Can anyone give me some info on switching the location of my panhard bar from a long bar mounted on driver's side of frame to a short bar mounted on driver's side of the frame to the left of the pinion? Will this help in a dry slick situation? What are some of the handling characteristics that I will experience that will be different from the long bar set up? I am trying to get the car off the right rear and more on the left rear. Also, would a j-bar mounted over the pinion be a little better set up? I'm not sure if the short bar will be too violent since I've never seen anyone run one. Feedback good and bad would be appreciated.

IF YOU GO TO A SHORT BAR KEEP IT AROUND 18- 20 INCHES. SHORTER WILL BE TO ERRATIC,(REACTS TO QUICK) TWITCHING FEELING. WHEN YOU GO SHORTER, AND THE MOUNT IS MOVED FROM THE RIGHT SIDE OF AXLE CLOSER TO CENTER, IT HAS A TENDENCY TO LOAD BOTH TIRES INSTEAD OF RIGHT REAR. MORE AND MORE PEOPLE ARE DOING THIS, SEAMS TO HELP ON DRYSLICK TRACKS.

Trying to keep the short bar to 18-20 inches, would require that I use a J-bar and go over the pinion because there is only about 12 inches from the left frame rail to the pinion. From what you're telling me, that would be too short of a bar to use, so I should try and use a J-bar over the pinion. Any other thoughts on this topic would be appreciated.

will going to a shorter panhard bar be of any help to a pre '99 harris car and if so what kind of angles would you use and where would you place the rearend mount?

J BAR 18-20 INCHES IS FINE. START WITH MIDDLE HOLE ON PINIION BRACKET AND SET AT ABOUT 5-10 DEGREES DOWN HILL TO RIGHT. THEY WORK GOOD TOO, THE THEORY ABOUT J BARS IS WHEN MOUNTED IN FRONT COMPARED TO BAR BEHIND, IS WHEN AXLE ROTATES IT IS LIFTING THE J BAR AND SINCE J BAR IS CLOSER TO PINION IT IS LOADING BOTH TIRES MORE EVENLY. I HAVE ALWAYS MOUNTED A LONG ONE BEHIND BUT THE REALLY FAST GUYS IN MY AREA HAVE THE J BAR AND ON MY NEW CHASSIS THAT IS WHAT I AM GOING TO USE. SEEMS TO HELP MOST ON DRY SLICK, WHEN TACKY OR WET IT IS ABOUTY THE SAME.

A SHORT BAR ON PRE 99 HARRIS WILL WORK WELL. LOOK AT MISTER #3 OF HARRIS AUTO RACING. J BAR IN FRONT, ABOUT 18-20 INCHES LONG. START IN MIDDLE HOLE ON PINION BRACKET AND START WITH ABOUT 5 DEGREES OR SO DOWN HILL TO RIGHT . IF YOU CANNOT MOUNT TO THE BRACE BAR WITH A SLIDING CLAMP BECAUSE THE J BAR IS TOO LONG TO LINE UP WITH HOLE ON BRACKET, YOU NEED TO CUT THE BRACE BAR OUT AND INSTALL A NEW ONE WITH A CURVE IN IT TO MOVE IT MORE TO THE LEFT SO THE JBAR WILL FIT.

I could run the short bar behing the axle, but it would be a challenge to fab up bracket, and then it would have to be welded to the housing. Purchasing a pinion bracket and sliding chassis mount seems so much easier.

Chad,Put that J-bar back on for Chowchilla,,Yeah,I figured out who you are!If the short bar was behind the rear end,it would not give you that extra lift on the throttle.I been running one for 2 years now I'm happy with it.

I have ran a short J-bar on a DW7 with half leafs for a couple years now and i had good luck with about 12deg angle and mounted on the 3rd hole down on the pinion bracket. it seems to lower the roll center and help the side bite. i also run a rubber bisquit j-bar. although next year i am going to try full mono's with no j-bar for a change.
