I currently have a 2008 A3 S-line, and still using the 17" stock rims.
The car has been lowered with the eibach sport springs.
I am going to purchase some new rims for this summer, I would appreciate some advice on what diameter rims I should use.
My goal is to maintain the comfortable ride while increasing the rims to either 18" of 19", could anyone provide me with input on how their car reacted to swapping rims to the larger diameter.
Thanks

 

I hate to say it but I think low profile tires like 1 or 2 over size and comfortable ride yields an oxymoron.

Having said that I've found Michelin touring tires quiet and quite compliant, but it's all relative.

 

Hey I've got the exact same model A3 riding on 18" rims, also with a lowering kit, sharp turns tend to yield some rub so I'd advise against the 19" rims, gotta say with the lower profile tire it IS a bumpy ride though
