1. How many track hours (or days, assuming at least 5 sessions) these tires lasted for you?
2. If driven on public roads only, how many miles these tires lasted for you?
3. Other than being overly expensive, what do you think of these tires?
Cheers!

I have gone through a full set of cup2*s which are my dedicated track tires
If you have no camber plates you will destroy them in about 15 sessions.
I went through my fronts in 14 sessions driving hard and 373 miles on track plus about 300 street miles transit to/from the track
Went through the second set of fronts super fast because I left them on with track alignment and wore through the inside shoulders. (Picture)
Rears still had life after 19 sessions and 600 track miles and 700 street miles when I put my second set on.
I have 3 sessions totaling 150 miles on this set and they are in great condition. My circuit is a granite surface with high wear and they do well.
Couple of notes.
First, Heat cycle them first, either when you buy them or get them hot on the street and let them cool for 24 hours to get the release agent out of them. if you don't, you will get a nasty vibration when they get hot the first couple of sessions and they wear prematurely
Second, watch your temp. They dont do well over 180 degrees. I start cooling when tpms reads 160+ and cool down to 140 before pushing again,
Start at 26 psi cold at the track (whatever resting temp is) and try to hit 32-33 hot @160-180.
They are super slick cold, and take a little bit to get warm.
They stick well hot and give clear audible indication when they're letting go.
