The Kumho V710 usually lasts about 50-60% more runs than the A6. You description of the two is right on. The Hoosier has more overall grip, but does not like much slip angle. The Kumho likes more slip angle and gives more feedback of what the car is doing. . .

45 lbs is a little high for the stock suspension. I was running 38 all around on the stock suspension. I got 50 runs out of the tires, and about 25 of them were on a lot we call "The Cheesegrater."
The A6's are suprisingly indifferent to pressure. At Nationals last year there were people running as low as 24 lbs and as high as 42 lbs in the A-stock Solstices.

on the stock suspension i would be shooting for the 45psi range on the front to help with the poor geometry. even with good alignment i'd be at or above 38psi on the front.
I'm not sure i'd say the a6's are indifferent to pressure settings. a couple psi can really change the balance of the car and 10 psi can cut the life of the tire in half.

One thing to consider is the length and content of your runs. We get probably 50-60 or so good runs on a set of Hoosier A6's, but many of our local events are 30-45 second courses with many transitions and few long high speed sweepers. If you are running on a road course you will probably have more high speed sweepers that will eat the edges up real fast.

I'm sure ultimate grip is given up, but I believe I'm slightly quicker w/ the 710s for the above reasons...
And, I KNOW they last longer
BTW, I can run 33-34fr & 31-32rr (cold) w/ no adverse wear on them.

Yep, that sounds like a good place to be for pressures on the Kumhos. The Hoosier A6's need a little higher. The Hoosier A5's and A4's need ALOT higher . . .
As far as what's faster, datalogging has showed us that the Hoosier A6 is about 1/2 second faster on a 50 second course, even though it FEELS slower. . .
That is on our particular setup. YMMV. . .
