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.
Pro has always been 1/4 at Monster Mopar. As well as being by far the biggest class. One of the big reasons for that is because it’s 1/4.
I think a lot of guys who show up to events like Mopar at Norwalk are very casual racers, not big dollar type racers , or even points type racers at home tracks.
As such, they enjoy getting to make full passes to see what they can run, as much as going rounds.
Frankly John, I know it’s been years since you have even attended the Mopar event at Norwalk. You have complained not enough payout for the entry fee
Personally, I hope they don’t change Pro, Sportsman or Nostalgia super stock. All have been 1/4 there as long as I have raced in it, which has been pretty much every year now since around 2000 or so.
