Haha.
I'm glad I had that little camber tool (I'll check tonight but the Gunson tool I bought may fit inside the centre wheel cap once it's removed). I had to make the fine adjustments in a very small, quiet trading estate, completely flat surface. My parents drive really affected how off I kept setting it
To make the adjustments, ensure you're on a flat surface, take a quick camber measurement, in my case a spirit level across the wheel rim, then using the camber tool in the middle to get an approximate reading.
Then just jack up the front on the side you're working on, (you can check the camber again just to see how it is when the wheel is hanging in the air), I jacked it up so I could get to the nuts easier (19mm & 30mm).
Undo the 2 locking nuts, and adjust the adjusting nut, lower it back down completely - and measure the camber again. (repeat as required )
When happy, tighten the 2 locking nuts.
Feeling pretty good, both are set to around -1.5 however it just needs to be aligned properly again by someone.
