This is what is on the Combined racing calendar for May 2024, as of January 6th.
If you know of a race that include the NSS, NMC, S/S or Stock Eliminator Classes not yet on the calendar, add or check calendar updates here.
The major benefit of putting an event inclusive of one or more of those classes on the calendar is that many travel pretty far to these races. Some (I often do) may stay in the area an additional week if the race is close to a race they’d already committed to going to.
