Hi all,

Considering getting a 2nd set of rims and tires.

Found a local guy selling a set of aftermarket rims and tires.

“Zuffen”Collection Rims
20x8.5 — ET 45 — Front
21x11 — ET 56 — Rear

245/35/20 — 85% — Front
305/30/21 — 75% — Rear

Came off a 2019 Porsche 911 4S.
Any reason why these wouldnt fit my 17 C2S?

Wide body wheel will be pushed out to far as the offset is different. Like 20mm difference. I am repeating what I have read on Rennlist so others might chime in on the exact reason they won’t work. You can go the other way with some added wheel spacers. See if the guy will let you install one of the rears and take a picture. Post it so we can see just how bad the offset really looks. 20mm does not seem like that much extra out but visually seeing what that looks like would be interesting for everyone asking this same question. Lots of threads on this topic.

Here is a good thread link with proper offset numbers.

Wide body wheels on narrow body 991

Thanks! Seems like a risk to either consider rims that were once on a wide body.
