You can do it in the rear with just a 1/2" offset. But you'll have to do a "reverse mini tub" like I did. If you remove the section of the outer wheel house that angles down to the quarter and replace it with either a piece that goes straight across to the quarter, or a new outer house that has a 90° corner and goes straight down to the quarter lip you'll have the space. Take a look at my reverse mini tub in my build thread. Pretty sure I could fit at least 315's on my car with the measurements I have now.
