Does it matter if 4 link bars are not mounted parallel to the frame rails? Or parallel to the opposite link on the other side of the car?

Not inline with the frame could be ok but not parallel with the links on the other side could cause a binding problem through the suspension movement.

Thanks, looks like I'm ok there, what about the upper and the lower on one side? Should they be parallel? I'm guessing not?

The angle of the bars is dependant on ALOT of things. There are several books by Steve Smith that explain it alot better than I could on here. Also the NEW GRT book by steve smith has the newest info in it.

To me it doesnt matter if they are not parallel to the frame or even to ea other. If you look most cars will have them toed in a little at the front. I have seen setup sheets that say to set them this way and if you asked the builders they likely woudl tell you the same thing. I have ours set so that they are toed in about 1" on both left and right sides., on a 4/4 setup.

Ego is right there is a lot more to it than just lining them up. Just an example if you look at a SKyrocket mod chassis his left rear bars are toed in about 2-3" at the front. His theory is that it moves the pickup point furthur under the car so that the the bar is taking more of the full weight of the car not just the left side.
