Replace those wooden shims with sheet metal plates with some grease between them and you can make your toe and camber adjustments without ever moving the car.

Also, I tried the string method, but it became too cumbersome. I bought one of those laser line levels and press it up against the hub without the cap, with the laser pointing at the ground. It makes a line alongside the tire long enough to mark a point in fron of and behind the tire to make the toe measurements.

For camber, I use a SmartTool digital level that I also press flush to the hub without the cap. It reads the camber directly. These two tools now make it a snap for me to check toe/camber quickly and easily anywhere I have a flat surface (the digital level on a long straight edge works to confirm a flat area.).
