I got mine isntalled at whiteline because I don't have access to an alignment machine!

If you are only going for the rear bar, then you could probably do it yourself. But if you want the caster kit and the full alignment too (which I definitely recommend) then you should goto whiteline. Woijtek (sp?) knows his stuff and you won't make full use of the kit unless you get a full alignment.

Their alignment machine is top class too.
