Roll bar requirements?

[Andrew7dg]

Ok I bought a roll bar for my car in case I ever run into 12 seconds (plus just to be safe if I ever bought racing seats)

I thought you needed a 4 point roll bar if you were in 12 second range (never raced before)

Now my dad told me I need an 8 point cage and I am not putting that in my car (way too much fab work) but that sounds a little extreme plus I know it is easy to get dsms into that time bracket.

I bought the roll bar from craig from his car

SO there has to be someone here that knows more about this then I do and pleeezzee chime in on this matter.

Plus just reading another one I have the battery relocated into the back, I am guessing I am going to need a cutoff switch? External?
