I'd swap with a friend for Corsa...seriously.

 

I like my Corsas too. Eventually I'll get 18" wheels for the track but for now I run the Corsas on both street and track.

I have found success with 32F 36R hot. Even temps across the tire with this pressure. Sometimes I drop the rears to 35psi if the rear gets loose towards the end of a run session. This is with the "street" alignment. I have just had the alignment changed to "track" per the manual and I might have to adjust pressures a bit.

Any higher pressure in the rears and the car gets loose as the tires heat up.

 

both my RS and GT3 arrived with the Corsas....great all round tires....

 

Cool, i stil dunno what i m getting...will find out soon.

 

I like the corsas on my gt3- good enough on the track until I get a second set of wheels. cold temps are more in the 28-30 psi range than hot temps which are 32-38. after a few laps tire psi went up about 5-8 units per tire...just in case you're wondering.

oh and they handled fine in the snow also.

 

I have tracked the Corsa twice I played with allot of temps. I also ended up with hot temps of 32 f and 35/36R. I was getting even tire ware and the felt good at that temp. also excellent wet tire.

 

Got the Corsas and am very happy, much rather them.

 

How many miles do you have on your car? I am picking up my '08 GT3 on Saturday with 10 miles and it might have the MPSC's on it; I don't know yet but will find out tomorrow. Maybe we can trade, with wheels and all since my wheels are also silver like yours. But mine are brand new without a scratch; what condition are yours in?

 

When mentioning N0 "MPSCs" one should always do the double "air quotes". They are not real MPSCs like you can get in 18" size but a neutered version made so that you don't spin out on the way to the restaurant.
The compound is harder and the grooves are bigger.
So if you get Corsas consider yourself lucky. They are a decent tire for a high performance street car and are great in wet conditions on the track. For dry track 18" is where it's at. On the 997 GT3 and GT3RS the Hoosier has been the choice tire last season. Not as much luck with 18" MPSCs for some who tried them.

N0 MPSCs were created so that people who buy a 997 GT3 can brag to their friends how they have "track" tires. Everyone knows how MPSCs are badass and you gotta have big cojones to drive on them. Nobody has to know that the N0 ones are nowhere near to what real MPSCs are.

 

The P zero's worked out well. I actually liked them as much as the MPS I had on the 996 GT3. Took a while to get comfortable with the temps (I ended up at 32F/35R hot, running Neg 2.1 camber front, Neg 2.4 rear and moved rear sway bar to center position.

Not sure if the tires would have stood up as well as the MPSC tires because we only ran 20 min sessions, whereas in PDE's we run 30 min. Here are pics of the event. Thanks for all the help!!!
