Maybe there's more than one cause which depends on car setup. I know that for me, the hotter pads in front, moving the brake bias forward, helped for sure. One of my local tracks, Thunderhill Raceway, has an uphill hard braking zone on a turn (T5, going up the crow's nest), where running the same pad in front and back got me ice mode every single time. With XP12F/XP10R, it happens once in a great while.This makes sense to me...but, I am a bit slow. Why are there so many people that run a more aggressive pad on the front? For example, the Sector111 "hot set up" is Carbotech XP12 (front) and XP10 (rear). If you have ice mode issues, this would make it worse, right?.... and the opposite set up might help?
I'm running Nitron Singles, on Sector 111 "soft" springs, on Yokohama A005 slicks.
