1968 Firebird Rear Suspension Question

[stab6902]

I still don't have a great understanding of the problem, but adding a rear sway bar will increase the car's tendency to oversteer (i.e. make it feel "looser"). You'd normally add a rear sway bar to balance the car if the front end understeers (i.e. pushes or plows) around corners. Rear sway bars have no affect on keeping the rear end from moving laterally.



If everything is put together correctly, there should be no perceivable lateral rear end movement, especially with your upgraded parts and what sounds like street driving. Are your shocks adjustable? If the valving is way off/unbalanced (either front to rear or even left to right) that may result in the type of behavior you're describing. Does it act the same way regardless of if you're turning right or left?
