Roll Cages vs. Roll Bars in higher class cars

My mistake when I built my CM roll bar for Stock class was not using a drivers side rocker bar. I thought the fact I had a CM bar everything would be fine. When I switched to SS class, I had the roll bar converted to a roll-cage. Still no rocker bar. In the end, somewhere along the way, the (slightly) rusty floor separated from the rocker, causing chassis problems. Now I'm building a complete back-half (CM) with 4-link. I may not have gone this route had the chassis remained true.

The rocker bar is required now, even on the 10.5 cars
