on a more serious note, this thread offered some seriously interesting reading. Unfortunately I still have to do my fist track day with the Z (only 3 weeks away) so I can't offer a lot of interesting input on this ice mode issue. But it sure is a "good to know" before hitting the track. I was getting a bit worried that in addition to the oil overheating, this was another 370Z only track related issue, and I should have bought a used Elise or 911 as track toy instead, but it looks like this issue is not 370Z exclusive. Not much of a comforting thought, but still.
Anyway, I wouldn't mind being able to switch off just the ABS on the track. I have done track days with a lot less technologically sophisticated vehicles and I liked not having ABS:
Not so sophisticated Opel Kadett GSI (but lots of FWD fun, lift of over steer...)
Who needs ABS?? and no, I didn't hit the unfortunate Mazda 323 (protege) in front of me and yes I did have a flat spot on my tires after wards... :-)
I hope to have some more useful input to this tread after April 4th
