A longer panhard rod means less angular change on the rod and so less side movement of the axle assembly.

To minimise sideways rod movement, one end of the rod must be just below horizontal at the rest position. The rod end should move an equal amount above horizontal at normal bump conditions. This means the rod end has the shortest side displacement for the amount of arc travelled.

pjz,
For the rod to tear the frame out of the car it must have been very short?


Quinn, I like your idea. Sounds pretty good to me. Any chance of a pic.

bah, i had side to side movement of my diff on my rally car, then i got real shockers and nolethane bushes and havent noticed any side to side movement ever

mick,
Could it be that you were not trying hard enough?

thanks for your replies guys,

This is what i have and what i propose to do....

1. Im currently running reversed eye leaf spring with extra leaf. (they are set just about flat).
2. Bump stops have been cut and shorterned up.
3. Koni adjustables.
4. Longer shackles on the rear to make each end of the leafs the same distance from the road surface I remember reading somewhere in a suspension tuning book that leaf springs will work better when they are parallel with the road surface.
5. 16mm sway bar.

now

what i propose to fit is a panhard rod to counter act the extra leverage, due to the longer spring shackles.
I have noticed some dents/marks on the chassis rail on the right rear made from the rear disc caliper, which suggest sideways movement of the rear axle. To add to the equation, i am also using slick tires, which produce extra grip.
The car in its current setup doesnt suffer from axle tramp.

Benny

i guess its circuit v. rally, cause im sliding the arse round anyway, and my road driving has a bit of a drift element to it too

benny, you have a rear swaybar, how was that setup?

have you thought about anti tramp bars? might stop some of the movement.
Im not sure about slicks. Ive hurd if you run them theres a totally different setup involved because of the extra strain on every part of the suspention.
