Stop in for a cup of coffee
Is there any rules of thumb when it comes to adjusting the caster bolts on the UCA?
Couple of coffee club tips.
Moving either bolt changes caster about twice as much as camber.
Depending on front and rear suspension mods, there is some degree of challenge in getting a lot of positive caster.
There's at least couple different approaches. The Master Tech goes over at least one time saver approach.
Starting from scratch, I'd start with both bolts at mid-point. Drop the car and see what the camber and caster is.
To change just camber, move both bolts the same distance (rotation).
Drop the car and remeasure.
With the camber close to what the tires want, then go onto caster.
To get more positive caster, move just the rear bolt inward
if there is room to do that.
That will increase negative camber somewhat, and increase positive caster more.
