I'm enjoying my RT615 right now, still haven't milked everything from them yet. Wear has been pretty good even with plenty of fun drives. My next tires will probably be the Hankook RS-3 or Z1 if I can't get my hands on some R-comps.

The falkens do get a bit greasy after maybe 5 laps on a warm day. I would have to do a slow lap after that and then I would be able to go hard for another 2 or 3 laps.
