Exactly. I drove on them in a standing down pour on an open track day just to learn the track (no one went out early because of the rain.) So I was cruising just to learn the track and started pushing little by little to see where the limit was.....the limit was much better than I anticipated. I was shocked at how good they were in the wet.....Actually the R888 aren't too bad in the wet. Are you planning to drive back and forth to the track with R comp tires? What experience do you have? Depending on the answers to these questions, there may be better choices.
+1 - Same here."The only advantage of R-888's that I know of is that you can flip them on the wheel due to symmetrical tread pattern, but personally, I think flipping tires is a false economy / band-aid for a poor suspension set-up."
I have run Nittos for several years on both an AWD Audi and my Cayman and think they are the most bang for the buck. My track car is also my DD and I drive it to the track so I don't adjust camber at the track. I just have it set at max negative and leave it there. By the time I have too much wear on one side (usually after 4-5 track days) the grooves are pretty much gone and I flip them. I don't think there is much asymmetry left at that point. I typically get 7-8 days on the fronts and as much as 11 on the rears.
