[stalle]

Hi !

I´m serching for a picture of a custom made upper a-arm made of
tubes with uniballs for the crossmember.
I think it was one of RallyBobs nice pictures, !

So please if anybody seen it, post a link....

The only picture I have of a custom upper arm on a Manta is here.
But some other members have posted pictures as well, mostly on GT's.

This winter I will be building custom upper and lower tubular arms for a Manta, but I have nothing but design sketches right now.

Thank you Bob !

It was not the picture I was thinking of, but its something
like that I will try to do this winter.
I will will copy some of the nice work that you have done
to the crossmember and suspension, if its fine for you

I have allso seen pics where you have mounted coilover
shocks USD. Have you planned to use coilover springs aswell ?

I have done some measurements on my sellholm coilovers
and I can't find any room for them in the front end....
(the diameter, not the length)

Yes, for this Manta with the tubular arms it will have coil-over dampers/springs. As well the rear suspension will have coil-overs.
The ones I am using are these

I wouldn't mind seeing a Rallybob sketch.

Heh, heh...they're not that pretty! Just enough info on the paper for me to not forget my ideas in my head.

Hi Bob !

How are things going with your coilover front end ?
It would be nice to see some pics of your work.

I have done some thinking of my own, and made some parts
for both upper and lower arms. I will try to make the upper
shock mounts as you showed on pics earlier. A question about
them, is there space to adjust the spring tension with the shock
in place or do you have to take it out ?

Here is some pictures of my attempt......
As you can see the angel of the upper arm is wrong, so now I
have bent them upwards. (no pics of that yet)

Please comment and give me improvements

One thing concerns me greatly. The upper ball joint has been turned 'sideways' on the upper a-arm. Many upper ball joints are designed to move in one direction only, otherwise they will bind and may bend or break. If you remove the rubber boot on the ball joint, you can see if there is 'slot' which the joint travels within, which guides the direction.

I have personally not worked on the tubular a-arm project for some time. Too many other things to work on right now.

As usual you are right again

I checked the balljoint today, and yes, there are a slot.
But with the travel I have in mind there would not be any trouble.
However I will try to turn the balljoint 90 degrees to be sure.
