I agree with flatsixforme, they're a great learning tool, very fun to drive.
As I posted before, I have more fun with those tires than with the Pilot Sport Cups. The car is a bit slower (not that much actually), but just more fun.
For the price it's a no-brainer.
They never felt greasy, and I've tracked them in the Texas summer, I think they're actually doing really good at evacuating heat.
flatsixforme, what pressure are you using ? I'm running them with 26-27 PSI cold on my 17" wheels.

I have burned through a whole set with 95% AX/track miles. They were a perfect fit for me as they lasted me almost a full season and were very affordable. They allowed me to do all the track driving I wanted without stressing about my tire budget. Did I have the fastest tire out there, nope, did they perform well enough for me to continue to learn the car and have fun, absolutely! I would have gone for another set but decided to try the new Hankook Ventus V12's for this next track season...they were slightly more expensive and I hope will have a bit more performance. My only negative observation with the Sumi's compared to other tires I've run is that once they got overheated after an overaggressive AX lap they were very greasy for the rest of the laps in that session. I think the more expensive tires might be better at coping with the tendancy to overheat but that's just a guess.

...anyone else have any input re: cooler climes? mongrelcat
The last time I went out, it was about +30 F, and there was a bit of vibration for about the first 15 minutes. I think the tires may have taken a set with the car being parked for a few weeks.

Thanks again for the feedback guys. For those of you with 17's (tabasco?), what size are you running on the front? I'd like to go 215 or 225 if possible. The car is lowered with stock 7" Cup IIs.

I'm running stock sizes, 205 & 255, and the car is perfectly balanced, no push at all.
I would stick with 205.
My car is a bit lowered (between euro and RS IIRC), PSS9s, M030 sways.

225's and 285's being mounted tomorrow (thanks, Damon).
If the reviews are even close to accurate, Ill give them a shot at this price point. My rear PS2's are shot.
Anyone care to comment on how many miles of "average" (mix of spirited and routine) driving it takes to get them broken in?

A lot depends on ride height and camber ... search is your friend ...

I'm not convinced yet on the colder/wetter street performance. Both should be expected to be somewhat diminished, so claims that they perform "perfectly as if there was no water on the road" are a little bit tough for me to understand, but then again, I wasn't there. My experience has been that they lose grip in the rain, as expected, lose grip in the cold, as expected, and in cold rain, well...that much worse. Note, however that I drive winding, narrow, low visibility, shoulderless roads, so with absolutely zero margin for error (as in trees and boulders are in the right-of-way on these roads) I'm particularly attuned to my traction. I should post some pics of these roads for those who don't encounter this stuff twice a day with lawn crews, utility trucks and other assorted vehicles coming at you...
Now we're talking cold as in ~40F, since Seattle might not be that cold that often (don't know, only been there a couple times) it might not be such an issue.
All that having been said, I am very pleased with the tire overall and don't push it hard in adverse conditions.

I've got a little over 5k miles on my Sumi's (car now put away for winter) and while I have'nt and wouldn't be driving the 993 it in snowy conditions, the dry and wet weather performance has been excellent, and at least as good if not better than my previous Bridgestones.
I have a set on the front wheels, and have had the car out at + 12 F, with no issues.
The last time I went out, it was about +30 F, and there was a bit of vibration for about the first 15 minutes. I think the tires may have taken a set with the car being parked for a few weeks.

The previous year we had 3 solid weeks in December where the temps never went above freezing, so I really expected to have to mount some Blizzaks or Hakkapeliittas on my Cup-II's to get through comfortably.
Thanks again.

These cars are amazing in the snow. I had Blizzaks on my C4S for a couple of winters and the car was on rails in the snow. C2s are equally impressive. You just have to watch it when you drive down hill as the weight bias can make the car twitchy. If you don't have snows already, try the Nokian WR G2s.

I looked at the sizing for the Nokians and couldn't find a tire that would fit as the rear Cup-II's are 9" wide. At one point I was actively searching for a set of 16" diameter wheels, thinking that I could find a set with smaller widths, maybe 7" and 8". I think maybe a set of four of the same either 16" or 17" x 8" wide, and then using the same tire all around might be the ticket. But before I could track any down December has passed with no snow in sight, so,,,, next year.

>> Although we do not make a rear tire option in the WRG2, we do make the front and the rear in the WR. The WR is the only winter tire rated for Porsche and carries the NO designation. I would run the WR in the front and the rear.
Thanks.
