Is this correct guys?

Essentially yes. UCAs have some caster built in already making it easier to get to a good performance alignment. A good aftermarket LCA will reduce if not eliminate tire rub caused by running lots of caster (which moves the wheel to the rear of the wheelwell) by moving the lower balljoint forward in the wheelwell. Other than that, after-market arms are pretty.
