Yeah people try to do that to clear bigger tires without tubbing. It's just the lazy way to ineffectively make room for bigger tires. I have mine at the B or C setting I think. I wanted more caster out of it.
You made the right decision IMO. I tell my friends that heims are for race cars, not daily driver off road trucks. I did just buy all the parts for heim steering, so don't listen to me too much. Mine is far from a daily driver now though.
Yeah mine's a daily driver and hopefully this will be the last stuff for a while (i keep saying this shit). Guess i'll set it on D and the plates with positive caster and see what shakes out. I think when I burn out the 33s I'll jump up in tire size but that'll require a re-gear so I might as well lock the front.
Probably nothing wrong with heim joints but just a bit less maintenance friendly.
