Every car and track is different, you kinda have to figure it out by trial & error. Of course is helps to get tips on what to try out but in the end it is up to the driver.

What were most of the other cars running that day? If the majority of the other drivers/cars there were struggling to run decent 60ft times, it usually means that the track prep was pretty sh*tty that day.

In your case, shortshifting 2nd gear may help. Other than that I'm not sure what would help because I've never driven/raced a 7AT 370Z. Maybe the others here can help you out.

Bridgestone RE-11's 285/35/19 or 305/30/19
Hankook Ventus R-S3 275/35/19 or 305/30/19

I highly recommend RE-11's.. IMO you're better off with the 285's

Werd. I've got mine set to about -0.6 degrees of camber in the rears. Although with the the RE-11's and the upgraded tires, it actually became more difficult to launch the car (w/o bogging). It almost felt like I had too much traction and the only way to remedy that is to let out the clutch harder and/or launch at a higher RPM. It makes me feel uneasy when you can launch at 4000 RPM then all of the sudden [after the mods] you have to go up to 4500 RPM to avoid bogging at the launch.
