^ I concur with Orthojoe. MPSS is a good street tire, maybe even a better overall choice than the MPSC2 since it's good in dry and wet at temps above say 35 or 40 F and doesn't really need to be warmed up. On track, it's just OK, not nearly the same grip as a real track tire like the NT01. And I'm glad to hear that the MPSC2 may have even more grip than the NT01, just wish it wasn't so expensive!

+1. MPSS are great for the street and rain. However, I'm with Pete in that MPSS are not good for the track. In fact, IMO I think they totally suck on track. I know this is the minority opinion, but my experience with MPSS on track has been underwhelming. Based on the many glowing reviews from rennlist I expected them to be phenomenal, but that didn't turn out the be the reality.
There's no way that the MPSS will give anywhere near the grip of the MPSC2 on track. I've driven MPSS on a Cayman R and my BRZ. The grip from NT01 on my spyder absolutely destroys MPSS, and a reliable rennlist member (ChrisF) has found the MPSC2 to grip even more than NT01 on his 997.2 GT3.
I also have hard data logs that show peak sustained grip from MPSS on my BRZ were NO BETTER than the peak sustained lateral Gs from OEM Michelin primacy HP tires, which also happen to be 'sport' OEM tires for the PRIUS.
MPSS. Not good for track. Fine for street and good for rain.

Only question how do you think they will handle on cold wet track compared to the cup 2. From all indications our next track day will be probably around 50F and very wet, which what promoted me to change them before then. If you can provide some insight about this, it will be great. Thanks again. Mark

I had MPSS for my gt3 997.1. Switched to Yokohama adv08neova which I like better for track. Have Pirelli sottozero series 2 for that car on oz ultralegerra 19 inch for winter colder weather. May switch out to OEM tires mpsc2 or Dunlop to MPSS when 991gt3 arrives in jan for Seattle DD use. If snowy/icy will take SUV out.

As for the track I am pretty sure your comments and others who posted earlier are right on the money as they are not really suited well for the track and I really did not buy them for that purpose, but figured why not try them out on the track during my last track event for the year. Good luck and congratulations on your new GT3. Mark

Thank you so much for the info. Very informative. I have strong feeling that's what I will discover when I track them, but that's not what I bought them, and mainly because our track season is over this month and I just wanted to enjoy driving the car on the streets this winter.

I don't have any personal experience with MPSC2 dry or wet, but my understanding is that you will be better off with MPSS in a cold wet track situation. I think you made the right call, but that is just a guess. MPSC2 are supposed to be better in the rain than MPSC1, but I don't know how much better

How long do the OEM MPSC2 tires last with street driving? I'm wondering if I need to immediately get a second set of street wheels / tires for daily driving, and swap in the MPSC2 for the track, or do they have a reasonable lifetime for combo use. At 180 tread wear, I assume they can't be too bad.

I really miss my MPSS as the ride has really deteriorated with the Cup2's. The Super Sports were fantastic in the wet but still a nice track tire. I put 8 track days on my last set as well as some very spirited driving. The Cup 2's have a much stiffer sidewall and make a little more noise. Best of all the MPSS have a wear guarantee of 30K F and 15K R.

I'm probably in the camp too of switching to MPSS at the first tire change interval. Have them on my Audi RS4 and have 20k miles of spirited backroads driving on them and still have another 5-10k of tread life on them. Very advanced tire indeed for the street. For those who fall into the DD / street orientation category, the wet weather capability + the softer sidewalls probably make this a better choice. Basically, in a nut shell, if you decided to buy PCCBs, you might also want the MPSS.

Any opinion on Pirelli P Zeros? I've always run Michelins but my Turbo S came thru with the P Zeros and I have been favorably impressed. 8,000 miles and 4 light track days (100 miles each time out & no much sliding) and useful life. I am also planning to switch out of the PSC2s for the winter as the car won't be tracked again until April-May.
