In a few weeks I’ll be back out having fun them for a proper day.

Nothing really to report apart from the obvious that they’re much noisier and feel heavier in the steering vs the 4S, I consider the feel a good thing. Those who’ve driven with big, flat track tyres will know what I mean.

I do have sone other observations though, not tyre related.

On the track 4WD is much better than 4WD sport.
I tried this for the first time on the 4S’s and the car became much more taily, really lacked stability vs normal 4WD mode.

Secondly, for those trying to get away with the 4S on the track, be careful.
I thought mine looked relatively unscathed after my first putting a few months back, however they quickly disintegrated this time out with a front delaminating.

They absolutely won’t hold up for multiple track days unless you’re a novice. They’re a great street tyre but a big heavy car like the G80 driven in anger will shred them.
The PS4S delaminating on the track is not a surprise to me. They are Michelins, it's their signature feature. Those tires are junk.
