Those photos were only to show cool 350Z's color schemes (sorry it was a bit off topic) - without worrying if they are current race cars - I'm impressed with your knowledge of them all.

Are you going to post some details about the race preparation of your 350Z race car?
That would be very interesting to read...what weight are you running?

No problems with the stock front calipers?
Some people say that 2 or 3 o'clock position can cause pad knock off

(I'm slowly preparing my 350Z for production racing)

I agree it's hard to get the weight down on the 350Z

I'm in Australia and have several options
We have a Modern Sports Car series where the 350Z and 370Z are on the eligibility list in the top class.
Then there is Production Sports Car racing which has a wide variety of cars.

There are two bodies, AASA and CAMS, AASA is entry level and CAMS is the much more developed body that run all out national events
Production racing uses a tight definition of "sports car", can only be 2 door, there are Porsche and Lamborghini's in the top performance class
Modern Sports cars has 2 and four door cars, they have a eligibility list and cars not older than ~1990 and cost less than $150k - they run classes based on power to weight

Hi, we don't do much racing in Dec and Jan because it's our holiday period (and it's too hot)
We race during the year, winter in Australia would be a "non event" for you, LOL
Categories race from Feb to Nov, some once a month, some once every two or three months (smaller categories)

Last year diverted me from my 350Z preparations
I bought a car, prepared it and raced in the Nissan Pulsar (that's a Sentra to you) Challenge, about 21 cars per race
It's a low cost and restrictive modification category
Some video here: https://www.youtube.com/watch?v=S1oGG1EBL30

I won't be racing this year, my workload, team and budget have doubled and I will be travelling 1.5 times a month on average, that does not put me in a position to do justice to my racing (I'll be flying radio controlled helicopters instead).

Next year I'll be racing again, look forward to that.

I've done some modifications to my 350Z:
Tomei headers, hard engine mounts, 50mm radiator, oil cooler, air con removed,
SPL suspension parts, Nismo coppermax clutch & flywheel (overkill)
Harder diff and subframe mounts
I have recently started it using the Haltech replacement ECU - that was cool
Need to install a cage, install ITB's, tune the car, put a low ratio diff in the rear (I have a Cusco LSD).
I will also remove the variable exhaust timing (RevUp) as the Haltech does control it well

Yes, that's exactly what I was getting at, should still be pretty quick but durability is absolutely in question and may force you to use a hard compound
(265 would have been safe)

I fully understand the heartburn around regulation changes making equipment and supplies obsolete - it's hurts

One of the categories I wanted to race my Z in has collapsed and no longer exists which is even more alarming (but I still have 3+ categories to choose from)

It's hot as **** when stationary,
but on hot summer days I can't get the cabin temperature down
I'm going to need a fan and some ducting I think

Very frustrating trying to find a category to fit into and run at the cost and performance level you want to

It's more that our track cars and tyres and brake calipers/pads are able to exceed the factory expected deceleration rates which causes the ABS module to trigger when it's not actually needed.
At the same time your point is very valid, at the threshold things can become nasty resulting in big disappointments (sometimes costing a lot of money).

One set of race pads I used had wonderful bite but very little pedal feel - which puts me at risk of locking up without ABS

I can see your pain!
My Jenvey ITB's are something like 51mm so the 40mm restrictors would hurt for sure
While money would solve the tyre wear problem (having a decent supply of tyres to consume) it would still leave you with less grip
