If you did swap to the standard offset arms it would only pull your wheels back 3/4 of an inch, as that is the difference between the standard and forward offset arms. I think you have other problems, with the k member and the forward offset arms you should only be 1 and 1/2 inches farther forward than stock. Hope you figure out the prob, good luck.

Jack should be able to give some hints on to which arms you have. Your pics looks similar to pics I've seen on cc or corral with kmembers and offset arms. They were also running different size tires. I'll see if I can find that thread.
