I'm curious, can you run Hoosiers on the Clubsport for DE events? That would save a bit of money too but not sure if the suspension, etc, is completely calibrated for non-DOT race tires. I understand the car will handle and perform differently with Hoosiers compared to racing slicks.

Therein lies the truth, especially amateur cars. Engine and gearbox refresh thoughts posted here are generally nonsense...its a stock gt3 engine without variocam...if its got a blipper then the gearbox is usually in good shape. I had 17000km on a stock 07 for example,before blipper install. Ring and pinion is known to flake over time, skinny gears ie,pre 2011.5 cup sequential can also fail. If they've been updated to thick gears...Good to go...overrrevs 10500 and under, usually fine...loads of firsthand experience with loads of cups...I like cups...no safer racecar and no firewall,engine near my spine...Cayman is showing to be a great car however and I would do a factory race Cayman if I went that way.
yes, and internals on cup are identical to stock gt3. Cup cams(same as street cams) are just key locked as opposed to variocam due to their wide open throttle time as opposed to the street gt3 needing the variocam for their street throttle needs... I didn't overhaul at 17000 either. Car was sold. It went much farther.
Your greatest expenses running race car are transport, track support, and consumables, and there’s little variation on these between Cup and CS. Run what you want. Set a budget each season and play till it’s gone, then maybe sell something you care less about and play a bit more, then reset for next season. That’s racing.
caymans are lower cost, for sure. its not like $200/hour vs $3000/hour running costs. but its a really good chunk less. the couple most costly items just last longer on the Caymans. the tires, engines and tranmissions. they just last longer, presuming no issues. the new 991.2 cups go 100 hours on the engine and 80ish on the trans which significantly reduces the 991.2 cup costs. but having owned both and written checks for both...yeah, checks you write for a cayman are less than the cup by a reasonable margin.

I could be mistaken, but I believe ABS is allowed in PCA on the 991.2s in GTC7, but not the 991.1s in GTC6. I realize there is another catch-all class for modified cars (maybe GTA?).

This is interesting. I have heard the internal components between the cup engines and street GT3 differ owing to the shorter intervals on the cup? Street guys are seeing 30-40,000 track miles (small sample size based on these forums only) with as much street mileage on top of that. I was previously fearful of the engine overhauls but it will take me an eternity to reach anywhere near 200 hours in a cup car (i.e. I will never get there!).
Glen, are you saying you went 17,000km on the engine or the gearbox without overhaul?
On the gear box that would be smthg !!!! Half of that at best I would say.
The 3,6 is a marvel. Would not swap that one for a "crappy" street gt4 engine
Over time tyres are the biggest cost like a lot of others here indicate.
So buy the car you prefer but make sure you have the tyre budget. You can run on crappy tyres but once you have experienced fresh rubber...

996CUP 18500km on the engine on my 1st one before selling. God knows how much the next owner put n the engine before opening. I don't think it's uncommon at all.

I have yet to run on fresh tyres...remaining blissfully ignorant for now

What sort of usage was that? Was it still making good power when you sold it? My engine is on its 2nd rebuild (11,000kms on the car) with about 5000kms/~35 hours on the engine, but it’s not been opened since 2005. Engine does not feel as beefy as my road car 996 GT3 did but road car had 997 TB, IPD plenum, full exhaust/tune and shorter gearing. Cup car is stock standard. Brand new GT4 CS could not keep up with me on the straights. Looks like I may never have to bother with a rebuild at the rate I’m going...250km driven in 2018

The engine was on par with other 2003/05s from racing experience. There were 2 cars that clearly were stronger but 1 with a different exhaust and a better driver and the other one I don't know, I still could take him ;-)
Last leak down test 1 of the cylinders was geting close to critical... our mechanic told us we could keep going, we would burn more oil however. His experience was also that the engine would not lose power, may be the opposite.
Heard about cup cars with 80/90 000 kms ! Oil guzzlers but still going after I don't know how many rebuilds...
I waited a long time, till there was no choice actually, before going to new tyres. It's nice, feels like you are so much better
If you have the budget you won't regret it, just make those laps count, I keep the new tyres for when it matters, qualif, timeattack finals, race. Practice on what's left !EDIT - And you need to take her out more
