GT4 alloys

[AspiratedAspiration]

I have tried searching for the answer to this on here and other forums, but people seem to rapidly go off topic and argue about tyre sizes, cambers and clearances around trailing arms etc.
My question is simply can I put the alloys (20”) from a GT4 on my GTS? I don’t want to put wider tyres on or add spacers, just put my existing tyres on GT4 alloys and put them on my car.
Thanks.

I think the answer is NO.

I had a 2016 981 GT4 with PCCBs and two sets of wheels (road and track).
I sold this and briefly had a 2016 981 GTS, also with PCCBs).

I tried fitting a retained set of the GT4 wheels to it and they didn’t fit - there was rolling resistance somewhere, on either the front or rear - can’t recall which.
And the offset looked a bit different.

I didn’t bother exploring the option of spacers.

Thanks Geneva,
Not sure if it makes a difference, but I was looking at swapping the wheels from a late 718 GT4 onto my 2025 GTS?

i think you'll find the 718 GT4 wheels are the same offset and every other measurement etc. as 981 GT4 wheels. The only difference is the design.
