Hi My Audi S4 is currently on the standard 18" wheels, which I regreted not upgrade them to 19". Can anyone share their driving and riding experience on the 19" wheels. I am currently looking for a set of 19" 7 arm double spoke set, any recommendation of where I can get them from? Been looking at the Ebay, some wheels straight off the RS4 seem to have 8J rim width. I believe it is the 8.5J for the B8 S4. Does anyone know what is the offset dimension? Many thanks!
