Fabricating Custom Knuckles with plate steel (Page 4/7)

It can be made to work as long as your lower coil over mount is a pivot, not a rigidly fixed end.

We probably should take this discussion over to your build thread in the CZ.

Yes .I would like to see more info about custom spindles .I have street dreams by ross drop spindles on the front of my car , but nothing is available for the rear .

This is what will be used to hold the upper arms to the stub on the spindle .This allows me to get rid of the strut and use normal coilovers in the rear of the car .Using coilovers instead of Fiero struts gives you a choice of hundreds of shocks .We have a choice of three at present , none of them adjustable .I have coilovers on my 91 civic wagon that have 36 damper positions .And the set for all 4 corners was less than 1000.00 .Now this design you see in the pic is just a variation of what people on the locostusa website have done for quite a while now .the difference is that they usually use a true upper A arm with a ball joint and a tie rod .A locost frame has tons of free space to be able to mount the inner tie rod pivot in the perfect spot . I made this mount to eliminate the tie rod because :1 It is next to impossible to find the magic inner mount point(it is not where GM put it) and 2 with an upper arm setup like this , you simply eliminate the tie rod .If somebody would make spindles that could accept upper arms , then a lot of work could be saved and geometry could be improved .But most of the member made spindles still use a strut and are 88 style trailing arm suspension .And I am not interested in either of those features .So here is the pic of my mount system , I have not added the coilover mount yet and it will get cleaned up with the grinder before I paint it .I won't post any more on this thread because I have led it astray and all this is all on my own thread anyways .But I will hopefully comment if someone comes up with something good .

wtfb, would you please post a link to your build site?

He has the ecotec build in the CZ.

Are you planning on having the upper arm be the sole link that keeps the wheel straight?

I have been looking at essentially running square tubing from the cradle that would bolt to the underside of the strut tower where the strut would bolt, and building an upper A arm off of that. Obviously the profile would be complex to keep it close to the lower frame rails, I may bolt it to there in addition.... I will scan a picture of my idea... hold on for edit

The plan is to eliminate the toe link and have the upper arm keep it all straight .So far I think it will work .If you go to my build thread you will see that it takes quite a bit of surgery and bracing to get a place to mount the arms .

Where did you source your bushings and outer sleeves?
wftb JAN 27, 01:55 PM
West coast fiero 84-87 front bushing replacement kit .They have to be machined to fit the tubes shown .They actually fit stock control arms .I do not know if these are still available or not.These arms are just a mockup and the outers are getting machined to fit proper tubing now .

I really need to drop by one of these days to check out what all you are building after all you are only a half hour or so away. Dan
