I am looking to find someone to swap my 2011 S4 wheels, for their A5 y-spoke wheels. Does anyone know, can these wheels be interchanged. they are both 19" x 8.5, but i am not sure if the offsets are the same. Any info would be great. and If anyone knows anyone that wants to trade wheels drop me a line. My wheels have about 12,000 km on them (8000 miles)

thanks
