First post on this forum! Yay me!

I'm thinking of picking up a used 370Z and I'm doing my research on the car for track/dd purposes. I'm coming from a fully built and setup 2002 WRX. I've spent some time at the drag strip but mostly on autocross and roadcourses. I was an instructor for a while at Cali Speedway, and what impressed me the most about my car was that I could run it all day on a track and not have to worry about heat, aside from the usual cool down lap, and parking it in neutral with the hood up etc. What I'm gathering is that Z's have a major heat management issue. So to address that:

- larger radiator
- oil cooler
- PS fluid (some say just fluid, others say fluid/PS cooler)
- brake ducts
- obviously pads/lines/fluid

Non heat related:
- weak LSD
- clutch master/slave cylinder
- camber/caster control arms
- various suspension setup strategies to alleviate understeer

My questions for you guys are:
- What about the transmission? Have any of you had any problems hot lapping with it?
- Ice mode on the ABS - does UpRev or anyone offer a solution to reflash the TCU? Aside from workarounds like running weaker pads, what do you do about that? Can you pull the ABS fuse and disable it altogether?
- As for air to the brakes, I read that it has to do with the front aero - has anyone run it without the front undertray to see if that helps at all? I doubt it would do that much, but it sounds like every little bit would help.
- How do the bearings and hubs hold up? Do you see excessive knockback? If people are cooking their brakes all the time, does that mean they are going through bearings like crazy?

This really is a great forum and a wonderful resource. Thanks!
