Hi forum. I managed to get the rear upper/lower controls of today. That was a fest of sawsall, grinder, breaker bars, wd40, heat,etc!
Anyway….what bushings do you fellas use for the rear UPPER arms? (Competition susp.)

I cant seem to find the correct type.

I will use poly only if I have to….I prefer ‘normal’ rubber. Thanks

The competition control arm bushings for the upper arms are not reproduced and not available for replacement.  Most have replaced these arms with the standard arms as a result. 

For the rear, you can only get rubber for the lower arms.  Otherwise, the only complete set of lower and upper arms bushings are energy suspensions poly kits.  These kits only work with the standard upper arms, not the competition arms.  The poly are available in black, so they look like the original rubber, and they also greatly tighten up the rear suspension, more so than the competition arms your car has.

Shucks…….not available….crud! Can that really be true???  The upper rear bushings were shot, also the housings. 

Now what…?

Are poly available WITH housings?

I'd get a set of used of the standard (non-competition) upper arms and the black poly set.  Talk to CaliforniaJohnny, he might have a set of upper arms to sell you with the original bushings in place so you still have the shells as well.  Then just burn out the rubber.

Those would be the ultimate performance solution for sure, but you lose the original look.  They will help eliminate the 4-link bind and allow for adjustable pinion angle.  Top shelf stuff for sure.

Are there really no options for the competition arms?…😑
The hole in arm measures 1.524 in. Or 38.73mm…
There has to be some bushing out there that fits……..

There are urethane bushings available, but the suspension design makes those less desirable. The rubber allows some movement in off axis directions, the urethane creates a little binding. I think the Spohn arms are the best possible solution for mild or competition uses.

That’s how I did it when I rebuilt the arms…found it out by accident when the drill bit got caught but works sweet…

I have the bushings/housings removed already. They could not be saved. So, I cant use the poly….as the original housings have to reused
Anyway…..I have been doing A LOT of web-surfing for a possible replacement.
I have bought to slightly different 39mm(diameter) bushings……..I will post back if I can get them to fit nicely.

The original bushing center rod width is 60mm x 14mm(hole). New possible replacement is 55mm x 14mm…….we shall see…

Regarding the Spohn upper arms….by the time I have them in hand in Denmark, they will cost me upwards +500usd…ouch!

I am willing to try to experiment a little before such a huge outlay!

Correct me if I'm wrong but I believe the problem with the upper competition arm bushings is that they are spherical and not standard shape which is why there is a problem using regular bushings?  I know when I was trying to find replacements for my upper arms there was nothing I found that would work which is why I went with the Spohn set up. So far they are a great improvement and I am very happy with them.

Those are competition arms.  The regular arms have much bigger bushings and they are round rather than squared off like those.  Good luck trying to get a bushing to work.  If you do, you'll be the first.  Otherwise,  using poly with a set of used standard arms is likely a much cheaper solution than the spohn arms.  Keep in mind using all rubber on a 4-speed car will likely result in wheel hop.  Poly or Spohn arms seems to fix the wheel hop.

What do you mean by ‘squared of’? The holes look perfectly round to me…..what am I missing?

I am not talking about the bushing hole, I am talking about the arm itself. The standard arms are much more round, as if they are made from a round bar.

A possible solution perhaps!
I got  the 40mm Meyle bushing today. I was able to push it in solidly.
See picture……this initial test bushing seems to work fine. I will buy 4 more and do a complete install.
I think it may work. Thanks.
