It's hard to diagnose what's wrong from the timeslip alone. Clearly you need to lower you 60' time. Since you have an automatic I'd think that maybe you need to look at your torque converter. Were you breaking loose off the line? If you were then I'd say it was your tires.
"The 300ZX Turbo is a dance; it's a song; it's rolling, roaring automotive art. There is no color that doesn't suit it. There is no mood-lifting chemical substance it can't replace." - Automobile Magazine
