Understeer Anyone?

When rounding a corner at speeds of 50+ mph, it seems I have to really concentrate to make the car go exactly where I want. There seems to be a fraction of a second of a delay in turning and it doesn't matter if it's a left or right turn. It seems like it's been more noticeable since I got my Michelin Pilot Super Sports or maybe I just didn't notice it when I bought my Z which had Potenzas. I searched here for threads regarding this issue and didn't find any so maybe it IS just my imagination. Anyone else feel this way? It's really just an annoyance but it seems that I never felt an understeer in my '07 350Z.

That's what it sounds like to me.

Keep in mind the Z is a front-heavy car with staggered tires. Its bias is towards understeer.
