Danny, what you're describing is not ice mode. Ice mode is something that is happening to some guys who have upgraded their brakes with BBKs. What happens is that the larger brakes have so much bite that it confuses the ABS into thinking that the brakes are locking up. So then the ABS releases the brakes! Bullitt5897 got the Alliance BBK, and a few weeks ago he asked if I'd meet up with him to do some side by side 60-0 brake tests and make a vid. I said sure. So we taped off a 100-ft. distance. My car was able to stop in 64 feet. His car would go into ice mode -- the ABS would ease off and allow his car to continue forward, not clamping down again until he was well past 100 feet. So oddly enough, upgrading our brakes on this car may actually backfire! Bullitt's plan right now is to swap out the brake pads to a less aggressive compound to see if that helps by dialing down the strength of the initial bite.
