I have a question about this build... I am new to the jeep world and love mine very much. I want to do this build because of the extra stopping power that it would get and there is a killer deal that I came across for 99-02 oem still in the box calipers. I have read both threads only to find that both individuals used spacers and re-drilled wj rotors (which I am fine with doing). I think my main confusion is where or when they start talking about the spacers. Is there aftermarket spacers that you can buy? Is there a more proper fitting hub (in actuality what hub needs to be used) that a person can use or does that hub have to be milled? If this mod comes down to milling that's gonna have to be a bust for me unfortunately. Also does this mod require a minimum rim size. I think I read that somewhere I just cant remember where.
JKS makes the 1/4" weld-on hub spacer, it's been mentioned on this thread as well. About 15 bucks a piece or so. You can use stock XJ unit hubs on the WJ knuckles, no machining required. That's why you're buying the 1/4" hub spacer (aligns u-joints in relation to balljoints).
