I have driven about 200 miles on the new wheels and i must say big improvement over stock.

1) Quality of ride smooth and quiet in relation to stock.
2) Response about equal to stock but overall feel is grippier
3) High speed straights improved stability
4) Stopping has improved but that may be becaue of more rubber 225 vs 245

Have not driven in rain yet but hi perf all season should be better than stock.
I will keep you all posted as miles pile on, daily commute 75 miles NY to NJ.
