Here are the differences between the 350z Track and my Z (Enthusiast).

Brembo brakes
Underbody diffuser
Vehicle Dynamic Control (stability control)
Lightweight wheels

I'm not prepared to spend thousands on Brembos and VDC - which I would turn off at an autocross anyway I'll just suck it up, and move over to BSP. I just think it's nutty since all models of the Z are in B Stock.

By the way, is BSP my only option or can I go into a different class? Nobody around here competes in BSP.
