the ad08 is symmetrical, so it really should be flipped on the wheel at least once during its life, if not more. since your wheels aren't the same front to rear, make sure they also mount the rears on the front and vice versa. thats one advantage over the nt01, which is not designed to be flipped. also, on dry track days, you can switch your wheels left to right, as the directional design of the ad08 won't really matter.

now that you're on a street tire, try to get to the point where the tires are really howling consistently through every turn. that's one of the first indications that you're nearing the limit of adhesion. push them harder and harder until you begin to feel them breaking loose, then work on making the little corrections necessary to keep dancing on that line of adhesion/breakaway. "cheater streeters" like the ad08 aren't giving you everything they've got until you drive them on the edge of adhesion. before you know it, you'll be developing the instinctive hand movements you need.
Thanks for this as always, very informative! This is the kinda of feedback that really makes a few flamers not really matter.

Thanks again.

I hadn't thought about the 285/30/18, but looking at the specs it seems that they may indeed be a better setup. It's going to be a hybrid street/track at first, with all the repairs can't afford two sets of everything right away. But I work from home 85% of the time, so not a huge issue either.

Thanks!
