It is what it is. I'm getting a brake upgrade regardless.

Correct, they are a lot more "brake" (physically in size) than many cars on the track. However, their fade characteristics are fairly scary compared to many other cars. It tends to come rapidly and without warning. This may be a symptom due to PROFESSIONAL drivers pushing it harder, faster - a novice may take longer to heat them up and in turn, overheat them. But the potential easily remains that they can and will fade quickly compared to other cars - even others with smaller overall physical dimensions.

RCZ and I believe TravisJB have both experienced this - they called it "icing up".

BTW, the swiftness in the fade was evident in the Car and Driver test that caused the NISMO to crash - it came on so suddenly and without warning, they COULDNT safely pull over. Scary!

Yikes!

Well, the OP has sport brakes already anyway, so he'd probably be ok getting oil cooler and pads/fluid/lines before tracking, wouldn't you think? And that's not all that pricey compared to replacing the brakes.

Ice mode is not heat related. It's a failure mode of the z's abs controller.

The issue with the sport brakes is the way the calipers trap heat, failure is sudden. Theres almost no fade before near-total failure. It's a confusion issue.

Ahh, very true, I remember now. Sorry, been a while since I talked about ice mode.

Either way, brake fade comes sudden and without much warning.

Yep. It's almost definitely a caliper heat handling defect. Guys swapping to a different caliper with the same rotors have seen good results.

Ice mode is a whole 'nother issue...not even gonna touch that.
