I have been on a quest to find myself a good used set of 19' alloy wheels for my Audi A4 B7 S-Line Saloon, to find myself stuck when they start talking ET's and Offsets. I did some reading and know they basics, the lower the offset the more it 'sticks out' toward the arch and the higher the offset, the more it 'sticks in' to the arches - but I don't really know the range in which I have to play for my A4 without causing any rubbing or fouling of the calipers. I've tried searching but to no avail..
Can anyone help?!
I am looking at some Audi/BBS Speedlines in 19X8.5J - PCD 5x112 - ET48 - Center Bore 57.1, and the supplied tyres which will need replacing are 255/35/19.
