Hi all, Thought I'd ask y'all which side of the frame to mount the panhard in my metric street stock. I run on a semi-banked 1/4 mile dirt that goes dry slick by the main. New rules will allow us to run a panhard and not alot of locals are sharing set-up info. Thanks for the help! Race

Attach the chassis end to the left side of the car and attach the differential side on a pinion mount. Thats if you are running a straight "shorty" bar or J-bar. If you are running the long panhard bar behind the diff. then the right side attachment will not be on a pinion bracket. It will be mounted on the backside of the differential.

Hope that helps.

Ok Fly, this is what I got. My panhard bar is around 32" long. I was thinking of putting the chassis mount(tube type) on the drivers side behind the wheel and the rearend mount about where the pass. side rear spring is mounted (stock position). What do you think? Race

that would work, but let me tell you what it will do.

First that will move the rear roll center to the left extremely! That can be good, it just depends. It will make the car roll over more. BUT it will not load the rear tires equally. It will load the LR more, due to its attachment point on the diff. being so far to the left.(I am going off the thought that you have a metric car with factory rear spring placement) Moving the diff attachment closer or as close as possible to the center of the diff. will help to load the tires equally. This is what you are shooting for anyways. Some people adjust their whole cars off the LR, meaning that they are conserned only with the LR bite and such. If anyone does that and has success good for them. But I try to work towards a balanced setup, it will be faster through the WHOLE race, the tires will run cooler therefore providing more available traction and tire life.

Everything on a race car is a compromise to something else. You've got to find the CENTER point of you and your cars behavior!

So I recommend that you mount the diff side of the bar as close as possible to the pinion shaft. If you are running the factory diff. I'm not sure if they make a pinion plate for it, but I'm sure you could invent something for your own needs. Because everyone knows that race car drivers are some of the BEST inventors!

I hope that helps you, if you have any other questions, please ask. Also if anyone else has a different opinion on this please feel free to add it. Thats why we are here, to help one another.

Modifieds run all different kinds of panhard bars. The bar should be mounted to the chassis on the drivers side and on the rearend wherever you want. It's all drivers preference. Whichever tire the bar is mounted closest to on the rearend will be loaded more. If you want to plant that right rear, then run it out to the spring. I personally believe it's best to mount it as close to the center of the rearend as possible so it loads both tires.

The lower overal height of the bar will create more roll and more side bite. More angle will create more side bite. And the shorter the bar, the quicker the reaction you get. The best thing to do is make several mounts and just try and see what you like best.

Thanks everyone. I'll try and build some type of mounting to go in the middle of the rear housing (backside). I've got some oddball 9in that the axle tubes are 3 1/4 or larger anyway. Racer, I plan on taking of the left upper arm to avoid bind. Thanks Race
