First 50 miles ( mine were wet so possibly less if dry) were "green" as I put it, moved about a bit no feedback and a bit weird in heavy rain.
After this though and a check of pressures they have been above excellant in every weather condition, the turn in, grip and feedback is fantastic and when they eventually do let go it's not a sudden loss- you need to really push things to overload them.
Of course road noise etc is not as good as something more mainstream but these are aimed at the semi track people who want the best of dry weather potential, on the same note I wouldn't push things when wet- I never have but I am not shy either of tipping into a corner at speed.
I have 4k on mine now and they drive and look like brand new so I am fully hoping to get a year from the fronts, but I will have to see what the trackday does to them.
I got mine from Camskill
