wondering how much offset different is too much? OEM is 52mm on my 20' wheel and I see lot of people going for 45mm or even smaller offsets, thus the question
35mm seems to be the reasonable limit (what I run in Winter due to A5 hand-me-down). Best to stay closer to OEM for as-designed geometry.
Spoke clearance of brake calipers, especially larger fronts, is the most critical element however. Some aftermarket rims require spacers for same.
Note that a smaller positive offset number equals rims more pushed out toward the outer fender. So non-rubbing clearance is also critical.
Note that TireRack offers an 18" BBS rim at 35mm. Again, closer to OEM is a better as-designed geometry choice, but they have approved same. BBS SX Bright Silver Paint

You are running A5 wheels on your TT. Would my 18 inch OEM S4 wheels work on my TT? Sounds like they would. Thoughts?

thanks for the explanation. how do you know if a wheel will clear our front calipers, other than go to a shop and try?
I'm actually running aftermarket Rial DH 18" rims from my A5 (and allroad; used Winter only). I added plastic concentric rings for the TT's smaller hubs, just on the off chance there might be some vibration but the lug pattern is of course the same. Since my Rials were at that time built to Audi spec's in Germany using the same process I would think your OEM S4 rims would work great.
There is actually more spoke-front caliper clearance with my Rials than my OEM 19" blade style rims. The Rials are just about flush with the outer fenders and no rubbing issues.
Given Michelin Alpin snow tires and 18" rims my Winter ride is a bit more comfortable.
