So that's what we are talking about right? the example of where the ABS kicks in when not needed and basically any real braking goes away is "ice mode"? And mikes example of tapping the brake and it kicks in super hard is something different?

All cars have brake issues and "ice mode" seems to be a BS catch all. I think it needs to be better defined in order to help everyone.

If it can't be precisely defined, there needs to be more discussion about brakes in general than just blaming the car.

"Trail braking" and suspension dynamics can cause the rear to step out... and are the usual culprits.

After that, you can look at the cars. Bias, fade, computers, ABS blocks, vacuum, lines, etc were all designed for the cars on the street, and work arounds and/or driving changes need to be accepted if you're going to track the car.

It's not really Nissans fault if a street car spins on track. It's the drivers.

....in my opinion.
The hard pedal and no brake pressure are classic symptom of low vacuum and ice mode.

Its a design flaw by Nissan and I completely reject that "all cars have braking issues" There are many car when you put good fluid and set of track pads will work just fine in track day enviroment. It is Nissans fault for developing a car they say is track ready with braking system that has real issues.

Also I had a rear caliper with less than 8000 miles break on track that did cause me to spin. I controlled car and stayed on track but my expereince with 370Z's brakes has been less than positive.

Heck my old 70's era Porsche/VW 914 had better more reliable brakes than 370Z!
