I wish more people would just put big vacuum can on their 370Z brake circuit. With that mod and understanding that our issues are primarily vacuum deprivation you can pretty much get around 99% of ice mode our cars expereince. To date Im close to a year of no Ice mode after being plagued by ice so badly that I disconnected abs for a nearly an entire season while I worked on solutions.
