When Lowering the rear only, Alignment nessc.
If I lower just the rear on an 84 z51, do I need to get an alignment?
Second, do I have to remove the rear wheels, I have heard both ways, I really dont want to remove the wheels.

Lowering should increase negative camber a bit at the rear, and will most likely increase the toe in.
Check the toe with a stick or something that you can run under the car, and turn in the tie rods evenly as required.

ez way to check toe
cut two pieces of 1 x 8 ( really 3/4 x 7-1/2) board same lenght as tire diameter...lay the boards long side on ground , leaning squarely against tire at about 45*...now you can easily measure both ends, as long as you are reasonably gentle the boards won't move

If you're only lowering an inch or so, probably nothing to worry about. You'll gain a tad of negative camber but that's a good thing on these cars. Chalk line your tires and get an accurate before and after measurement of toe, but that's not likely to change enough to matter either. Still, I'd be more concerned with any possible changes there than with the camber.

"I have heard Z51 cars sit higher?"
Other way round.My factory stock Z51 is so low at the front can hardly get fingers between guard and wheel whereas most stock Vettes have a couple of inches.

I'd love to do my own alignment as I autox and am alway tweaking stuff & like to try different aligns.
Do you have a link to a do it yourself align. place?
TIA
