I can add a little further info regarding 16's for the speed. I sold my 05 Tribute wheels to a 1g speed3 owner and we test fit them in my driveway to make sure they'd fit. They are 16x7 with a +45 offset and just cleared the front caliper.
So a +45 will fit but I am sure you would want to take into consideration the spokes on different wheels as some may rub the caliper.
