Roll Cages: Chromoly VS. Mild Steel
If you cam do cm I would over ms because once you go faster than 7.50 you will need the whole chassis done in cm. So why not save yourself some money later and just go cm now. That way when you need to upgrade to an sfi cage later you don't have to remove what's already there just add more to it. Now on the flip side if you never plan on going that fast I say it's up to personal choice. My cage is a 10 pt currently and we are going to make it 12 pt next weekend. It's all ms and willstay that way. This car will never see a 7.49 do I'm not worried about it. If I go that fast I'll be changing everything so this car would be sold or given to my daughter to race. (she's only 7 now so there is no plan on getting another car anytime soon)
