If you read Carrol Smith or Fred Puhn's books, you will see there are multiple ways to do this, but they all involve moving a suspension through its' travel range, and measuring the change in toe. The change in toe is what is important, and not the absolute toe value, so home made devices work fine for this.

I use a home built laser device projecting onto my garage door like this:




The bump steer curves on my 986S were pretty bad with significant toe-out in bump, and toe-in in droop. It takes a bit of shim work to get a good curve.
