That is just one and when I Googled it there are even more.

don't mean to hijack the thread, but what do wheel spacers do other than push the wheels further out from the body. Is there any benefit other than the subtle difference in look that some people prefer?

Looks!

Not directly answering your question but I see you have a 2019 T incoming and wanted to give you this thought: While I've used spacers on my previous two 911s, the 991.2 models have the wheels set further out from the factory and they look spot on to me... especially if you have SPASM. Many others seem to feel the same way, especially on the rear wheels. I could see adding spacers to the front but have decided not to this time around.

^ 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.
