A lot of people here complaining about performance drop off, but I haven't seen anyone give the manufacturer recommended break in. It basically consists of "giving up" 1 15-20 minute session in return for greatly increased performance life.

Yep.
This has come up several times before.
We used to run the Z214 exclusively except for a trial or two with the BFG.
Just recently (Sebring and NOLA) tried the Hoosier for the first time on Eon's SP2 car.
His feedback is that the Hoosier grip is consistent from green to checkers where the Hankook fades in the last 20% of a sprint and more to your point about "way too high pressure" on some of the posts above...., we found that 34 psi hot is the fall off point for them on a 2600# 944.
What is interesting is that with same spec 245 tire in Hoosier R7 vs. Hankook Z214, the Hoosier has an obvious wider cross section, iirc, 19mm more contact surface.....so really, unless this is addressed, you almost are forced to run the Hoosier in a SPEC class if the top competition is running them or you start at a disadvantage.

I may be the only idiot who thinks this but it does not matter since you can't buy A6's anymore. I thought the A6 was a better tire with longer more consistent life. I think the A7 is faster at first then falls off. The A7 cycles out faster than the A6 and when the A7 cycles out you may as well be running 5 year old street tires.
