How much should you lengthen the panhard bar when you lower it on the housing or raise in on the frame? Enough to locate the rear end in the same spot? Or do most guys just leave it the same length and just make the adjustment? Thanks!

hi. we ran the long bar behind on a clamp bracket so when we change heights we just slid the mount sideways to center the rear end. we had a jig that clamped to the frame and went over to the torque arm mount to make sure we were close when we adjusted. this year we are switching to swing arms with a j-bar, i dont think we will mess much with angle at the track, just up or down on both ends. we may also try the short bar but do the same thing so it won't pull the rear end sideways. john

you gonna come down and visit us at alexandria now that we are going wissota???
how did you like that dry slick pig of a track??? not usually that dusty though!!!

Love em when they are black and shiny! Can't get anything nice like that at home. I've been just dropping the bar for 2 years now, Jay (from Specialty Fab) says that is fine, but with the 4bar/zlink, we are getting tight in the middle. Hope to see you soon at Alex and Madison.

on my own design of chassis, we have made the frame mounting slider bracket on the chassis at the same angle as the panhard bar arc travel.........that way as you slide the bar up and down, the rearend stays exactly in the same place.

What a great idea! That would sure make the adjustment quicker at the track.

You are right on ford...thats how a car should be built.....the radius and angle of the mount should match the bar that you are using. It is pretty hard to get exactly on....especially when you tighten or loosen the heims, it will change the length of the bar, but if you work to get it as close as possible..it will help alot in making adjustments....a lot of people do not realize that.....
Same with trailing arms....start changing the lengths of the bars and the brackets need to be changed as well...otherwise you think you are making an adjustment only in angle, where you may be pushing or pulling the rearend back or forward on one side actually inducing lead or otherwise in the car.....this may help or hurt or may counter what you intended to do in the first place.....very important.

thank you, jammin, and i also have my front pullbar slider bracket mounted the same way, as not to gain, or lose pinion angle when the angle of pullbar is changed.
