WE are running the same rules as we had been. We sanctioned them last year as USRA B mods but it was our X mod rules. We did add the 7,000 rpm limit to them last year and it worked well to even up competition and save money. We are adding the 5 inch spoiler back to the A mod for next year and will probably do the same for the X mod as they look so much better with them.
It's a great class that is growing like weeds. We ran a B in Cruces almost everytime this last year. Lots of X and A mods being built down here. Good times.
