Hello there
I happened upon this site whilst looking for someone to make me up a panhard rod and wondered whether anyone can recommend a company to me, preferably in the South/South-West.
I've recently fitted lowering springs to my vehicle (Daiahtsu Avanzato TRXXR4) and need a new rod making up, as the one on my vehicle is not adjustable.
Any help/recommendations would be greatly appreciated
Regards
Matt

What size are the ends and what is the rod made of. You could cut the present one and fit a spherical rod end to one end to give you some adjustment or you could use a left and right handed joint at each end so you can adjust it in situ. Most on here have made their own from cds tubing with either poly bushes or rod end bearings.

To be honest I'm not too hot on DIY engineering (in other words I haven't got a clue!) and would just like a reliable company to make me one up.
The main thing that's bugging me is how I would work out what length it needs to be, taking into account the 30mm or so it's been lowered. Is there a calculation I can use?
Regards

Idealy you should move the chassis mounting point 30mm upwards as well. This will ensure the panhard rod stays as near horizontal as possible under static conditions, and the sideways thrust on the axle as it moves up and down will be minimised. The panhard rod also stays the same length.

With the suspension lowered as it is, the panhard rod sits at an angle. This makes it impart a sideways motion to the axle as it moves up and down. That said, if the panhard rod is very long compared to the 30mm drop, and is close to horizontal there shouldn't be a problem.

You can calculate the new length required very simply using pythagorus theorum. Imagine the chassis mounting point and the old and new locations of the axle mounting point forming a triangle
