the michelin's have a treadwear rating of 80, so don't expect much longevity out of them

 

Psc have a very stiff side wall. Ride quality is poor over imperfect road surfaces. My only experience with the corsa systems has been on Ferraris where I've liked them, but I can't give you a direct back to back experience on the same car.

As mentioned above, the corsas are superior to the psc's in the wet. Esp after some treadwear has occurred.

 

Gene, are you switching any time soon? I am trying to decide between Michelin and Pirelli and would really like to hear your opinion on this matter before I make my decision. TIA.

 

Can I am sitting on a new set of Corsas that will go on once the cords start showing on my Cups. I am that cheap!

 

Ive had both these exact tires on my second set of rims which i use for track days and have also driven them on street for short periods to and fro track and for the odd few days in between changing the street rims back. I personally found the corsas to be a bit better grip wise on track but not by much. They tend to give up on the outer edges (wear out) much faster than the PS cups and dont last as long as the cups so now I use the PS cups for my track days mainly due to the better wear and cost. You really need to be pushing both these tires consistently very hard to get them hot enough to get the best out of them grip wise so for street and driving fast on canyon/country roads id personally stay with street tires (PS2's) anyday as i cant see how you will get them hot enough. Please note that you will need a proper alignment and at least @ 2 deg neg camber F and R, and corner weights, heights set etc or these will not do it for you even on the track. You will come away disapointed as others will be going past you in the corners. In the wet i would agree the corsas are a bit better due to the outer edge being grooved more than the PS cup but that can work against you wear wise when things really heat up in track use. You wont get the same amount of days life between replacement. On the ride, both are much the same to me. Just my opinion.. Eitherway good luck with your decision .

 

I would be interested in your opinion whenever the time comes. I assume there will be some understeer when the cords show?

speed21, thank you. The consensus appears to be Pirelli over Michelin: better in the wet, a little quieter, a little softer.

Interesting discussion for different Michelin N versions, particularly for GT2, if anyone is interested.

how many miles street on a set of these, roughly? Just curious.

 

Real cups, less than 2k miles. N cups, 5-7k miles. Corsas N, ~8k miles, Hoosiers 2 good track weekends. This is from my own personal experience with 3 sets of N cups, 2 sets N corsas and at least ten sets of old school cups/ Hoo hoos.

 

have you had the RE-11's on the track yet? So far, i'm loving these things.

 

Yes, fantastic, as good as N cosas, not quite as sharp as N cups.

 

Neither TireRack or Discount Tires has PS2 for the rear (305 30/19) What happened?

Recommendations just street only have track tires now
