Move the axle back into the stock location.
Reason is if you ever want to run some bigger tires they have the possibility of rubbing at the back of the wheel well.
I have 325/50/15's on mine. Some guys were trying to tell me to center the tire in the wheel well. I am glad I did not listen to them cause the tire would have never fit. I would have had to cut all my link bars back down and put it where it is now. Just an FYI
