Hey guys, in this test the 370Z pulls only .94 G on the skidpad:
2010 Ford Mustang vs. 2009 Nissan 370Z Comparison Test on Inside Line
So if it really does .99 on a track, and .94 is the median (until I can find a lower skidpad result, of course), then it only does .89 on the street! Sounds good to me.
