Super pro has been 1/8th mile for years at monster Mopar and their regular program. Pro ran 1/4 mile but switched their regular program to 1/8th mile now. Most of us running super pro (box class) now have our cars set up for 1/8 mile only. I no I do because every track has race at only runs box 1/8 mile.
