Any way to get more caster adjustment without newer adjustable CA?

The caster is also somewhat dependent on the ride-height as; the strutrod moves the LCA around some, and; the UCA moves the upper BJ back and forth.
The trick in the alignment, is to let all that happen without letting the camber stray too far, and jacking the toe-in around.
3 to 3.5 positive is nice at the bigend, and also at cruising speed for hours on end. It is definitely worth the getting. For me zero sucked!

FWIW; the offsets got my car over 3.5* caster at zero camber.And I yanked the LCA ahead for another .5*. I gave up a little to get some negative camber. My 245s wore flat across at .5/.8 neg camber, with 30/32psi. And those stickies cornered pretty good.
