I've tried Michelin PP 2CT's, a Power Pure, Metzler K3's and now Dunlop Q2's. I am most concerned with how a tire does on damp roads because it's foggy all summer here and the roads are wet under the trees in the morning.
The 2CT tire is great in that situation and now I found this morning that the Q2 is also great because I was going around a corner at 7am pretty leaned over and the rear started gliding out. The great thing was it was completely gradual and controllable, no highside tendancy at all, just a smooth breaking loose.
They must be using the silica in them as Michelin is. Next month they get a work out at Laguna Seca on the last track day of the year. If I live through that, I'll post the results and some video including closeups of the tires.
I love the look of a tire that has had 180 hp thrown at it.
