Michelin Pilot Sport Cups
I have a 2007 Z06 that i run at Sebring 4 or 5 times a year. I'd like to have a second set of tires and rims for these times that i can drive to and from the track, maybe 150 miles round trip. Anybody running these in 295/ 30/18, 305/30/19 on stock rims?

The 305's will be over stretched on the stock rims. I bought a set of CCW C10's in 18's all around. Enough for many tire options, lightweight and can clear a BBK upgrade.
I ran Toyo RA1's. They performed great. I drive to the track on them and have 4 track days on them so far. I'll probably get 4 more out of them before there done.
If you don't want to invest is new rims, Hoosiers are the only tires that are made in sizes that are adequate for the stock wheels.

I turn off active handling and do not run in compet mode. I have big understeer issues when active handling comes on when I don't want it.

So far you can use PS2, the 345 will fit fine as they are not really as wide as the number says. It was even found that the contact patch is the same as the GY 325.
I would not bother with PS2. Wait for MPSC.

I have both the MPSC and the Hoosier R6, both on 18 inch CCW Corsairs (11 inch front, 13 rear). There is no comparison in grip, the Hoosiers are far superior for track use, but are not street tires, the MPSC' are. I use the MPSC for street tires and the Hoosiers on the track. The 345's in the rear fit, but I had a slight rub at max bump so I slightly trimmed the lip on the inside of the rear fender with a belt sander. They both are near stock diameter ratios so the computer is happy. I think David Yu has had some issues in this regard with his Toyo 888.
Here are the MPSC's at max bump:

Sorry, I don't have first hand experience with any of them.
I can give you some numbers crunching only: MPSC have 80 threadwear, R888 have 100. That means MPSC are softer and should have more grip.
Also I would prefer to stay with the stock sizes which will be possible with MPSC next year (325/30R19).
Another thing from Toyo.com: "tires stored and operated at sub-freezing temperatures, i.e., at or below 32°F (0°C), will lose rubber compound flexibility and may experience cracking when operated under such conditions. Do not move a car that is in storage with these tires, as the tires may crack."
Probably this warning applies to any very soft compound tires, just FYI.

I'm interested in the R888s as a possible replacement for my RIIs next year. EXTREMELY happy with the RIIs on my '02Z (285/35-18 front, 305/35-18 rear), everything from wear to noise to wet weather performance is outstanding... just be careful in heavy rain or on rutted roads with standing water. I'm happy with the RIIs, but would maybe look into the Toyo R888 also if it looks to be a favorable competitor.
EDIT: At 25.8" tall front and 26.3" tall rear, this tire combo would likely work well for the C6Z also if anyone needs a tire with more grip than the GoodYears and still works OK in the wet.
