hi,
i have 4 speed bars on my street strip '65 GTO...these are the stamped steel units that connect the rear lower and upper control arms. i have stiffened mine. i run a turbo 400 and my 60 ft is typically a low 1.70- high 1.60. i am wondering if i add aftermarket rear upper control arms, or some other modification, if i can ditch these bars. i thought i heard once they help protect the bulkhead above and in front of the rear end from twisting from the abuse of hard launches...i have also heard that they keep the rear end square in the car under hard launches, but i am not sure what they do. i am considering installing a rear sway bar for more uniform bite from both tires. i run a 12 polt posi...any thoughts? thanks
