What 15" aluminum wheels are you guys running over the 11.75" rotors?

I just went and picked up a single 15 x 7 jeep alloy rim (on the cheap). I set it on top of a spare front rotor with a 1.5" wood block spacer. It clears the grease cap ever so slightly. Might need to sand a couple 32nds off the center cap barbs. I still have to mock it up to the car.
