deep dish often equals a lower offset.
so it's kind of a trade off. you could get wheels exactly like on the porsche, but they'd stick out like an inch or two from your fender.
you just gotta find a balance of all three that works for you. (offset, "deepdishness", how for it sticks out)
mikes95rt has nice lookin wheels imo. they are exel or excel mimi's i believe. they are only 7.5 wide though i believe, so you might have a hard time finding them wider but i'd at least try. they have some decent "deepdishness" happening. (yes! another made up word! i'm at five for the day!
