I was wondering the same.

I doubt you could adjust caster with those as they just slide in or out on the rod :)

If you slide the forward most rod outwards without moving the rearward one, you effectively move the top of the suspension rearwards, adding caster.

It would have its limits of course, but it could be used for fine tuning...

It doesn't look like you can move one without the other, that would bend the rods they are on.

The rods have to stay parallel and the bushings shouldn't allow for fore and aft movement.

With these. You can adjust both camber and caster.

how can you adjust caster??

Easy, all you have to do is to move one side of the arm. By the looks of that design. you should be able to move it about -or+ 2degs.

How can you move one side without moving the other if the rods are parallel?

The heim joints will allow for the difference.

If those are heim joints then
A. the whole control arm can move fore and aft
B. It still would not allow you to move one side without moving the other as the rods are still parallel and the assumtion is no bending.

If you look at the back on the pivot. You can see the heim joints. They thread into the sleeve that you think is a rod. The way it is adjusted. You loosen up the set srcews that hold the sleeve in place, turn the sleeve in or out. If you turn both sides the same. You adjust camber. Now if you turn one side more then the other side. You are adjusting caster. Simple, and easy to do. Nothing to it.

:iagree:

I understand now, sorry I wasn't grasping how one would affect the other.
So if you want more caster you would loosen the front sleeve and thread out the front heim joint which would move both heim joints in unison towards the back.

Basically, although I'd bet anything that changing caster will by default change your camber with these arms.

If you wanted more positive caster (+), and to keep camber the same. You would move the front sleeve out, and move the rear sleeve in.

Now if you wanted less caster (-), and to keep the camber the same. you would move the front sleeve in, and the rear sleeve out.

If you wanted more caster (+), and more camber (-). You might only have to move the rear sleeve in, and leave the front sleeve alone.

Clear as mud now. ;)
