I was wondering if anyone has seen an A3 with A8 stock rims??
I was contemplating do this, but i think the offset might not work.
Any info would be great on if this is possible. Maybe somebody knows
someone who has done this.

Thanks

 

I think I may have seen one or two with them. The offset will work. Check out hartmann wheels. they are one of [if not]thebiggest audi replica wheel manufacturers. They have a variety of sizes and offsets. but the wheels are abnormally heavy. I want to say 30+lbs

 

Car and Driver used some Phaeton rims (probably pretty similar to the A8 rims) on their long-term GTI, and they were disappointed in the negative effects on handling and ride due to width, weight and side-wall height (as I recall - don't have the article here right now).
