I need new wheels for my 2001 A6 2.7T with the large HP2 callipers. I don't think most of these wheel shops are aware of the large front callipers and the need for the clearance. are there other specs besides the offset(which doesn't seem to matter) to find wheels that will clear the brakes. are there certain brands or manufactureres that make wheels for this car. I know they're out there cause I have after market wheels on there now but nobody stocks wheels for this car and getting them on line is not looking very successful either. any help would be great. thanks

 

While this doesn't answer your question directly, these wheels may work for you, if you wish to go up to 19" wheels.

Ebay has a few that sell wheels to fit A6s with large front calipers. I even found clones of my stock ones in chrome. I dont know how you feel about ebay (everyone is different) but they have some stuff. Just check with em and if possible get a email verifying they will fit your model. Some, as with most wheel retailers have that $250 restock. I've been meanng to get wheels but whenever Im ready.... something else breaks or leaks. Good Luck.
