Just had tracking done ...

FRONT
Left Toe +0.10'
Right Toe +0.10'
Total Toe +0.20'

Left camber -0.04'
Right camber -0.35'

Setback -0.03'

REAR
Left toe +0.17'
Right toe +0.19'
Total toe +0.36'

Left Camber -0.34'
Right Camber -1.36'

Setback +0.10'


1.What is setback?
2.Why would the rear left and right camber be out so much?

Additional Data
Left lateral offset -0.03'
Right lateral offset -0.05'
Axle offset -0.01'
Wheelbase difference -0.04'
Trackwidth difference -0.08'
Setback Front Axle +0.05'
Setback Rear Axle +0.10'

3. I don't understand much more than 'toe'... anything i should be concerned about in additional data?

Should i be concerned? is 0.01' much in realterms?
I never had this setback thing show up before. A new subframe went in with the new engine could that cause setback?

setback on the rear beam could be because it is not straight?
