question 1: would they clear my calipers?
question 2: would they fit my OEM tires 225/45/19 -fronts; 245/40/19-rears???

please help and thank you

of course the guys online (aspecwheels in oakland,USA) told me they will fit but guys here in canada keep telling me the offset in the rears are too low? what does that even mean????
