What do they allow you to do, what are their benefits, and are their benefits to using non-adjustable aftermarket units?

How would you adjust them per application? Longer for drag racing, shorter for cornering, etc.

Thanks

 

An adjustable panhard bar is used to center the rear end side to side. If you lower the car using lowering springs the rear will shift to the drivers side. Measure from rim to fender with a yardstick held vertical to check if the rear is centered. I got lucky and mine was within 1/16" after I lowered the car, so an adjustable PHB wasn't required.

An adjustable torque arm is used to set the pinion angle of the rear end.

On a stock ride height car is there any advantage to running aftermarket units then?

 

PHB, quite possibly. It will be much stronger than stock. It won't flex under tight high-speed cornering. Adjustable may also be useful for a stock application because the springs do sag over time and could shift the rear to the side.

I have no experience with aftermarket torque arms, but I will say that the Energy Suspension polyurethane torque arm mount bushing makes a nice difference for traction. It is quite a pain to install though if you don't have the right tools, etc.

 

PHB, as said above, if you cornor hard, or know the springs are sagging. Also if the bushings of stock one had. Why not replace it with better unit?

Torque arm. No point unless car is driven hard, or modified. If the front bushing is bad, replace that.


I put a PHB in when rear bushings went out. Had future plans of lowering. I installed my torque arm when I converted to manual to correct pinon angle, and because my trans didnt come with proper tq mount. So I killed several birds with one stone. But it also made the car handle, take off, and break better. But then I also push my car to its limits daily.
