The association I pull with does not have much of a diesel class... Right now it is your either in the 8050 mods or everything else. I'm trying to get the guy that runs it to step up next year and let us run for points. I want a set of rules that would allow everyone to run with out making it to broad of a range... Pretty much I have to put everyone into two classes... Full on puller or daily driver What I have done is taken the NADM 2.6 rules and modded the a little but. Our 8050 class is kinda like the 2.8 class. I'm looking to make rules for the "street diesel class" what y'all think of these? Are they fair?
