good question. I suppose if you disassembled and cleaned after every event, but I would think the dust would still eventually eat the seals up, especially under track use. I know that some corvette guys run without them though. I really think that most of the problem is that the main track I run on, Little Talladega is very short with no cooling zones. About 12 turns and only 3 small straights on a 1.4 mile course.
