Rear toe in woes

[Wynand]

Just a note of caution; when using a spirit level, make sure it is true - there is a simple test; draw a level line on wall, turn level around (left to right) and see if it still on the line drawn. Same with vertical check.
Recently I had to check 6 levels at the hardware store before finding one that was accurate.
When measuring cambers, etc I prefer to use a master "Promac" level that's adjustable.
