Upper or lower control arm adj for Caster
Just got 37s. Firmly believe in increasing the caster angle from stock 3-4degs to 7 as has been done successfully by many. Read the excellent WOL write up on subject.
My question is: should I adjust the lower CA or the upper CA to achieve the result? Are there pros/ cons to either approach?

Probably the uppers, but depends on where they are set now. Uppers and lowers to the same thing, just backwards of each other, so adjust whichever gets the axle centered in the wheel well and the caster/pinion where you want them.

I've since read that can be the downside of just doing the uppers (not enough adjustment).
It still made a HUGE improvement in my flightiness. But I just bit the bullet and ordered some adjustable lowers today because I want it to be right.
So much for saving money.
If I had to do it again, I would start with the lowers and see how that helps. The lowers are easier to install too, although the uppers weren't bad.
