I'm learning how to do my own alignment (MFE's posts have been bookmarked for years and it's time I get on with it; the 95 spindle install I did last month necessitates this!!!). While his instructions focus on the front wheels, there are other writeups that are for cars with adjustable rear suspensions where the rear is aligned first. Should I care? I'm lazy and it's an additional step lol. I know I can't change the rear's thrust angle (easily with the current suspension setup at least), but I could use the thrust angle as the proper front toe centerline. Anyways, thoughts would be appreciated. I've driven this car 200 miles in the past year.
Suspension Setting Front Alignment - Do I care about the rear's thrust angle?

Only way I know is to have a full floating rear end and use shims on the end of it. This is only done on race cars not street driven cars. Buddy of mine had -1 deg in the 8.8 on his American Iron car. I believe Bruce Griggs set the rear end up or advised him on how to do it. Again, this is a complete waste of time on a street car unless you have an IRS in the car.
If the thrust angle is off(rear axle not squared-ish- to body) something is wrong... Worn bushings, something bent, misadjusted control arms(if not stock arms).
If it's off enough the car will dog track down the road..
If you're talking less than say 2 degrees, don't worry about it. These cars bend and flex a lot nothing is ever perfect
