I've had two sets of the RT-615K+ on my car and I'm almost due for another set. I was thinking about going with the 660 but I'm afraid tire life has dropped way off. I only track or autox sporadically which is why I went with the RT-615K+ over the RE71R. I'm also afraid the 660 will be a death trap in the rain and being in Florida this is a concern for me. I haven't read TireRack reviews of the 660 lately. Last I looked I only saw reviews that only addressed track/autox perf and not a lot of talk about daily driving. Now that they have been out for a while I need to read some more reviews.
I've been really happy with the 615's though. Tire life is good and perf hasn't dropped off a cliff to badly with age. So now I need to pick between another set of 615's or the 660's.
