I have to agree with Kim. I bet I could get a SS Cayman into the top ten. IF someone would give me the Cayman, I would take it to Dieters for a full AX alignment, then pay about 20 other drivers a $1k not to run and I would have a Cayman and a top ten time for $20k. Seems like everyone would win

Otherwise, I think you need at least an S class car to really get into the top ten under normal circumstances. The braking ability of street tires is so bad compared to R compound, no amount of balance could really overcome it in the corners, again limited to the grip of street tires, and the Cayman isn't that powerful to make up for it on the straights. Plus, in my experience with a Boxster S, you can't get the power down without R compound tires which is why I think the std Boxster is just as fast at an AX in SS form. The Cayman would really benefit from a few mods, even more than most cars, but still needs those mods to have any chance at an AX.
It is kinda cool to see a new Porsche model that is liked, instead of hated like the last several, ie 986, 996, Cayenne & Panamerica.
