Doubt you will find anyone running test lab testing all Audi wheels
to destruction just so that very few of us will know how they performed
Don't know about "stress risers" either...
On a daily driver you could put motorcycle wheels(doubt you will)
where it counts is driving on dirt, offroad etc.
have been driving on dirt, washboards etc last 5 years using Audi 5000T
alloys
with centers opened to 2.5" dia hole
suspension bottomed out many times.Wheels? Indestructible!!!!!
$100 for a set of 4 at PYP.
