I have a 2011 GTS with C/L wheels and the info was found on the outside edge of the wheel hub where it attaches to the rotor/hat. Should see it by looking thru the spokes with a flashlight (if it's there).
GTS CL wheels : 51 front and 48 rear : identical "wide body " wheel widths and offsets as the 20 inch 991.1 Sport Techno and Fuchs -look Sport Classic 50th/ Club Coupe wheels
vs the half inch narrower Carrera S , Carrera Classic and Sport Design 20 inchers , whose wide body offsets are 51 front and 52 rear
thats why the former three wheels stick out about 6 mm further in front and about 10mm further in the rear than the latter three wheels
Wheel experts help me out! Trying to confirm these front wheel fitments will work on a 991 GTS with center lock wheels... according to willtheyfit.com this is only pushing the front wheels out by 4mm which seems fine given they are already a wee bit tucked in as is. That said I'm trying to find some comparables or someone that has put new CL wheels on a GTS but info is few and far between. Any input or advice is appreciated.
Still looking for some opinions here and trying to find out is if someone is running anything more aggressive than 20x9 +51 up front on a 991 GTS. I have the option of going anywhere from +52 to +47 and may just end up in the middle somewhere.

Any thoughts people?
have you spoken with any of the wheel manufacturers?

Yes and that is why I'm here. The manufacturer of a wheel I'm interested in has recommended a 20x9 +52 for the front... whereas the GTS stock wheel is 20x9 +51. I frankly don't like the recommendation to tuck the front wheel in a bit more as I think it could stand to move out a bit. My assumption is they don't have much data/experience with the 991 GTS (understandable) so they are recommending the same fitment they would use for a GT3. For reference the GT3 front is 20x9 +55 so that is 4mm further out.
Net net looking to see if anyone with experience fitting wheels to a 991 agrees that the GTS front wheel could stand to come out another 2-4mm or so. Based on the lack of response though looks like I'm going to be rolling the dice...

yep .. I think you are breaking new ground here ... I doubt there are many GTS owners who have replaced their OEM wheels (you and me)
personally I dont think an extra 4mm will make a huge difference but that's just supposition...
you might ask if any of the 50th/4S owners have added 5mm+ spacers to their cars and what results they have had ...

did you ever find an answer to this?
have a 2012 997 4 GTS and am having a heck of a time trying to find winter tires...
I run 19s on my GTS (991.2 C2 GTS: 5 lug w/o RAS):
Wheels HRE R101s
F 19 x 9.5 ET 52
R 19 x 12 ET 48
Tyres: Trofeo Rs
F 265 35 19
R 325 30 19
The limiting factor for Offset with these wheels was the clearance from the calipers to the inner barrel. There's a decrease of the inner diameter where the barrel meets the outside wheel spokes ( for increased strength ) Clearance of the inner barrel to the lower suspension points is close but not an issue without RAS.
You can see where the barrel changes dimension in the photo below, near the balance weights.
I've been running these for the the past year - no issues to date.
I love the look of those 19's, makes the car look like a bulldog 😍
