the Z2 are the best all round performance tire I have tried if you are serious about track stuff. Coupled with the YYZ springs a big rear bar and some of my spherical upgrades ( to add the trap door oil pan) the sheer cornering force is just amazing.

Wet weather road performance is excellent as well. Downside? $ and wear. You get nothing for nothing.

 

How do you feel about the Zii vs NT05s? I put NT05s on my cobalt a while ago and thought they were pretty decent so I put them on my RX7, but now I need wider tire's. I have eyeing the Ziis because i was recommended the previous gen, but they were between fazing the old tires out and the new ziis earlier this year so I chose NT05s.

Thanks,
