Nice car, Vegitto-kun. Did you increase the tire size in the back, but not the front?
Admittedly, I have very little proper seat time in a 370Z, but I just spent a weekend instructing in one (and have instructed others in the past). These cars exhibit a lot of understeer (on a dry track). It sounds like yours is doing the same, as the fronts showed more signs of heat after the track day than the rears. The "strings of rubber" is graining (assuming it's your own rubber, not other rubber picked up from the track surface). The bumpier those strings are, the worse you cooked the tires. The AD08 are a pretty decent tire, and they do a great job of combining dry grip and wet grip. However, it sounds like you need a good deal more front tire (and/or a good deal less rear tire).
Slowing down your corner entry and avoiding excessive throttle (and thus understeer) on corner exit should help with the overheating tires. In general, just reeling it in a bit and driving more smoothly and slowly will help maintain grip. It'll also probably help the engine stay cooler, too. But going to a less extreme tire offset will really help with that understeer / the fronts overheating.
