Oohh the meister would look so good. Basically offset is where the hub face sits in relationship to the center of the wheel. Kinda. Lol. So technically the lower you go, the more dish you get. As long as it clears your calipers, I would run as low an offset as possible to get more dish. Balance it between flush with the fender though, because offset will change where it sits in relationship to the fender as well. This make sense? You're doing staggered offsets right?
Edit: to be safe, the +35 will push it out and give you more clearance from the strut. You can modify the fender, not the strut. unless you ran a spacer, which you probably shouldn't do.
