Pilot Sport Cups as street tires

Listers,
I have a 996 GT3. It has the Pilot Sports street ires.
I've just learned in Excellence that the 997 GT3 is equipped with Pilot Sport Cups (ie, street legal track tires). This might account for the 1.4G figures I've read as the 997GT3's cornering ability.
I'm putting the Pilot Sport Cups on my car this year for track use -- previously I used the street tires.
QUESTION: What longevity are people finding with the Sport Cups as STREET tires??

I have 2.5k 50/50 street/track on my PSCs, which are identical to your 997 GT3 PSCs. Still plenty of tread, but they're probably heat cycled to death. I'd expect less than 5k if all street driving, less than 3k if street/track.
That said, you could toast a set of PSCs in a 60-minute session with some hamfisted driving.

They aren't bad on the street but will wear much faster than the street tires. Remember the MPSC's that come stock on the new GT-3 are NOT the same compound as the MPSC's that track junkies use. You can tell by the "N" in the part number. The Porsche version of the MPSC has a different compound that allows for better wear and wet traction.

I did three weekend track events, plus normal street driving and got 2,500k miles. What is critical with these tires for both maximum performance and longetivity is proper alignment. I did NOT have the best alignment; my car is set up for a compromise between street and track. Michelin has alignment values on their site or Tirerack that are best. I found you have little to zero time after they are bald before the tire deforms, unlike street tires. They give tremendous grip and worth the money if you can dial in the correct tire pressures.

Heck, look at the 'dorifto' guys, they can toast a set of tires in less time than it takes to boot up your computer. My point, I guess, is that it's hard to put down a hard number to determine how long a set of tires will last.
