Roll Cage vs Roll bar? It's suspension if your suspension doesn't keep you RSD

[FETorino]

PT car = street car that is track capable not a race car. So at what point do you do a cage?

I'm thinking a 4 point Bar (I'm not calling a 4 point a cage) will afford some added insurance and even let me run Silverstate GT up to 150.

For a 3-4K lbs car 1.75 120 wall BAR seems to suffice until your get real serious.

Any reason I should rethink this and go full cage? I would like to be able to drive the car without a helmet on the street and not constantly be worrying about hitting my melon on the front hoop

Unlike GW I'm a Sasquatch at 6'4" so head room is always a premium. Hitting my head so often is probably the cause of the brain damage that is drving me to spend so much $$$ on an old Ford
