Nothing last as long as MPSCs tires and nothing takes longer to warm up either. I was a big fan of them due to their longevity but I never had any fun while driving on them. I did figure out how to make them go fast but it was just too much work, and not enough feedback to keep me comfortable.
I almost went back to Hoosiers this year (I have lots of Hoosier experience) but I did not want to run the huge camber and super stiff springs to make them work so I tried the Kuhmo V710 tires and they are AMAZING. Performance is equal to the Hoosier but with some differences.
The car does not require as much negative camber if it's got good stiff roll rate, but more importantly for those of us that run a compromise setup or a mostly street setup the tire works really well with about -2.5 degrees camber and a fair amount of body roll. For a GT3 I'd say the Kussmaul alignment settings would be a really good starting point but you can relax the rear toe back closer to stock. Something less than 20 minutes toe in on each side should be fine.
The Kuhmo V710 in the 17" sizes that I run requires less pressure than the Hoosier and seems to wear better. Also the car doesn't bind up and slow down as much as a Hoosier R6 when you put a big slip angle into the back end which makes it faster through corners if you like your car loose. They V710 is just as easy to catch if you exceed the limit as a Hoosier. Compared to the MPSCs it is no comparison. The MPSCs are only fast when driven clean with very little slip angle.
If your budget doesn't allow Hoosier R6 or Kumho V710s then I would look at the Toyo or the Nitto. Get off those MPSCs, you'll thank yourself if you do.

People swear by the NT01's and say the grip is as good as the ToyoR888's yet last 20% longer, that could be the longest lasting tire then? I wonder how grip is at that point!

I agree! The MPSC's I hated, but I also ran them like 2 years ago, now the Porsche OEM cups are suppose to be a revised compound making them heat up faster, who knows, i'm not willing to give it a shot when there are so many better alternatives out there..

never ran nt01.
R888 has shorter life than RA1, that's consistent for my three sets of r888's. but they do grip more than RA1

After reading all the feedback here and in previous threads, I'm going to try the Hoosiers.
What pressure do you start with and what is their ideal hot pressures?
Thanks again

This will have all the information you need. They do not work well over 40psi.

On my 993, I started at 32 Rear, 33 Front to get to 40 hot, with a relatively loose and stiff set up (600/800 lb springs, RS height, 3100 lbs, 245/285 R6. Although it is a different animal, there are similarities, and it might give you a starting place.

And I also was told my R888's grip better AND last longer then my previous RA1's, I guess time will tell, oh well!

again, from my personal experience after 3 sets of R888 and countless sets of RA1, R888 is grippier, but they do not last longer than RA1. furthermore, at the end state of their lives, RA1 is grippier than R888.

Hoosier Tire Pressures
Just a note on Hoosier Tire pressures, most people don't like the way they feel above 40psi hot at the rear of the car but if you can get used to the way they feel they will be faster at 42-44 psi hot and wear a little better in the shoulder area. I know one guy with a very fast 996TT that sets his best lap times with 51 psi hot rear pressure. 38-40 psi is a good hot target for the front.

It may be high but it works. Last month I had the opportunity to flog my buddy's Cayman S equipped with R6s 245/35/18 front 275/35/18 rear and we settled on mid to high 40s as a rear pressure for best lap times so it is not an isolated incident of high pressure working well. In fact the Hoosier tire guide recommends cars in excess of 3000 lbs (remember to include driver and fuel) use hot pressure 43 psi and above. Always read the fine print though. The Cayman had stock PASM suspension in it so it had a lot of body roll hence the reason the high pressures worked for it. The 996TT is just big heavy and powerful, again a reason the high pressure work well. Cars with less body roll or cars that are much lighter can use lower air pressures.
