My Zuk has a basic spring over and I'm considering moving the rear axle back 1" with the Spidertrax relocation plates. Will there be any problems with this? The only thing I can come up with is the passenger side tire might rub the metal cover for the gas filler hose.
If your running just 32" then you shouldn't have much of a problem. Have you considered just redrilling your spring perches and ubolt plates. The whole project will probably only take a couple hours, and better yet it's absolutly free and accomplishes the exact same thing. Just my .02
It would depend if he is using lift springs. If he has the stock overload spring he should be ok. One thing I wacth out for is possible contact between the gas tank skid plate and the diff. But only an inch, probably be ok
