I traded my Dunlops Sport Maxx for Michelin Sport 4S last fall before hibernation.
They are quieter and less harsh on the highway... but the car felt a bit squirmy and less planted at first... if that makes sense.
After logging some miles, even several track laps, I found they feel MUCH better.
I'm very happy and now have complete all-weather confidence.

I have them on my R32 VW- really nice. Just put them back on car the other day. I run Cup 2's on GT3. I don't think the 4S would hold up for a track day. Chunk I'm sure.

Transformed my TTS...the OEM tires were Pirelli P zero.

Could not be happier...excellent street tire and I drive on the aggressive side!

Agree completely. Have them on my GT3 now for daily use. Cups only for to and from track.

Have them and love them! They worked out well in the winter months (I don't drive in the snow or ice), great versus Cups in the cold and/or wet conditions.

They are very smooth and take the edge off the ride relative to the Cups. I highly recommend these tires.

I got them mounted on with my ADV.1 and it’s been great on my .2 GT3 . Why run sport cups around the streets if you don’t have to.

Do they look the same on rim as the SC2's? No stretching? OEM size?

It would be nice to get a little more grip in the wet and maybe some decreased road noise on the freeway.

^^^Notice very little difference. Please visit my insta @albert.blau for a bunch of pictures. The 4S tires are on the black BBS mags.

Although these are N rated (certified for some model of Porsche - probably 991 Carrera S), the specs indicate that these are not recommended for the GT3’s 12” rear wheel. Click on Specifications in the link above and the recommended widths for the 305 is 10.5-11.5”

Tirerack has either made an error by suggesting these for the GT3 Touring or they have made an error by not increasing the width range (as they do with the OEM Cup2's and Dunlops) - hard to know which.

EDIT: I looked at the Michelin site and they also suggest the 4S for a 2019 GT3, but also show the 10.5-11.5" width range - seems like maybe it's this range that has just not been reflected to allow for 12" rims (and maybe they're fine for this use)

This N0 tire was recommended, ordered and installed by my Porsche dealer on my stock rims.
I have confidence they know what they are doing in this matter.

I'm currently running 265/30/20's and 325/25/21 MPS4S on my GT3 (stock headers with no tune, so relatively stockish power given my catback exhaust) and the grip is amazing. I was always a bit apprehensive with Michelin's MPS4S/PSS because I always loved Bridgestone's RE-71R's, but after some spirited driving today - I can honestly say the grip is perfect for street driving.

Got photos? A few people here are worried about the tires being overly stretched compared to the Cup 2s which, in equivalent 245/305 sizing on the 9 and 12 inch wide rims, are wider than typical 245/305 tires including the PS4S.
