Will these specs work for a B6 A4 and how flush will they come to the fender or is it too agrresive and will stick out a bit?

Front- 30 offset, 8" wide
Rear- 27 offset, 9" wide

 

sounds too agressive. that 27 et in the back would most likely rub. 30 in the front as well. are you lowered? that increases the chances of rubbing. i dont think you should go lower than 32. you also have to make sure you can clear your brakes.

 

Can you tell me the stock offset on a set of OEM 17's? I am looking for another set of wheels and don't know what will fit. Car is standard height...Avant

 

stock 17s are et45
