edelbrock adj panhard bar
 

i know the bar is adjustable, but it does not say you can adjust on the car, probably a dumb question ? putting the roush rear springs only to level car,front spoiler drags on about any driveway so no front lowering. have 285/40/18 on the rear.

Read their instructions. It states "turn the adjuster sleeve until the rear-end is centered". Can only do that ON the car.

It's on car and probably the easiest one to adjust.
