Unload car from trailer: easier with 997 because you can remove the lip and don't need ridiculously long ramps as I do with the 996.
Remove transportation wheels and install wheels with good tires. Same job on 997 as on 996.
Drive the **** out of the car: this will probably be more tiring with the 997, unless you have abs and paddle shift
Check tire pressures: same on 996 as on 997
Put transportation wheels back on: same
Load the car onto the trailer: same
Maintenance is not something you do during a track day. I make sure the pads and disks are good enough to last at least the entire day. Worst that can happen is typical Belgian weather. Had that a couple of times in 2014 where I end up swapping slicks and rains 4 times during the day. That is tiring.
Mind you I am not talking about racing it.

Appears to me that PFC is "giving away" the rotors with hats to Porsche Motorsports. I base this on the fact that 380 mm front rotors
For the 997 Cup are $549 at MSRP the hats are an additional $439.
Porsche Motorsports will sell you one 380mm front rotor with hat for
$639.
We all know that you do not need to replace the hats each time. If
You you have a 991 Cup and are not racing professionally I can get you just the replacement rotors from PFC and save you some money.
I must emphasize if you are racing on the professional level you need to purchase from Porsche Motorsports.

I run from 2014 with 991 Cup , the car is less expensive than 997 .
The most important improvement is the gearbox : No problems due the "automatic" shifting , in 2 years ( and 60 hrs) we change only the main bearings and stop. No gears , nothing .
I know someone who has in his 991 cup more than 90 hrs in gearbox and engine....
the clutch has the same price of 997 ( + or -)
driveshafts are the same of 997 ..
the Engine can do 80 hours without problems because you can't downshift when you want ....

Yeah I've heard many regaled stories of way more hours running time on the 991 motor and trans...while 50 hrs is still recommended for the motor...seems a lot safer now to push it longer. But of course as soon as I get to 51 hrs my motor will explode!

to the guys running 996 Cups, what are the approximate major costs and intervals?
Currently have a cup modded street GT3, just had gearbox refreshed at a cost of 11K (cup syncros $5600 alone).
How many hours would you expect from the motor and gearbox if doing 5-6 1 hour track days per year? (no more than 15 minute sessions).
Any other major costs aside from tyres and brakes?

Big advantage of the manual box is that the gears wear out a lot slower than in a sequential. My guess is that you'll first notice the synchros wearing out before you actually break a gear.

Something like that indeed, although your estimate for the gearbox seems quite conservative. I think that if you heel-and-toe correctly and if you are a bit gentle with the gear changes (it's no race, after all) you can get a lot more before it needs a refresh (including clutch).

40 hours for me is 5-7 years so I can live with that I think haha.
It seems like there isn't a significant difference between running a 996 street car and a 996 cup (other than tires) if we're talking about DE type events and track days, would it be fair to say?
