700+hp is a lot. I never really thought about what the McLaren model designations meant until my mate took me out in his. I've driven 996 turbos mapped to about 500hp and 997 GT2's with more again. They too have that weird ability to give the illusion that the tarmac ahead is being pulled toward, too fast, you like a rug, but nothing really prepares you for a 720S.

Edited by APOLO1 on Wednesday 1st September 09:21
To be fair I don’t think that Anglesey is a representative circuit to use for comparing these cars. It’s a lovely little place but far to tight and twisty for the performance level we are now at. I appreciate that it’s a like for like situation but it doesn’t satisfactorily prove out high speed stability and aero etc, etc.

You keep mentioning these new Cup tyres, are they not the same compound as the Cup 2s. I cannot find any info on it to say they are different, only they have gone up a size for Porsche GT3 and they have given them an N0 rating which makes me think they are exactly the same.
Have you driven a car on track yet with these new Cup 2s? A good friend does development driving for the maker. He mentioned before i had my car that they were a "halfway house" between the older cup 2 and the more expensive cup 2 R. In my experience with them so far 600 track miles and 1500 road miles they are a lot more more sticky than the ones that i had on my 2RS, 991.2 GT3, and WPRS, they now only require one dial down and sit at 30/33 all day, the downside is that based on track use so far whist they last a lot longer than the Cup 2-R, they only last about 1/2 the track use time as say the ones on my last WP RS, and 991.2 GT3.

Unfortunately no, I don't get to track a car as we don't have any. That is interesting information of which I was not aware. Does the tread still start out at 5.7 mill on these or are they less?
As new they come with 5mm

Cheers
These were 5.7 on the .2 new.
Fronts are just under 5 and rears just under 4 in 8k miles road driving, am quite gobsmacked really as I couldn't get 4k out of the rears on the BMCS which was tuned to around 520.
How many miles did you manage on your first set with your track driving and do you drive it to the tracks or have it trailered?

If I recall correct out of the older Cup 2s on my 91 RS i would get around 4/5 Full Track days before they needed replacing. There would still be a bit of tread on them for road use, but they had been through so many heat cycles they would lose there grip even when hot. These new Cups on the 992, I did 4 Half days so 2 full days and around 1200 road miles before I had to replace the tyres with a set that had half wear on them as a stop Gap. No I always drive to and from the track thats whats so great about these cars.

APOLO1,
That looks a good list with reference speeds on it.
I would like to see the full list?
But if that is a guide that the 992 GT3 is faster than the GT3RS and the other cars listed, it is no wonder they are going at such a high premium.

Does anyone know if the Pilot Sport 4S is now approved for the 992 GT3?

I asked my local Centre but they don’t seem to know.

Without wishing to open that can of worms again, but when it comes to checking and buying, how exactly is a consumer supposed to know this?
You call up which ever tyre shop you use and say I want this size tyre but it has to be N rated for Porsche. They’ll reel of a list of makes and models and you pick one. If it’s not a “track day” tyre but it’s the right size and N rated where does that leave you?

IIRC the rear on a 987 boxster is the same size as the front of a CGT - when you buy an N rated tyre which one are you buying? The one that was rated for the boxster or the CGT and again… how are you supposed to know?

Quick google and I found this

https://www.porsche.com/uk/accessoriesandservice/p...

The N stands for Nurburgring- who knew!?
And you now have A for 992’s!

Load Indexes. They will be totally different for the CGT and Boxster tyre. And I think the computer systems the tyre suppliers have shows more information about which tyres if for which car than the websites. Load index for sat a GT3 would be different to a GTS as the latter is a 4 seater….that’s one of the reasons the Touring can’t be a 4 seater because they would have to so type approval all over again.

That makes a lot of sense... but having had a very quick look at the technical info provided by Porsche for my RS - the load index isn't in the technical data section. Just the size.

They don't make it easy do they!

Easy wink the only N rated michelin supersport was for the cgt. It was technically the right size and N rated for the 987 but you most certainly weren't really supposed to be fitting that!

Sorry, I dont have any more times from others cars to hand for that track, other than the Lambo STO 1.48.6, like 3 secs off the GT3. Whats adds extra weight to those times above IMO is that not only is the same track but the same driver.

I agree for cars like on the above list lap times are important. If you you think about the RRP prices of what the above cars are when new its not hard to see IMO as to why the " Market" price of the 992GT3 is were it is right now.

Does the MP4S in 315 section have a narrower tread width than the Cup 2? On the 325 section for GT2RS/GT3RS it's really noticeable. Looks stretched.

Sorry, I have no experience with MP4S on any car. It was a case of enquiring as to an alternative to Cups that were not available at the time..

You need MP4S in 355 section to get the same tread width as the GT3 RS OEM Cup 2s in 325 width.

Every GT2/RS I see with cup 2s looks like balloons and the same now with the 992 GT3, is there not an option to get the flange on the tyre.Or is there a reason why they don't have it.
