There is a free app for the iPhone called angle pro, I used this to set my camber with the phone held against the brake disc.

For the toe setting I borrowed a laser tracking gauge from a local friendly tyre shop, the whole lot was done on the garage floor as everything is accessible so there is no need to put it on a ramp.

The only disassembly is to remove the mud guards.

A good alternative is to use 2 lengths of copper tube, fishing line and a ruler. Believe it or not this method is very accurate as I got within 0.5 of a degree before using the laser aligner.
