[s-cars] UrS6 Wheel Question

[iain.atkinson at tesco.net]

Following on from my recent winter tyre question i have been on the look for another set of wheels. The wheels on my car now are 8j x 17 ET40 and are of a 10 spoke design.

The following i can get a hold of

7j x 16 Et37 which are a 5 spoke design

7.5j x 16 ET37 which are the Avus style of wheel found on the urs6/S2.

Any ideas which one of these will best for winter tyre fitment and will using n ET37 wheel foul the HP2 type front calipers??? I am thinking that they won't as the Urs6 avus style is Et37.

NB all wheels i have seen are genuine audi

TIA folks
