How much roll bar or cage is needed for 10.00 & slower

A six point sure have frame connectors too at a minimum. Trouble is they usually are plated instead of tie’ing everything together. My sons car is a six point for now but I see major changes down the road. He wanted to keep the rear seat in the car so it is what it is but seems to work well running some high 10.0’s with my old 408@3200 poundsView attachment 1715793090
Nice, I was thinking of fabbing a set of frame connectors this fall too
