So far as you second comment. There's so many variables to be taken into concern there. Size of tires, drop, dampening, and alignment settings for starters. But I'm not going into all that. Just stating.

Mine is within .5mph, verified with my datalogger. I wonder if it will be different with my new tires.
Most stock cars will experience worse understeer with the giant tires in the back only, a set of springs are not going to make a huge different. The stagger tire is purely for looks on the 370Z, it adds no performance edge to most cars. If anything, it hurts it. Try racing at the track with 4 265 or 285 vs. 2 255 and 2 305, you will know what I am talking about.
