Is this legal?

It can be replaced with an aftermarket unit but the aftermarket unit can't be welded in!

Jeff, what brand of bar did you start with?

Chris, it was originally a MidSouth Race Cars piece. Not sure if they're still in business or not, but you could do the same with any Mustang anti-roll bar.

Take that sucker off and see if you can't push the car side-to-side without the tires moving. That is sway. As I said before, accurate or not, go ahead and call it what you want.

[Stocker 2]

Cars such as a coil spring Mustang or Chevelle do not use a panhard arm because the rear control arms are set at an angle to the centerline of the car. The angle of those control arms stop any sway. Any coil spring car that has the control arms running almost straight forward needs a panhard arm to stop the body from swaying sideways and keep the rearend centered under the car.

Both type setups can take advantage of an "added" anti-rollbar which stops the body from rolling or torqueing over on the suspension. Lately a lot of coil spring GM cars like the Chevelle, GTO, GS Buick, etc have bolted a large tube between the lower control arms tying them together. This is a beefier takeoff on the factory bar that was on the some of the original performance cars. I was told this setup is accepted because it bolts to the lower control arms.

I can't take it anymore.......

Panhard bar = poor man's watts link and is ONLY used to latterly locate the rear end housing under the car.......

Sway bar = anti-roll bar = stabilizer bar and it is ONLY used to control body roll by applying pressure across the vehicle.....The body wants to roll but because the bar is attached to the body and the links try to twist the bar to roll.......In some types of racing the racers like to have the links adjustable to pre-load the suspension with out changing the spring rate.......

Same thing with the "anti-sway bars = anti-roll bars = stabilizer bars" that bolt solidly to the lower control arms. The bar will always attempt to keep the control arms parallel and prevent body roll....

i think neveryone but Ed will agree with you, i have never heard a panhard rod called a sway bar,

Anti-roll bar = Sway bar ... Check out Jegs an Summit and look for Panhard bar end links. They have them for Sway bars , but, I don't think you will get them to work with a Panhard bar...
Anti roll-bar / Sway-bar controls body roll or Sway
Panhard bar / Diagonal / wishbone / Watts link control lateral movement

Jus sayin.....Pete

Was wondering when someone would finally say that !
