Whats the rule of thumb regarding panhard bars (J-Bar solid). I was told to take 10% of the total bar length, and that gave you your split from end to end. Example: 20 inch bar, 10% of is 2 inches. Thus frame side mounting position would be 2 inches higher than inside mount. Was also told that anytime I move outside position, to also move inside position the same amount as well. Is this true? Also what indicates a need to relocate panhard bar position as related to cars handling? And what is a good starting point? The car I'm running is a 1999 Rayburn with stock front clip, swingarm rear. My panhard bar mounts to right side of car.

Well, if your panhard is mounted on the right side of the chassis, this means that the bar is pulling the car down in the RR in the turns. I have also personally heard of this rule of thumb, but I usually throw it out, seems like sometimes in certain conditions that it doesn't apply. With the panhard mounted on the RR of the chassis and the left rear on the rear end, this means that if you go with more of an angle, that it will allow the car to move over the RR more. The Radius of the arm will allow it to move outward. This will set the car, but it looks to me like you would have to increase wedge tremendously to get it to bite correctly off the turn on a dry slick track.

My 2 cents.

We run 350 pounds bite. Track is dry/slick. So your suggesting a higher angle for right side mount to achieve effectiveness? Thanks for the help.

If your looking for help on entry, I would try that. It works completely opposite when your using that panhard setup. Loads at different points because of the change in radius. Should help on entry and setting the RR.

Whats Rayburns thinking on a right side mount anyways? I'm the only Rayburn at my track. There are several other swingarm cars there, but they all have left side mounts.

I dont know what Rayburn's thinking is, but I see the logic in what it is trying to accomplish, but I am not sure it is the best scenario to work with.
