I’m starting to think about wheel options for a white 981 GTS. Have 20” Carrera Classic’s now.
Do the GT4 wheels fit?
Anyone have pics of their aftermarket wheels on their car? Looking for examples, could even go for a color!

Its my understanding that 981 GT4 and 981 Spyder wheels will not fit on the regular 981's. Would love to be corrected on this as I see these as the best 2 options.

I think the width and offset of the GT4 rear wheel is going to be a problem. The offset moves the wheel 5mm inward toward the suspension, and then it's 1.5" wider. There isn't enough space before it'll contact the damper / strut.

I need to snap some decent pics to share, but I just mounted up a set of HRE FF01's on my 981 GTS this weekend. Custom dark / satin bronze paint to go with my dark blue metallic car. I think they look pretty good, but then I'm the one who ordered them. I'm not yet sold on the silver / chrome (zinc plated) lug bolts and center caps supplied with the wheels. I feel like the dark color wheel on a dark color car needs dark color lug bolts and center caps. I may be swapping things out in the near future.

Found a friend's pics online. Here's the same 19" FF01 in black on a white 981 GTS.

Do the 981 Spyder wheels have the same fitment issues at the GT4 wheels?

I am still only guessing based on the information I can find for the wheels and my knowledge of how a 10" wide wheel with a +40 offset fits the rear of my 981 GTS. The Boxster Spyder rear wheel is moving in the right direction (narrower and outward), but I don't think it's enough. I have about the thickness of my fingers between tire and strut right now with a 265/40R19 on a 19x10" +40 wheel. A 265/35R20 will be the same outer diameter on the Spyder wheel, but it will be approximately 12mm closer to the strut. That's slightly less than the thickness of my kuckles, but doesn't leave any room for tire, wheel, and suspension flex. If someone had a set of Spyder wheels I could test fit and measure I would jump at the chance, but I certainly wouldn't spend the money to purchase the wheels without having the ability to test fit first.
