Must have missed the whole heritage thing or don't understand the meaning of that word. If you think Porsche racing cars have always had center lugs and not 5 bolt wheels, I'll just wish you a happy 12th birthday and we can move on.
I love it when people comment on stuff they know very little about LOL

My, you took your extra-strength condescension pill this morning.
Recalling your post
That's a nice looking wheel for the 997s. I know a few members are running them. PSA - the points of your crest caps should be oriented to point to the valve stem. This comes from Porsche's racing heritage where it made the valve stem faster for the pit crew to locate when making pressure adjustments during stops when fractions of seconds matter.
Let's start with the premise of stopping during a race to adjust tire pressures. Frankly, that's ludicrous. No driver would waste the time for pit entry, pressure check, pressure change (presumably the pressure is incorrect, otherwise why come in?), and pit exit. The pressures would have been determined during practice and, maybe, qualifying. So would a race driver really poor handling characteristics to air pressure such that they were certain the change would be worth the time penalty? No, they would wait until the next tire change.
What about the hub cap or center cap itself? For safety reasons, race cars don't have them unless they're mechanically secured. No Porsche race car has been adorned by chrome dog dishes, let alone with the crest pointing at the valve stem.
Let's expand on the 5 minute Google search I made before challenging your assertion that this practice comes from Porsche's racing heritage. Of course, race cars with centerlocks won't have caps, for safety reasons as we've discussed.
We'll start at the beginning with the 1951 356 SL Gmünd, this example at the Revs Institute. No hub caps and, notably, no crests. Why? The crest didn't adorn Porsches until 1952, first on the steering wheel. It wasn't until 1954 that it was incorporated in the exterior, on the bonnet handle of the 1954 Speedster. It didn't even make it to the hubcap until 1959.
The Le Mans-winning car had wheel spats, so that kinda blows a hole in the "it's faster for the pit crew to find he valve stem" theory
356 Carrera 4 Cam
550 Sypder
718 RSK
904
906
908s and prototypes onward had centerlock wheels
964 Carrera Cup (someone didn't get the memo)
Actually racing
993 3.8 Supercup (these cars have centerlocks)
What about cars in famous races?
La Carrera Panamerica 550 Spyder
Targa Florio, 1973, 911 RSR
Paris Dakar, 953
Paris Dakar, 959
Monte Carlo Rally, 1965, 911
Mille Miglia, 1954, 550 Spyder
The assertion that this practice somehow came from Porsche's racing heritage is, in my estimation, incorrect. I think this "deficiency" of not pointing the shield at the valve stem started on the concours lawn. Some judge wanted to deduct points and made this story up on the spot and it's become dogma. I looked at some European delivery photos, and the practice is applied by the Porsche factory inconsistently. Furthermore, on cars with center lock wheels and caps with Porsche shields, there's no guaranteed way to point the shield at the valve stem. This bulls**t has become yet another way for self-appointed experts to point out flaws on people's cars and denigrate the owners.

Owned my first 911 in 1976, and over the next 46 years there have been several in the garage. In all those years I have never heard this ridiculous notion that you line the tip of the Porsche crest to your valve-stem. This first popped up here on Rennlist maybe a year and a half ago and the fanboys seized on it and ran with it.
And this equally silly notion that race teams use it to adjust tire pressure and save time was started by someone who has never raced a car or done pit for one. Stop drinking the Kool-Aide and use some common sense.
Before you know it, you’ll be saying that the fire extinguisher in the car is there to put a fire out in your car at the track……lol.
I live 20 minutes from the Porsche museum if ya'll want me to take a look at the crest pointing towards the valve stem thing lmao. only on Rennlist, or concours event somewhere
Pointing valve stem is a concours thing... and for OCD Porsche peeps, which 90% of us are. Now, can we get back to pics of 997s? Here's one from a recent road trip to the Avenue of the Giants in CA.

Will my car throw a check engine light if my caps are not pointed correctly? 🤣
