I have just blown through the OEM Perrelli Corsas with great gusto... They lasted a blistering 7400 miles without showing cord. It's monsoon season here in Florida so in my evaluation I passed on the Pilot Cups - no little cupcakes for me....
researched all of the new Korean rubber but couldnt bring myself to buy Falken or Hankook - came closest to buying a set of Bridgestone Portenza 11s - but I decided on something completely different NITTO INVO - Very innovative tread design with lots water evacuation and a weird looking outer edge. OH & half the price of Perellis.....

If they are good enough for Ernie Bello they are good enough for me:
NITTO Invo Ultra-High Performance Tire Review | The Truth About Cars

Having said that I dont know anyone that has put them on a Porsche...

Going to track the new rubber on Sat so I will let you guys know if they have grip and if they are prone to oversteer...

 

I'm looking forward to see how they perform =) They look like something that would be on a concept car.

 

Had the Nitto INVO's on an Audi RS4 and didn't like them. The sidewall is too soft. Felt bouncy and hard cornering wasn't there. The INVO's to me didn't seem to have it to tolerate the lateral stress.

They seem to be popular with the Z06 and Viper guys.
Best of luck.

interesting - when I looked at the side profile that was my concern too - just looked too rounded & soft - I will let you know after Sat - it does look like a great street tire though - hoping it is quiet... its my daily driver.
