Down here we haven't been able to get rears for months. The factory has been slow to get these into the dealer channel - Im guessing most of their production has gone to the factory for fitting to new cars. I'm now due my third set (I imported the last set from Tirerack in USA).
As this has been a problem for a while for us track types, other kiwi 992 GT3 owners have moved to the 265/325 Cup2 from the 992GT3RS. This trend started in the USA where they also have issues in supply. The 265/325 combo has now been tried and tested on road and track with very favorable results!
They fit perfect (the 992 has wider rims than the 991), they look really good (the Cup2 doesnt have the silly fender lip) and they perform better (wider with a lower treadwear rating than the 992 GT3 Cup N0 and I suspect a slightly grippier compound to help the GT2/3RS achieve their dominance). Better yet they are available and they were cheaper for a set!
Most of teh guys using them I have spoke to have claimed they are getting lap times around 0.5s quicker on these versus the 992 GT3 OEM Cups. Remember the factory set the 992 GT3 NR time on Cupr which have remained the same compound as before but with the wide range of varying tyres the factory have been forced to use on the production line due to Michelins production capacity I suspect that the 992 OEM Cup 2 is not as "sticky" as it could have been (its 200 treadwear vs 180 previously).
It may also be that latest gen tyres formulation is changing to become more environmentally friendly like the 992 GT3 pads that melt because they have low copper. At the track we all ditched the factory supplied pads before teh first outing!
This sounds paranoid but a number of manufacturers are now changing formulation to meet EU directives for reducing the use of certain chemicals. This can lead to a longer lasting tyre but sometimes with different characteristics. A good example from a while ago was the Yoko AD08R vs the new AD08RS...
Ill be getting mine fitted at month end and will post some pics.

Treadwear rating is only part of the story. The OEM cup 2 for 992 is actually 240 rated, same as the last gen track connect tyre, but wet and dry grip has supposedly improved. The OEM Pirelli as an example is 80 Treadwear rated but I am positive the Cup 2 will perform better on track.As this has been a problem for a while for us track types, other kiwi 992 GT3 owners have moved to the 265/325 Cup2 from the 992GT3RS.

I got a set of Cup 2 in OEM size from Blackcircles and my OPC is fitting them tomorrow. Pirelli’s have been good, but expecting more from the Michelin. Will find out at the PCGB Oulton day later this month.
Interesting article here on not all Cup 2 being the same. Construction, compounds, tread design all vary greatly by application.

Generally you cannot compare TW rating between manufacturers. However within same brand relatively speaking it is a guideline.
Going by what those who have fitted the 265/325 Cup2 N2 tyres are saying about improved lap times and lateral grip I think its certainly worth giving a go. I do have a full set of the factory OEM spec tyres arriving from overseas in May (personal import) but I think the larger tyre patch of the 265/325 coupled with the camber Im running (-2 1/2 degrees all round) and the potentially softer compound should yield favorable results. Ill report back once I know more. If they work as well as expected I will likely stick with them...

I’m going to compare the Cup 2 against the Pirelli P zero in the next few weeks.

A slight change of subject, but like me are you lads struggling to find Michelin Cup 2.s for your 992 GT3's I am in Bedfordshire any suggestions as my friendly dealer is at a loss to locate any.
I have 2 new sets of Cup 2 Connect for 992 GT3 that I will need for my own use, one of the dealers I use rang on Monday and said that they have just received a set that I ordered last May. Pm me me if it helps and i will send you there details . They are just outside Bham City Centre.Mad Scientist said:

I had a drive in Friends Touring last week on Pzeos it felt much more friendly for road use than what my WIng car is on Cup 2s, driven back to back on same roads.https://youtu.be/j-TQH79IzR4

Looks good. Never been to Oulton Park. https://youtu.be/j-TQH79IzR4

Had the Cup 2s fitted this morning and completely agree. It’s busier and choppier on the road now, running max negative camber on the front on mine (think -2.8?).It’s nothing horrendous or unexpected, but should pay dividends on track, which is my main use.

The Touring I drove on Pzeros was the complete opposite to what " Harry" drove in his Video on same tyres , pressures were set to 29/32 Cold, It was just like the car in the PH review as in very controlled and tracked perfectly.

Interesting with the set up route you have gone on the 992GT3, I had every intention of doing this but after exchanging views with a Chap that understands the Aero, suspension, chassis on this new car I ended up with keeping settings as stock, but rear wing on full DF same for front, rear ARB on full stiff and front no 2. This completely sorted the Oversteer on the back end in the high speed corners. On the fast straights not a lot in it between what my WP RS would do but the corner speeds are much higher, though some of this may well be down to the grip new Cup 2 Connect which in my experience so far are a good step up on the old ones. Did you adjust the ride height at all?

If i recall correctly mine is -2.8 on the front, -2.2 on the rear. Front lowered 10mm, rear lowered 5mm. Rear roll bar full hard, front medium. Max aero on wing and front splitter. Tow was tweaked too, can’t recall how much.Interesting with the set up route you have gone on the 992GT3, I had every intention of doing this but after exchanging views with a Chap that understands the Aero, suspension, chassis on this new car I ended up with keeping settings as stock, but rear wing on full DF same for front, rear ARB on full stiff and front no 2.

It’s very neutral and balanced for me. Really happy with it. Very even front tyre wear.
Changed the pads to Pagid RSL29, better fluid, running OEM rotors (steel).
I’ve only done 6 trackdays in it, maybe I’m not pushing hard enough yet, but really enjoying it. Looking forward to trying the Michelins.

That looked very tidy ... and .52's is swift !
The best I've managed in my GT4 is .55's ... but the Manthey GT3's at the Oulton RS day were said to be doing .45's ??
Manthey + Tim Harvey is probably quite a thing to see!The best I've managed in my GT4 is .55's ... but the Manthey GT3's at the Oulton RS day were said to be doing .45's ??

I also have approx 2.5 degrees all four corners with the small reduction in ride height that that brings.
If you are driving on Cup2 on the street try the autobahn settings on the door jam 32/35 psi. It greatly reduced tramlining and makes steering more manageable and safer on the road....almost like night and day.
Im interested in how others rotor wear is. Particularly on aftermarket pads like RSL1/29. I have 8-9 track days and 8000 road km on mine and by the looks of it I will get another 2 days from the rotors minimum and maybe 3-4 max so 10-13 days dependent on track and usage. Mine are showing ridges (interestingly the high points are in line with the "simples") and very fine cracks are now appearing 5-14mm in length again interestingly emanating from the dimples. None have joined or reached anywhere near the out edges of the rotor annular at this time so all good. I havent checked for thickness but will do after my next few track days in May....
