About the toe settings he did not wrote if they are intended for each wheel or total but usually porsche specify the front toe as total and the rear for each wheel (I use 1.5mm front total toe in and 2mm each wheel toe in)
I think that's about right,

If using the same points then the suggested 92mm front and 257mm rear seem to be really really low...
If that's the case, 92mm really is very low, and my RS with FAL at stock height has less than 10mm of thread left on the front shock body for lowering....
Can you share where the suggest measurament points are from the Porsche document?

That was the document I found on here maybe uploaded by TRAKCAR
Not really easy to reach the rear point on the floor and it s easier to measure at lift puck points but that s where the official measures should be I think
This should be around 112mm front and 267mm rear... I think it might be a little too low but from pictures looks similar at some manthey adjusted cars
On the document it say minimum height front 115mm and rear 175mm... Is that the already track recommended setting or the oem setting? It seems than many rs are adjusted even lower anyway?
No. Both the Michelin N1 and Sport Maxx 1 are slower and wear out faster.
The new ones are faster and last longer.
Old Dunlops don't last two days, they chunk to pieces on day two, Maybe its an RS VS GT3 thing, but I am pretty sure of my results.
It depends for sure on track settings driving style etc...
I had often MPSC2 tyres loosig chunks of outer rubber after some track days and a few end of session drifts
On that track the old dunlops would be really fast but would almost be completely worn after one day especially the front left but they wear in a very perfect way just really fast
In fact my plan was to set the car at Manthey Racing as they did a good work on my 991.1 GT3
But as it s a bit of a long way to go to Germany and I did not want to be in a rush to go there or wait to get the car with agressive camber etc (I already have mpsc2R fitted and I think it s better to use them with some good chassis setup to get most out of them)
I got just as much information as I could and my usual preferred settings to get near an acceptable track setup
I read somewhere that usually the 991.2 gt3 rs was lowered 15mm front and 10mm rear from MR and wanted to lower it about that but we ended up a bit lower than expected so raised it again a little (not much spring thread to lower on front with the lift system but still even 5mm on the thread makes a good difference)
Of course I know the car is different from the 991.1 gt3 rs with spring rates metal bushings etc but still it s the same body weight wheel sizes etc so the absolute lowest settings etc could be similar
My 991.2RS is completely stock. Everything is different from the .1RS, none of the setup applies to the .2RS.
I tried every setup under the sun with the .1RS trying to make it work, never 100% succeeded.
The .2RS I don't touch until I find a reason. None so far...
Can't argue Manthey of course, but I really don't understand the camber they run, with the grippy rubber of the tires being on the outside edge.
Toe and camber are not all that different, if you run new tires.
Rake is the big difference, sorry I don’t know the .2 numbers.
I’ve not driven my .1 RS with new tires but I could never get the nose low enough until I went to 19”
19” really makes the .1RS handle, but as far as I can tell for now they are not needed on the .2RS with new tires.
Mine (just measured after 3k km) were 120/268 so will drop the front a bit. I really liked the balance and front grip. Tire wear is good too, but mostly Ring laps so not super hard on tires yet given my pace.
