As far as traction, I cannot comment on long term as I didn't drive much on them, but they are wonderful in track, I can go full throttle early exiting corners without issue, where my old (OEM size) Dunlops will just lose grip. Also, I pushed the car hard on a right corner (while I have half fuel tank) and I got the famous fuel starvation, I couldn't turn that hard on my previous set.
