ifg929,lfg929 : I don't like them. I use the S2 and M2 compounds but won't use the H2 again (except for maybe in the rear). I had them let go unexpectedly a few times on me at the track. It was the middle of the session so they were plenty warm, and I wasn't pushing near as hard as I had been in other sessions so it wasn't due to loading the front or anything like that. They just let go. Luckily I was able to adjust and recover each time but it really drained my confidence in the H2s. Now the S2 front and M2 rear stick like glue and I have never had any issues with them at all. I have 5 sets of them just waiting to go on the bike throughout the year and another set which is currently on the bike.
They all take a little bit longer to warm up, and they definitely cause the bike to turn in faster due to the triangular profile of the front.
I always run 30 front, 28 rear in the Michelins.jafo : One final word of advice for the track,remember to adjust the psi,have not been to a track yet,but on the street the h2 seems to warm up quicker with 30-32psi.Have fun,hope to attend a class/track day soon,funds permitting.
I use a 180x55 on the rear. I have run the other sizes as well in the SuperCorsas and Rennsports. I really don't have anything negative or positive to say about the other sizes. They all work well and I haven't noticed much of a difference in any of them. The Pilot Race 2's have a much more triangular profile than the Renns and SuperCorsas which allows much easier turn in. That took a little while to get used to (it really altered handling), but after a few sessions I was feeling more comfortable with the turning differences.515O : ifg929,
For the rear, do you use 180/55, 190/55 or 190/50?
