Those Nankangs look pretty good, unfortunately their 17's are not wide enough for mine http://nankangtyres.com.au/tyre/ar-1/
Have to say that my present Hoosiers are doing well, they are wearing very evenly across the tread with the shoulders holding up nicely, better than any other tyre I've tried. The other thing with Hoosiers is their sizing, plenty of 17" choice in 40 series which keeps the width up and the diameter down to help clear the guards. EG the 245/40 Hoosier is 622mm dia, 235/45 Hankook Z221 is 644, the difference allows me to use the wider 245's on the front, comparable Hoosier rears would be 275/40 only 648 dia.
I'm talking sprints where there is time to warm the tyres up, not time attack.
