Slow,
please let us know how the Trofeo's work vs. the MPSC's. Got SC's on my tweaked 997 GT2, but not sure if going to Trofeo's would be an improvement. Does anyobe have any personal experience, not just an opinion or educated guess?

I am calling Pirelli Corporate today to find out WHEN I can get some. Apparently they are all going to pro teams and none for normal guys. I am going to have BIG traction problems if I cant get my hands on these or something else like what I THINK they are.
Rest Asssured when I get them and if they work I am buying two sets extra.

I saw your cars a two weeks ago at Pompano, one on a lift, the other being checked out for a gremlin. Nice cars!
Concerning tires-
R compounds are not designed for low temp use. They only really get good traction after getting heat in them. Street tires are actually better for low temp driving (street driving) for the most part, which is why many people complain the Sport Cups aren't good for street driving in the US- we simply cannot get the tires up to operating temps. For 800ft/lbs torque you will have problems with traction no matter what tire you get (I will be struggling even more within the constraints of what I want to do, ask Tom P. at Champion).
Best bet- get the softer, older Sport Cup design if they make it in the right size. Don't go by treadwear ratings for traction/durability- those are very arbitrary at best and downright misleading at worst. If you are willing to sacrifice some streetability use the Hoosier A3S06- DOT compliant, BUT manufacturer does not recommend them for the street. The old Hoosiers used to be nylon belted, then they went to steel belts, and nowadays I have no idea what they are- nylon, steel? If you decide on the Hoosier R3S06 you'll run into the same problems as the Cup tire- higher operating temps for the rubber compound, plus all the negatives of the Hoosier.
I have a feeling the Pirellis are not too different from the Cup tires. They are probably designed within the same parameters so will tend to operate the same way- especially if they are given the "N" designation now or in the future. In the past (and I'm talking about a decade ago) all the R compounds were similar except for the Yokohama 032R which were available in three different compounds- H, S, and SS (or Hard, Soft, and Super Soft). Yes, I've been out of the game for that long...
The other thing to think about is what your use is- drag, track, AX, street, top speed? Some tires are better than others in different disciplines- no tire is good for everything. You have to pick your poison so to speak.
Also consider the footprint- the more water channels and heat reducing sipes, the less rubber is actually contacting the surface. Not all tires are actually sized the same within the same "size" designation- Yokohamas are usually wider than most, Michelins are pretty close to sizing, and Bridgestones are all over the place depending on design.
I know this post probably doesn't help you a bit, and probably creates more questions than answers- but tire choice really isn't easy for those who are actually concerned about performance...

For instance, my ZR1 with 665 WHP and 645 FT# BARELY spins when hammered with Nitto NT05R's on the rear and does well on the strip, the track,and street. My Z06 with the same set-up but 900WHP+ and 825FT# would spin but could be modulated to hold the power allowing the car run mid 7's on the strip and king of the road on the street. However, as mentioned before, the GT2 is not a vette. I would solve some of the problem with a gear change at the differential (I am dead set on using stock size wheels and tires).
Of course, the key is stay off wet roads or at least be VERY careful.
Having read up on the Trofeos, reviewed video, itseems as though they may be the best fit for me. Running the 1/4 (every once in a while), driving on the street, and having fun on the hwy ramps. Again, being very aware that wet roads are NOT my friend. I have read up on the Trofeos, reviewed videos, and it seems as though they are stickier than the MSC. I am trying to find a set and will find out very soon. I will post my findings but would bet my bottom $ they will outperform the MSC on the street, strip, and just having fun. The nice thing being they are hi-speed rated (more so than the Nitto).
If all else fails then I find wheels that will clear my brakes and put me alllow me to run 18" tires of which there are many choices.
Until then, I am putting my $$ on the Trofeo and see exactly what happens. I will post the results.

Hi Slow,
I use Michelin PS2 for the road and trofeos for the track, changing them the night before I go to the track. Have driven the trofeos in pouring rain and they definitely hydroplane if your going too fast. Be very careful in rain -- they are pretty good on wet track.

Thanks - I called Big O and they have no Tofeos. I was told to call Bob " " or Frisby but neither have any idea when the tires will be shipped from Italy. I also called the corporate sales office in the USA and they are clueless. I am not sure what to do. I may call Europe in the morning and try to order some from a Euro dealer. I am at a loss.
