Average chrome moly roll cage weighs around the same as a .134" wall mild steel roll bar.
The added safety from a cage in a car like a shoebox Nova is worth the price and even a few pounds.
It's not just how fast you are going any more, you have to consider the 150+mph bullet on 9" tires in the other lane .

170+Tom! Excellent advice. Many years ago at Union Grove on their Wednesday Grudge Night you could enter a trophy class for a few dollars more. I had to run a 9 second Vega in the final with a new street car that I had dialed in at 19 seconds. The drivers father came over to me and told me to "Stay in your lane because my son is going to be coming real fast" to which I replied "This bone stock slowed down car dialed 5 seconds slower than normal will have no problem going straight, it's your son I'm nervous about."
