I'm doing some rebuilds on all my cars, and by that I need to set up the wheel hubs correct again. I Know how to do it, I just wonder if there are any DIY guides for making some tools to measure
and get the correct toe in, camber and so on? I remember seeing someone making some discs to put on the wheel hubs and some tool to measure the degrees.

Any got som information to how this work, how I can make them and how I use them?

naaaaaah,

get one side looking how you like it, then take the other set of links and match them up to the adjusted ones. then eyeball the end result.

so at the most all you need is a ruler and calipers.
