Hey folks,

After my previous track day, I have swapped my stock P zeros (1:53.5 at Ridge Motor Sports Park) out with Michelin Pilot Sport Cup 2. I managed to shave 1.8 seconds off to 1:51.7 with new tires, and I'm sure there is plenty of time on the table. I personally find 34/36 psi hot provides the best grip/side wall stiffness, and started getting slippery once it goes above 39 psi. After a whole day with 7 sessions, the tire wear was surprisingly well, it seems like the 180 tread wear was no joke :reckon:
After the track day, the uneven wear was not noticeable, and for wet driving it's about as good as PSS, and does not really feels like ordinary R compound tires, thanks to dual compound. Road noise is actually just about the same level as my Stock P-Zero's. Not bad at all! Would definitely buy these again after they wear out, which should be some time later.

Here is the link of my 1:51.7 lap

And a bit of fun when it got above 39 psi, still controllable. Outstanding tires!


Let me know if any of you are interested in purchasing PSC2's for 245/305 (GT3 stock spec) , I bought a few sets since it's on global back order. Text me at 425-686-5008 George

Nice save!!!

I also have the SC2, I didn't go to the track yet but on the street I'm using it with Porsche recommended PSI (31/37 cold) but I get 40/46 hot which is A LOT more than the -around- 33psi hot the Michelin website says to get the best of this tires

So I need to lower them a bit, can you recommend a value for street that goes well and also that I don't lose grip?

Han, looked like a lot of fun! I actually found that the MPSS were about 2 seconds faster than the P0's assuming an approximately 2 minute lap, and bet the MPSC2's are another 2 seconds faster. Its hard to say for sure as I changed to the Pagid brake pads about the same time as the tires.

Jonatan,
I run my MPSS at 28/30 to keep them under 40psi when hot. If you are not doing many track days, I would run them at 31/34 which is the comfort setting. You can let out a few more psi at the track. You probably don't need to worry too much about the ultimate traction from those tires on the street.

Quick hands!

Jonatan

Thanks Jonh's 991!

Han0355, did you leave the wheel "free" to spin until you hold it again to do the "save" on the second video? There's a moment when the wheel is rotating at super speed!. I hear it's not recommended to do that :O. Just asking to learn!

You guys crack me up. Yeah, his hands moved quick, but only because they were so slow to respond in the first place. The video shows the car over-rotating well before any counter-steer. If he'd been quick to counter-steer immediately the instant the rear moved out that would have countered the oversteer. Instead of getting sideways it would have looked like a drift or nicely controlled slide.

Great car, though. What is this, like two videos in three weeks where the car saved the driver?

PS- Michelin Man at Parade autocross was telling me to increase pressure to what I knew from experience to be way too high. Ignore Michelin. Go with what actually works.

Jonatan

On second 9 to 11 (aprox) he's not moving his left hand yet the wheel is rotating. He just leave the wheel "free" I think.

John's 991

I would say its not ideal to let the steering wheel slide through your hands as a regular practice, on or off the track. You just dont have the same level of control and finese possible. But I am also a firm believer in not spinning your car at high speed and whatever you need to do , you do. Style points are less important.

Chris Harris, was that you?
