Default Ice Mode At Summit Point Main

I experienced the dreaded ice mode three times at the NASA Spring Slam on the Summit Point Main Circuit. I am running stock sport wheels with 265/35/19 front and 305/30/19 rear RE-11's. I was also running a custom made set of Porterfield R4 full race compounds (they are awful, noisy, grabby, hard to modulate, dirty...wanna buy my set cheap?) Here are my observations.

The ice mode always happened at the very end of large braking events (turn one and turn five) just before turn in. Before going into ice mode there was no perceivable warning.

It always happened when I came in to the braking zone too fast and needed to sharply increase braking force right before the corner.

By the end of my second day I could pretty much predict when my Z was going to go into ice mode.

Although the ice mode felt like there was no braking force being applied, my 370Z was still slowing.
