My street tires are Hankook R-S2's. Since they don't make those anymore, I'll go to the R-S3's when I wear the 2's out. The R-S2 are 200 treadwear, and the 3's are 140 treadwear.

My track tires are Kuhmo V710's. They are DOT Competition tires. Have two grooves in them all the way around so they are not 100% slicks...just 98%...lol.

I don't want to do anything else in regards to fuel so if it's too high of a boost number then I'll just stick with 9. Any suggestions or advice?

I'd recommend at minimum a Walbro 255 with that boost level, or if it's in your budget, a return fuel system. Fuel delivery overall is much more reliable and consistent with the return kit.

I was going to get those but I'm worried about treadwear. I can't have it too insanely low because they aren't cheap and they'll never see any auto-x time. I just want a bit more straight line traction but need good wet/hydroplaning traction because Florida is known for tons of rain.

How many miles do the Direzza's last?

^^ when it comes to performance tires like that you can really put a mileage on. unless you bought performance tires for just regular daily driving and not aggressive driving for what there meant for.
