Wanting a 18x9f 18x10r wheel setup am I crazy?

17x8 with 5.72 bs won't work in the back without spacers or a B body rear end, how is an 18x10 with 6.57 backspace gonna work?
me thinks the clearance on the front is the least of your worries, in fact the fronts will likely fit just fine, just rub on full lock.
