Starting my GT3 in sub zero degrees

Yes, it's a Porsche, I get it! 
However, in my book, an N/A engine that produces 125HP per liter with _solid_ lifters is not an engine like all others. That's why I was asking.
Anyway, you all seem to agree that it should not be of any concern, which makes me happy. I really want to start my car and drive it, even if it's only for 100 meters and in deep snow!

Always tough taking delivery in dead of winter where all you can do is stare at it for a couple months.
Porsches are built like tanks. They take a beating and always come back for more

I have found in the last year that my GT3 feels about the same whether it be in the 30's, or over 100 degrees. Even the oil temps don't seem to be effected by outside temps. Very impressive...

When my GT3 was being delivered i had a gopro on my dash in the SUV. Recording the entire thing. Right before they started getting my car out i walked over to the SUV just to confirm it was recording. I could see the red flashing light. Cool! Got home and watched the video. The GoPro **** itself right as i walked away. That GoPro had a date with my hammer.
True story.

Yes, it is very true because of air density. Drivers in endurance races will talk about how during the night the cars really love the cold air both for the engine developing more horsepower but also because of air density they get more downforce. Living in AZ you can really feel the difference NA or forced induction on really hot days. Not a NA car but my M2 picks up 4 mph on the straight at AMP in the winter versus the summer time. NA cars are less susceptible but still prefer cold air.

Tires will be sketchy in the cold that is for sure. I have driven on Cup 2s at 20 F and they were not great so your dealing with much colder temps. The manufacture has warnings about using and storing these tires at cold temps so just be aware of those warnings. Some Corvette guys have reported tires tearing in cold temps, not the same design as the Cup 2 on the GT3 but something to keep in mind nonetheless.
