Yes i believe the diff front discs push the mounting surface out a bit, from what ive read i think its 3/8". I never measured before and after. I dont have to run a high ride, i havent measured my fender to ground clearance but it looks in line with what im seeing other people run with similar size tires. What i did to.check the clerance everywhere was i got an unmounted mustang tire with the backspace i was looking off of ebay cheap and mounted it all around and measured from there taking in to account the tire size. Maybe theres a cheap wheel on Craigslist near you or in a junkyard.
