    Got my spc ucas on today and they got the caster to 1.9 and 1.8. I was not rubbing before and now I'm rubbing on both sides rear fender well. Should I change the setting or trim?

    I didn't ask I'm assuming he went by starting point on the instructions. Could I tell them to move the tire back forward some since the numbers are so low. Most guys up here are reporting 2-2.5

    Your caster was better before they "corrected" it.

    If they brought your caster out to 3° (where it should be)via the lower control arm adjustments you will have more clearance.

    I can't guarantee it, but that's my guess. I'd be curious to see where your rear lower control arm eccentrics are set.

    So I went back today and he maxed out the lower arm eccentrics and now I have no more rubbing. Brought my caster up to 2.4 and 2.5 He left my ball joints in the D position. Rides great!

    No you can reuse the current one if they are not corroded and you don't damage them removing the old UCAs.

    Thanks guys for the quick response, I will not be doing the install myself because i do not have room at my townhouse and the proper tools.
