Not in-house. http://www.pankl.com/
I was under the impression that the 919 axles were in-house bespoke but didn't know about the RSR and R.

I don't know what's standard on R/RSR/919. The GT3 Cup uses a factory axle but some who run the car will upgrade to Pankl via the aftermarket at their expense.

To answer PT3's questions:
Porsche Cup Car Axles made by GKN are approximately $6000 per car set.
Porsche RSR Axles made by GKN are approximately $8000 per car set.
I am told that, due to a variety of considerations (e.g., durability), very few teams used the factory (GKN) axles opting instead for Pankl or Metalore. The last price I had for these two was in excess of $13,500 per car set without Krytox and without Porsche's markup. Further, these axles did not have the very expensive Aermet shafts nor were they done in limited special runs as are the R, RS axles I have described above.
I know of no other third party axle sets of the quality of what is being done for the R, RS other than Metalore or Pankl nor would I recommend any.
The damage from axle failure ranges from minimal to significant suspension damage to a quarter of a car being ruined to worse depending upon where its happens and at what speed.

Just a note for anyone tracking heavily: axles are a consumable and are regularly replaced on our Cups when they time-out. A broken axle at speed is no fun. I've been fortunate to only witness it and not experience it personally.

I don't want to get wrapped up with lap times just yet. I want to first focus on consistent, clean, smooth laps.
I do, however, watch my videos closely to look for areas of improvement.
My thought is I'll start to time myself sometime early/mid season this year as I was about to start last season right before I sold the car.
Also...consider my goal right now is to just enjoy DRIVING. I'm not chasing a time or to beat anyone (just yet!). My career gives me enough action/competition that I don't necessarily need to had any more!!
Appreciate the guidance here. Though, there actually IS a method to my MADNESS!!!!!

Because of the Modulus of Elasticity (i.e., the "sprineness") of titanium, it is not a great material for axles as it may twist and break. In fact, you would need a fairly large diameter axle shaft for it to work in titanium. As such, the weight advantage of titanium would disppear. On the other hand, Aermet is so strong that it can be drilled very thin yet provide very strong axles shafts.
