Anyway you can pressure wash your dusty track?
Our asphalt season starts this weekend too. It's our second season. Last year before the first race we pressure washed thoroughly. Then every morning before each Sunday race we swept the whole track before putting track barriers down. We used sugar water mixed with warm water in a 3 gallon lawn sprayer in every turn. Worked well.
Our parking lot isn't in a place that is near open fields or lots of open soil or dirt. Just an urban/suburban setting so it seemed like weekly dust build-up wasn't a huge factor that a thorough sweeping couldn't handle. But pressure washing that one time was really helpful getting the sand and dirt particles out of the asphalt bed.
Once the track was prepared there wasn't much difference between treaded tires and Takeoff 27's that an experienced racer couldn't adjust his suspension and chassis to accomodate.
