Looking to finally buy a panhard bar for my car. Are there any huge advantages going with an adjustable over a non adjustable panhard? Both will center my rear end correct? or is that one of the advantages of the adjustable one?

 

An adjustable will let you get the rear centered perfect for different height springs or manufacturing differences.

 

Adjustable gives you the ability to screw everything up. It also will allow you to make it perfect if you take the time.

 

A non adjustable is stock length. It will do nothing to center the rear end if you're lowered. It will only be stiffer then the factory stamped piece. An adjustable PHB allows you to move the rear end horizontally so you can get it perfectly centered.
