Reason i ask is i have 2 good 8" rears i want to put on the front and am looking to buy 2 9" rears for the back. Will the non-shp 8's fit on the front or is the offset going to hurt me? Anyone know?

Got a friend with mega squirt on a 4g63. He needs a base tune to get it running. I have no experience with mega squirt at all. Any help would be appreciated.
