Fitted 12ss for the first time last month.My opinion so far is that they are quite twitchy and a bit of an all or nothing tyre when cornering,ie either keep it upright or slam it on it's side,but don't go half and half,they didn't like it,felt insecure.Just in the mind i'm sure,'cos no slides.Maybe just me.Anybody come across this?I had 010's before and they didn't feel like that.Might try Diablo's next.
