camber adjustment
I lowered my rear suspension with longer boltsand now I have too much negative camber. the adjustment cams are maxed out. is there any other way to get more adjustment other than installing adjustable lower strut rods?

You could also get lots of adjustment using heim joint adjustable strut rods.

with the heim joints, but im sure you have a saggy spring. i lowered mine with no camber problems and plenty of adjustment left

fiberglass is stock on my 81, if you ever have a fiberglass spring break in half on you while driving you will never want another one. people talk of the side differetial yokes wearing, I have not had a corvette apart but if it is set up like a standard rear axle yoke there is nothing to wear except where the seal rides on the yoke, what wears on these yokes?

The ends of the yokes wear inside the diff. That's why they make yokes with hardened ends like: 1963-79 Remanufactured Heavy Duty Differential Side Yoke
They describe the problem as: "The stock side yoke ends wear down depositing damaging metal into the rear end. Worn yokes cause rear wheel camber problems which causes tire wear. Our retrofitted side yokes are made from original GM yokes. Once reconditioned, precision machined 0-1 tool steel button inserts are installed in the ends. The button insert itself is hardened and press fit into the yoke."
Also, strut rod bushings that are "bound up" and don't pivot as the trailing arm moves causes undue pressure on the yoke, causing this wear. So you might have to do exactly what I did...start from scratch on the rear end, replacing/repairing everything.
