Rear Toe alignment shims
Does anyone know if there is a relationship between degrees of camber change and the thickness of the adjusting shims on the Rear assuming you are using fixed adjusting shims not the moving camlock. For example if I move the hole in the shim 1mm that equates to 1/2 degree change at the wheel face kind of thing.

I use Smart strings and a laser level with a ruler on the front hubs to check thrust angle.
Pm me your email if you would like apictures of the thrust angle ruler setup.

It's WHERE the hole is drilled in the shim that changes camber.
A kit usually has 4 or 5 shims with different holes drilled at different places to allow you to set the replacement bolt in or out more to move the wheel & change the camber.
Each kit could vary, mine IIRC is about .2 degree of camber more or less for each hole change. I never bothered to measure how much the hole moves from shim to shim.
I would think a good machinest with good equipment could make a kit in an hour or so. Mass produced , of course, much quicker.

Pfadt camber kits - the notches and the shims are both about .2 degrees.
Ernie,
Would like to see your smart string method. I've noticed toe change without adjusting camber after a few hpde's, thus it would be good to be able to check it without a trip to the alignment shop.
