Diagonal link and panhard bar on ladder bar suspension

I recently went with a friend to look at a car he is interested in purchasing and saw something somewhat strange on the rear suspension. The car has both a diagonal link connecting the two ladder bars and a top panhard bar. Is there any reason that someone would run both systems and is there anything negative associated with doing so? I've been under the impression that a panhard bar was better for a street car while a diagonal link worked well for drag racing but I've never seen the two combined on the same suspension system. Any input would be appreciated. Other than this the car was really nice and I think my friend will be making an offer on it soon. Thanks.


Joe

The both are basically doing the same thing - keeping the rear from swaying side to side. They may however be pivoting at different points and could put a bind in the suspension.

Yeah it sounds like someone went overboard. And as said, they could very well cause a bind if not set up perfectly.

Exactly what I was going to say....run one or the other, but not both, as it is virtually guaranteed that they will fight one another for the control of the suspension during suspension travel and bind things up.

I'd look a little closer at the rest of the car before purchasing, you don't know what else could be done incorrectly.

diagonal link and panhard bar

Thanks for the responses to my inquiry about using the diagonal link and top mounted panhard bar. We spent quite a while looking the car over and taking it out for a ride over smooth, bumpy and curvy roads and nothing else stuck out as obviously being done wrong or set up in an unusual manner. She drove nicely, tracked straight and true, ran smoothly with no overheating issues, stopped quickly and in a straight line with no pull to either side and we heard no odd noises. However, you never know what you're going to encounter that is unseen after buying someone else's toy-I suppose you can only hope that what you see is a true representation of the car and the way that it was put together. If issues do arise, you repair them as needed and this forum is a fantastic resource for information and advice towards that end. Thanks again to all who responded to this question and mine posted previously regarding my own vehicles.
