After a few laps on a hot day using Michelin Pilot Super Sports,they were getting too soft and greasy... so I decided to put new Cup 2's on my R8 V10, and... WOW!! The car was totally different!! It handled corners at far higher speeds with hardly a squeal or screech and no understeer. On the way home, I was concerned about the rain and if the Cup 2's would still grip in the wet. Sure enough it was pouring all the way home, but the tires felt always confident and issue-free (standing water is the only thing you need to watch). Bottom line, these are the finest perform tires I've ever used short of slicks!!
