Hi guys,

I'm looking for black 20 inch rims for my 718 Boxster but there are no under 3k.
Now I found 991 Carrera S rims for 1,5k and want to know if they will fit?

  • Rear 11J x 20 ET52

Thank You!

2016 Boxster 718 Non-S
Looks like you got your answer (above), and I think I would agree (or be surprised if it didn't.) Looking online, the 20" OEM wheel sizes is/were 8.5" and 10.5" with corresponding offsets of 57 and 47. If my calculations are correct, the inside of the front 991wheels would shift that by 1/4" (front) and 1/16" (rear) due to the difference in offsets and the wider wheel in the back. I doubt these amount will result in rim or tire contact at the inside of either the rim or the spokes, and of course outside is no issue. That said, there will be some sort of impact to handling, but that's another analysis entirely!

This guy also put on the 911 Carrera IV wheels which I believe are the same size:

Good morning Vince, I purchased a 2019 718 GTS with 20 Inch Black rims, and I do not like them. (No Scratches, No Dents) If you haven't purchased yours, I will see you mine for 3,995.00
