WJ brake conversion is for the front, KJ and ZJ are for the rear and are essentially the same thing. You will get far more performance out of the WJ front conversion than you will out of a rear disc conversion. It also has the benefit of cross over steering.
What is your projected cost for that set-up? Does that cost include replacing the stock steering?
I'll disagree with that statement.
KJ swap was the best move I made, until now.
Can't wait to get the fronts installed and I'm ordering the rears this week. I passed on the WJ.........just not where I wanted to go, ultimately.

Have you looked at an online factory parts retailer for the plate studs?The simple fact that I wouldn't have to adjust drum brakes anymore is plenty enough reason to switch to KJ brakes on the rear. that and easier maintenance. only trouble im having with the KJ swap is finding the backing plate studs, as the ones that came off the donor were too rusted and new ones from the dealer are $12 each.

Fresh drum brakes adjusted correctly are pretty much the same as kj/ zj rear disk brakes IMO. Most people praise fresh rear disk brakes as superior to wore out drums.
Having done both front WJ and rear ZJ. Fronts will be noticeable improvement in braking..
I love how no one has answered your question.I've finished my 4.5 lift and running 33's. I want to improve the braking performance. I've seen WJ and ZJ disc brake conversions. What are the differences? And what if I want to do to a WJ in the front next?
Assuming your asking what the change is as compared to stock. I cant speak, I haven't done the WJ swap. Just amused at the ensuing arguments over drums, disc and what not. I too am curious as to what kind of change could be expected from a WJ front swap.What are the differences?
I love how no one has answered your question.
.
Less fade, better heat dissipation, superior wet weather performance, self cleaning, ease of maintenance and adjusting, better bias from front to rear and side to side all make rear discs far superior to drum any day of the week.
Sure fresh drum bakes might be equal to discs in your opinion but what about when the drums start to wear, or get wet, muddy, hot, or out of adjustment? Which all will happen.
You cant honestly say that the performance for the life of the discs are going to fluctuate and change as much as the drum set up.
IMO rear discs should always be swapped before doing a WJ swap.
The very first response answered the questions.
Have you done both?

No it did not.
WJ brakes are the byproduct of steering and TB geometry........that is the job at hand.
I would love to have crossover steering, but not at the expense of braking and not at the expense of TB geometry.
Can I fabricate? sure. Can I cobble something up for braking? possibly.
I've been through EVERY freak'n WJ thread, read every word, learned from every mistake others have made..........seen every F'n hack job too.
To get the TB right takes a lot of work and some sacrifice of other parts and arrangements such as sway bar mounts........just not worth if for me. Others done the full WJ axle swap to get there.............
If you think WJ brakes are a bolt-on wonderment............dream on.
