a few responses, then I have to get some work done.
A. I dont recall it saying the skyline was modified, other than in the article it mentioned the skylines had the governor removed. I will say that I dont know, so I can argue that point. Im also not a huge skyline fan, so its not a huge deal to me anyway. If I could find that website again, I would gladly post the link. Thats not the first time Ive seen a list with that fast skyline in it either. In any case, that track is much more high-speed, so I expect a more powerful car to do relatively better. Its not "twisties."
B. I dont know if youre talking about the Nurburing or the Top Gear test. If its the Nurburing one, I would expect rain to have caused more of a difference than .5 sec on that big of a track. If you are talking about Top Gear, .5 sec still wouldnt have made-up the difference between the 996 and the STI even. I also didnt see any ***'s next to it, but here is the link from Top Gear's website, if you would like to try to find some ***'s.

I do see that they say the 911 carrera S test was with a very wet track, but they didnt mention it for the turbo. As a matter of fact, a lot of their tests in the shows are done in wet...it seems like it rains most of the time there. There is no reason to think the other cars didnt have the same issue.
I would consider their test track to be more indicative of "twisties" than a lot of other tracks though.
As for being inaccurate lists, I posted them as I found them. I dont see anything that inaccurate except for the other Ring list didnt show that particular skyline's times in it. Other cars that are shown on both lists show the same times.
And back to my only original point..."exotics" arent necessarily faster in the twisites, or anywhere else, than a well tuned non-exotic. I didnt even have a desire to harp on the 911 turbo specifically in this, since I dont consider it an exotic anyway. It was just a segway into the point.
