This is one of those things where if you ask 10 different people, you get 10 different answers. I followed the below on my GT3, figuring if anyone knows, Andreas Preuninger does. With 7,500 miles now on my car, I have not had to ad any oil. I change the oil between 5,000 and 6,000 miles.
>>>I know you're not looking for a discussion of best practices, but this is from Andreas Preuninger (head of GT cars) - thought this might be useful since this is sorta a Porsche recommendation:
"I videoed AP's presentation, and here is what he said:
“I can only tell you how I personally do it, or how we do it at Weissach – for the first 500 kilometres or 300 miles, we don’t drive that car car ever over 5000 rpm, never. From then on, every 200 kilometres, we up the rpms by 500, so we end up at 1300, 1400 kilometres at the threshold before we can really go full throttle, at 800 or 900 miles”
He then went on that this procedure was really important for the GT3 RS engines given their more "delicate" rings - and how important this break in really is for any of their engines.
Another point - he recommended to realign the car after 1000-1500 miles due to settling - especially since the tires are getting bigger and bigger, and more sensitive to changes. The RS apparently is really sensitive around this.
You figure the head of the GT program would give you the straight goods.<<<

Yeah, have been following Herr Dr. Ing. Prof. AP's advice... now at 475 miles and just clipped 5900 rpm once or twice... of course after car warms up to operating temp. Also no big full throttle and varying rpms and no lugging. Also using pdk in manual not auto to avoid low rpm high load conditions....
It's a painfully slow process especially that now temps are getting in 30's precluding driving on those Michelins...
Still, what an amazing sound from the brap at engine start to the crackle/small explosion on upshifts .... nice beast, love the Ti exhaust in sport mode when it suddenly gets deep at around 4500 rpm...
I can only imagine what it's going to sound when hell breaks loose at above 8 krpm...
Nice car... I think It's a keepah!...

I took it easy the first 300 miles to break in the clutch, then began ramping things up until I hit 900 miles and the track. I honestly didn't think about it too much. I've put 3000 miles on the car since December.
