I'd run a 7" front with 3.5 bs. The more back space the more grinding. The disc conversion will push your wheel towards the fender. At a 4" drop you probably would never have issues. But if you get greedy and go lower in the future you will have fender clearance issues with a 8" wide. To get a good night tire for a 8" rim you are looking at a 255/60/15 and they balloon out and are wide. On a 7" you can run a narrower 70 series. I'm telling you this from experience...I have 15x8 with 255/60 on front. I had to get PB narrow arms to clear my fenders.
