Hey everyone,
I've been doing some reading on upgrading my 2001 XJ's front brakes to the WJ calipers and rotors and found quite a few resources, a couple of which I'll share below:

Now, I've been mulling this over and the following seems to be true:

Now, I've been mulling this over and the following seems to be true:
- In early (pre-97) models, a brake booster upgrade is pretty much required. Everything I've seen has indicated the WJ dual-diaphragm booster is recommended, however, I already have a dual-diaphragm booster in my 01. I assume I can skip this?
- The article linked above (on 4x4wire) seems to go through a lot of seemingly unnecessary work modifying TJ hubs and bearings to work on the WJ knuckles. Interestingly enough, I found spacers from JKS to allow one to use the stock XJ bearings/hubs:

Will these spacers allow me to avoid dicking with aftermarket/non-XJ hubs? - I assume that no matter what, I'll need to buy a set of WJ rotors and have them re-drilled for the 5 x 4.5" pattern of the XJ. Is this correct?
- Buy WJ steering knuckles, calipers, rotors, and ball joints (and maybe tie rod/tracking bar?), as well as the aforementioned JKS spacers.
- Install the ball joints on my bare XJ front axle.
- Install the JKS spacers into my stock hub/bearing assemblies.
- Re-drill rotors to fit XJ hub bolt pattern.
- Assemble everything as needed.
- Upgrade to 16"+ wheels?
