what would be a good number when you are back steering.took spring and shock out and run it though its travel and lost most of the camber set in the car. can adjust the upper. we are set at 4 and gain up to 6.5 strait but turned to right we are 1.6 strait and down to .09 turned to right. any ideas would help.

Stop and think about the angle of the balljoints when turned? If you turn 90 degree's the camber of the tire is the caster + inclination of the spindle at that point. This just shows it will lose camber depending on how far the tire is turned.

Example RF tire: 5 degree's camber, 5 degree's caster, and a 10 degree spindle. You have 5 degrees camber when the tire is straight and if turned 90 degree's right (I know you can't turn it that far but imagine) Your tire will lean out at the top what ever your caster was set too plus the inclination of the spindle for a total of 15 degree of positive camber.

How close it goes to those numbers is dependent on how far you turn the wheel.

PS, I left out anti dive/caster gain just for simplicity as it will effect this also.
