Info originally available from Beavis Motorsport
same for NC available?
Hey Rick, good suggestion, I’ll see if I can add some. I’ve gathered all of these from various forms & pages across a few different communities and put them all in one place. This was originally just a file I had on my computer since I mainly just do NA/NB Miatas, but after sharing it I think the NC would be helpful, too. Stay tuned!
