What I found that was causing the ice mode was that the rear brakes were stopping the rear wheels/tires faster than the front. Because of that the car would release the brakes causing the "ice mode". This was from my brake test last year. I mean we tried everything from pulsing the brakes to me standing in the car on the mothers. Once the rear tires locked up or got really close to lock up "Ice Mode" came into affect. I think because of the bias in braking power from front to rear it causes this affect. we tried it on a stock car with upgraded pads and lines and my car with the alliance BBK. The BBK under the right circumstances was able to trigger it alot easier since we were running bigger rotors and calipers in the rear... This also depended on the ground composition as well... if it was dirty and sandy it happened a lot faster. If it was clean it didnt happen at all on the bbk and stock. With all the weight shifting forward under hard braking the rear end has less friction from the ground under braking thus allowing less effort to stop the rear wheels and causing Ice Mode...

My hypothesis on the solution is to run a stiffer front than rear bias and to run less aggressive pads for the rear.
