They are on my A4 at the moment, and I would need to find some wheels to replace them with too!
I'm after some Audi A8 Fat 5's and have found a couple of pairs, but just got to secure the deal with them first.
So, they are 5x112 and 8x18" with an ET of 48. I run 10mm spacers on the rear of the A4 with no rubbing from front or rear with a VERY low ride height.
I will post some proper photos up tonight/tomorrow of each wheel.
Any interested parties at £650 firm, please PM me.
