This is starting to make a bit of sense

Interesting thread. Come to this a bit late. I sold my 964RS last year and bought 2002 996 GT3 Carrera Cup to fill the void. I am using it for Track days only. It's quite a different animal to the 64RS, as you might expect. Some things you might realize others less so. Turning circle for one, there isn't one lol. This you'll discover whilst trying to negotiate the pit lane, particularly, Brands Noise test area becomes a challenge ! Actually you will discover it the first time you put it away in the garage or on the trailer. Noise can also be an equal problem. My car register 107db static, Cargraphic Cup side boxes have cured that one. Add these together throw in the paddle clutch and simple getting around the pit lane becomes err interesting !
But get it on track , get the tyres warm and everything else is forgotten and forgiven, it's a hoot. Oh except for the mirrors which coupled with the halo seat make vision interesting. Ok once you're up to speed(as nothing much is going to come past) but whilst you're still learning the quirks of running slicks, or bedding pads at the track it's a little concerning!
Trailering is a pain and comes with issues you might not realize but otherwise It's all good and i'm enjoying it so far. But I really need some instruction to get the best out of it.
Too early to comment on running cost. I have spent a bit on basic refurb/service bits. So far, new rear discs and pads, new rear air jacks and rebuild of front air jack (done by Sobek) New Cargraphic pre silencer boxes, new front splitter (yet to fit, it's hard enough getting it off the trailer without it !) Replacement lance and air bottle it didn't come with one. Fresh brake fluid after each of the two days that i have managed so far. Motor and g/box oil + oil filter (not yet done) and a new front wheel bearing. New slicks are on the list of wants. I picked up a puncture at Oulton. I have been using the old rubber that came with the car, which is grippy enough for me at the mo and I know of others using the part worn route for slicks. I will try and do a break down of costs at some point.

What makes the Cup cars sound so different to the road cars - Is it the box or diff? https://www.youtube.com/watch?v=I3i-8Z9IuJU
Sounds bloody awesome!

Picking the car up sometime next week. The first thing I will do is drop the rev limiter by 200 rpm. This should take a lot of load off of the engine. Then I'll run it for a day and see how the box feels. I think that you can mitigate against a lot of mechanical wear for track day only use. Tyres will be more of an issue. Currently not sure whether to stick with the Miche's or go with the harder Dunlops. The Pirellli are also an option. This is the biggest trade off because tyres are the largest single factor in outright grip but the car costs a fair bit to run whether you are wearing fresh or old rubber so one has to weigh up the fun/performance/economy formula ,and it's not as simple as it seems,,The Mich and Dunlop geo set ups are also very different and the driving style required is different for each so I do need to kind of make up my tiny mind and stick to it.
An update for chaps looking to take this route.
Tyres are becoming a little issue as Dunlop no longer make a rear that fits an early 997 cup. Michelin still make the tyre but it is no longer main stream as the current Carrera cup car runs wider rubber so stocks may be an issue. I am shaking the car down at Silverstone on Tuesday so Pirelli are my only current option which is a tyre that I have no experience of.
Mechanically the car appears good. Only 20 odd hours on the engine since a Parr rebuilt. Haven't run up the gearbox so can't comment. The car has not been run for a while so the brakes will need bedding in. Have removed the auto blipper and returned the gear selector to standard.
Will run the car initially in old rubber, do some gentle laps and get a feel for the set up and get the cobwebs out of the brakes. Then we will fit the Pirelllis at the end of the day and push on a bit to check the chassis balance and get the brake balance sorted out.
if anybody is booked in, I'd appreciate some feedback on sharing track space with car. I am mindful of the closing speeds and keen to try and not spoil other drivers enjoyment of their day.
Will report back after Tuesday.

Best of luck for Tuesday Steve. I would have come along to watch but I am heading to Wales for a couple of days on Tuesday morning. Look forward to your report back. Have you stopped tracking your 996 RS? I just had mine put back to standard and completely restored to be factory fresh. It is looking beautiful. Took delivery of the 991 last Wednesday - what a contrast. Two cars with the same name but so different!!
Hi Steve as you know we ran the Ferrari on Pirreli , and had a lot of little issues ....... as have to start at very low pressure ( 19-20 ) as if start at normal 24 ...... when they heat up after 8 laps or so they suddenly go off .......this was advice from Glynn G and seems about right....
For you guys looking or looking to run early 997 Cups. Pirelli tyre combo's are.
If you are an experienced 997 Cup driver/racer
Front DH 245-645-18
Rear DH 305-680-18
If you are not experienced
Front MH 245-645-18
Rear DH 305-680-18
The DH is a hard compond tyre that will need working more to counter understeer. The MH is a medium compound tyre that will help turn in if the driver is not confident on a heavy trail. Experienced drivers will probably get a graining issue or a little oversteer when using the medium fronts.
Aparently the pirelli does not suffer from wear like say the Michellin does but suffers from multi heat cycles.
Due to restricted time to organise myself, I shall be running MH fronts when i fit fresh tyres in the afternoon - Shall report back

Have you tried the Hankook slicks? It's a good tyre, good feel and progression, similar degradation characteristics to the Dunlop but perhaps a bit grippier. The only downside to them is that if you overload them (i.e. hold a slide or keep the lock on through a lot of understeer) they take a few corners to come back to you, which I can't imagine is an issue for your use.
They must have sizes as they're the spec tyre for the Creventic 24h series and there's loads of 997 Cups in that.

Indeed, woeful, fitted pair to my track m3 with Dunlops at other end, wow they were bad! the Dunlops however were mega.
I had a race at Zandvoort last year where it started raining on the green flag lap and I stuck it out on slicks... It rained for nearly an hour and I was still lapping a chunk faster than all the other cars that stopped for wets after about 15 minutes! Ended up holding the lead in the class with only Cor Euser in the Lotus who was shadowing my approach 20 seconds back, but 3 laps ahead of all the other GT4 runners!Only pitted when the standing water made it too high risk, and didn't go any faster on the wets for the 20 minutes the car unfortunately lasted after we changed!
