IMHO.. the rear conversion is worth it to never, ever have to deal with the drum system again. I very much dislinke those... at least the parking brake is simple, like motorcycle drums.
Any truck or car drum system is a pain with all those springs, adjusters, and other bs. Ive had no issues, without using a proportioning valve mod, in my xj with zj discs. I have enjoyed the increase in performance, which I compare to the new rears I did on my wife's xj. Granted, it may also help that I went to braided lines, which will make for a bit less give in the hoses.
