I just put offset bushings in mine and can't hit 2* of caster :( was hoping for 4... not sure what the deal is.. MIGHT be too thick of UCA rod bushings pushing it back..
I had up to +7 on the left and offset bushings on both UCA's. I did adjustable strut rods and while I set them up to move freely I suspect I have one too long and the other too short. But I haven't had the time to check yet.
