Or would I need spacers, my current wheel is 17X7.5 et45.

I'm looking at the rs4 type from the s-line a4.

as on my car, you would need like 8mm or 10mm spacers to clear it.

I'm also considering the RS6 18x7.5 winter wheel... not sure what the offset is though

Stock has 45mm offset with a 7" wide rim. I think that the 43mm offset on a 8" wide rim is okay to clear the brakes calipers, but before you spend the money, call Gary at the Tire Rack. He knows what wheels fit what, and was a good source for consulting about fitment of wheels.

I was considering 17" 9-spoke RS4 wheels that were 17x7.5 with 43mm offset, and I was told that they would have been okay. I went with Avus wheels so my car would not mimic the new S-Line.

Good luck!
