This video covers most of it thoroughly. When I did mine I did not do anything with steering mods. I just needed the braking!

You can fit "some" 15" steel wheels, but not all of them, and if you have aluminum wheels they have to be 16" or larger.
Use something like this (http://www.rottenleonard.com/Drill-guide-price.html) to re-drill WJ brake rotors to 5x4.5
The WJ steering knuckle mounts the tie rod 3/4" lower than stock.
The 93-98 (ZJ) Grand Cherokee pitman arm also moves the steering 3/4" lower, so you can use it to compensate if you don't want to change your whole steering setup.
I had an XJ with ZJ rear discs and WJ fronts... I have never had a car that stopped so well, before or since. I miss it!

Thanks for reply. I've asked for wheel diameter because in italy isn't legal change the wheel diameter (stupid law).
I can only use 31-10.50 x 15 or 33-12.50 x 15....

I was able to put 15" Method Bead Locks on my conversion,I had to sand the calipers a little but that's it.

Running 15x8, 3.75 BS steel wheels clear my WJ setup.

Here is pretty much everything I used (far left column).

I suppose that will be more easier do just brakes upgrade...
