Be careful going too big with the spacers since the more your tires stick out the more stones can be flung at the car.

^ This is really something for 991.2 owners to consider.
I recently ran into this while trying to fit a set of aftermarket wheels to my 2018 Carrera. I was very happy with the stock wheels + 5mm spacers front and rear (didn't even really need the rears for the reason stated above), but what the Tire Rack and others said would fit ended up having unacceptable "poke" with N-spec Michelins (I'd be worried about the rear fenders...) and looked only a bit better with the "weaker" fall-away sidewalls of the N-spec Pirellis. Looking at Tire Rack's site and toggling between the same wheel for 991.1 and 991.2, it looks like most of the wheel industry missed the offset change. Rear wheels offered for the 991.1 and 991.2 are listed with the same offset. In my car's case, the stock rear wheel's rear offset is ET76 while the aftermarket wheels said to fit the car were ET62. That's like adding a 14mm spacer to a wheel and tire that already fills the fender rather nicely in the 991.2.
So what's good for the 991.1 is not necessarily gonna work on the 991.2. Several folks swore the ET62 wheel of the same size would work, and that others are running them on 991.2s—and I believe them, as there's a car in Europe that is, and is being tracked—but it looked a bit juvenile to me real life and, in technical terms, +14mm makes me uncomfortable in this application. Much as I like the design and technical advantages of the wheel, I decided to stick with the factory Carrera S 20s for now. Custom wheel makers can of course account for the 991.2 offset change, but it may affect wheel design (which is why the factory 991.2 NB rear wheels are so flat-faced). My hope is that wheel makers will introduce proper rear wheels for the 991.2 with an ET of 72-74~ mm—as they already have the fronts. Otherwise, they're missing the other "half~" of the 991 market...and all Carrera T customers.
So...be sure to look at the offset of any wheels you consider, and remember that the spacer setups that work for a 991.1 may not work with a 991.2. I view 5mm as the max for the 991.2 NB rear, and have run the factory 5mm spacers all around. Visually, the front would look better with 7-10mm or even 12-14mm spacers, but I'd have to get comfortable with the technical impact of that before moving up from the factory 5mm spacers or maybe aftermarket 7mm spacers up front.

They have a GT3/GT4 style wheel called PGT.

Ordered some spacers today, after doing some measurements on the car, ordered 17mm for front and 5mm for rear with appropriate Titanium Bolts.
On the T (991.2) the Rear is pretty good and close to the fender lip, so 5mm would be enough. but the front is almost 1.2" tucked in, so it needs a lot.
Opposite of 991.1

Sorry I can’t post photos from my phone but I’ll try.
I went with 15mm front and 5mm rear on my type II C4S. I also added a 315 R888R to rear and I still could have gone out 5mm more but am near perfect where I’m at on my Sport Chronology wheels. The fronts needed more than 15mm but plan to try to get a 265 up front if I can find something other than a Hoosier. Over all it looks dramatically better especially since adding the Eibach Sorings. I do wish the ride was maybe 5mm lower but like the handling results from eibach and techart and hr feedback did not sound good so happy with the choice.
spacers and bolts are black and also found security locks that work from FVD or something from Germany.

Also, that’s looks very tight in the front. I would think the tires would rub at full lock. No rubbing?

Agreed. HRE's recommended fitment on the front of my 991.1 resulted in an increase of 12mm of offset and it looked just right to me (considering a combination of a half inch wider wheel and some additional offset: 9.5" and 45mm offset)

But its easy to swap as needed. Right now the front gap is too much.
