I see the flyer states "NHRA rules will be enforced". The "general race rules" on Thunder Valley's web site state "Any car running faster than 11.99 must have a roll bar, 5 point harness, and a fire jacket." I assume the track's rule will take precedence? (11.99 vs 11.49). I have not been to the track since all my recent mods - may or may not be an issue for me.
