Are any of the other GTRs out there doing sprints breaking other brands of wheels? If the only wheels breaking are ROTAs, they're shithouse by comparison. If they break because you drove through a puddle, that's really shithouse! If they break because they're on a 1700kg car running slicks and agressively curb hopping... well, plenty of people would have suggested they weren't fit for that purpose from the start...
sorry, I just don't understand the logic of not blaming the wheels for breaking after such a short period of time.
that's true, but 6 months and approx 40 sessions (that's only about 8-10 track days) is not a reasonable lifespan IMO.
