off set upper control arm bushings worth it???

Most alignment machine have the specs loaded in their software.
Those may be factory specs or may be updated specs that take radial tires into consideration. Bottom line If as much as 3 degrees positive caster is recommended or called for, you cant get it from the OEM parts.

i don't know about that. i know for a fact djvcuda got 4* caster out of his front end after rebuilding it without offset bushings. he used a poly kit from just suspension i believe. depends totally on the car .

most machines have the stock settings loaded in them. unless you have an alignment guy that ignores those settings and really knows what he is doing it just won't be right.
