That track day in August I had a new set of Michelin Pilot Sport Cup 2 (PSC2) tires on the car and I experienced Ice Mode many times before the second oil cooler leak shortened my day. One of those times was at the entry of turn 17. At 115mph. I released then reapplied and was able to slow the car down but I had to go off track to keep from spinning. I was able to talk to a Gen6 Camaro brake system engineer the next day and he believes the Ice Mode was a result of the aggressive Raybestos ST43 pads in combination with the PSC2s. He said the PSC2 tires have a narrow window of max grip where as the Goodyear 3R that I was running previously have a wide grip threshold.
