The more you lift the less caster you can get into the OEM system.
Less caster means more road way input...ruts/cross winds.
More caster it tracks straighter with less driver input.
Is there such thing as too much caster? I was able to get 4.7 and 4.9 caster with JBA High Caster UCA and stock LCA. My alignment paper says "Specified Range" is 2.5-4.0. I'm running bilstein 6112s at max height so that's roughly 2.5" lift?

It's taking sometime getting used to my new caster settings. I have to give more effort to correct any cross wind or wide curves on the highway.

I'm probably going to need new LCA someday. I'm on my stock ones at 250k. The alignment tech said the bushings are stiff and starting to crack but there is no unwanted movement yet in the LCA.
