I live in the driest desert in North America so rain isn't such an issue.
I am going with Falken 615s based on what I read in GRM and the pricing.
The 615s were a good a bargain, combined with endurance and being predictable on the limit. My son will use this car at some track days and he is not as comfortable with the ragged edge as I am. Naturally I've traded this for some ultimate grip.
