Iirc they have a stiff carcass so are designed to 'squash' when in the corner, where Pirelli have soft sidewalls and 'collapse ' more under braking but not move much when on the side wall. I'm all for a bit of two wheel drifting but like my tyres to stay put lol
Were you on UK tracks @bradders or did you find they were moving too much in the hot as well? I much prefer the Dunlops for the stability but I didn't want to use them earlier in the year on colder tracks for that reason. In the warmer weather I find the Pirellis spin up a lot more than the Dunlops, apart from the first couple of sessions when the Pirellis are super sticky.
