i hope they wear well for you. i had a set that i ran for not even a full summer (they came on my 135Ms), and i was not impressed, at all. they wore unevenly, flat-spotted easily and one became a little out of round. i also did not like their breakaway or ultimate grip level (very low).

needless to say, i was happy to see them go. replaced them with OE M3 Conti take-offs that are much, much better.
