Now that we had the front dialed in, Norrdin and Zinke installed a stock configuration 1-inch solid rear bar that bolts to the lower control arms and is rated to 1,333 pounds. Thinking we were going to see some fast numbers we were surprised to see the car slow down. "The roll center in the rear of the Chevelles is high. Any increase in roll stiffness pertaining to spring rates, sway bars, or improper bushings will cause less traction and increase oversteer. You will also limit the amount of power you can put down in a corner. It will help in a drag racing scenario. Because the bar ties both lower arms together it helps transfer load to the other tire as the weight transfers."
