I saw the GD3 self repair but this question is a bit more broad. I have GD3 and actually do not care what or if the front sway bars are a bit on loose side, this comes a bit from back round with autocross and off road stuff, i distrust sway bars on drive axles in open differencial cars, so if its a bit worn i don't care unless i can be convinced otherwise.
However if it is to be presumed both end links, and specifically rear bar likely could be worn out (original factory 15 years, 120k miles) then my question is
A. Are there any worthwhile adjustable end link kits for rear bar that work on stock bar?
B. In regards to autocross scene, how common or worthwhile is worrying about rear swaybar (in more stock oriented classes)...Balance of car makes me presume its very worthwhile but i'd love others input.
C. is there any cheap upgrade for rear bar, i doubt this but in some cases another vehicle of same make features a swappable part that is much cheaper then fancy aftermarket stuff. (can be junkyard sourced etc)

Thanks for your time, if i am hugely off the mark feel no need to insult me I'm all ears, hopefully can come to better understanding if that is case but i hate sway bars on drive axles like you wouldn't believe, just not enough to remove stock ones.
