them, but sometimes cheap old regular NON GAS front shocks & standard replacement gas rear shocks can work just as well.

It looks like you've got a solid plan started. Keep us posted on your track times, get a good baseline & remember to only change 1 thing @ a time so you can track the effectiveness of that change.
