They are MTM bimoto 19 x 8.5 Et 35 they are a perfect fit to the A4 no messing with spacers (done that and got loads of Tshirts)
They are heavy by comparison to OEM wheels so not good on the unsprung weight front, but I personally think this wheel is a great compliment to the B7 shape and not dissimilar to B5 RS4 wheel which is one of my all time favorites,
I am a fan of MTM not cheap though but they seem to get it right, Germans again! check out their performance upgrades really spectacular results.
