All the fixed designs are all the same in terms of extra caster. The QA1 is the nicest of that type.
However, with the other options, those arms are obsolete.
OK so how does the PST ones compare to the QA1 and how much do you want for the QA1's with the small ball joint?
and yes I know my first question was about the big ball joints
I was planning on going with the PST LCA rebuild kit.
