This is an awesome idea but why would he bother with bolt on fiero hubs when now would be the time to change to something with a common bolt pattern. I would go to the intrepid hubs to get a bigger brake and a 5x 41/2 bolt pattern. On a build like this one seeing as you have to change one end you may as well change both. Of course I didn't read the entire thread and he may have had a set of wheels already.

Its a neat concept but poor execution. That tube running between the ball joints is carrying all of your load and stiffness and he cut 1/3 of it away to access the nuts. I'd have figured out a different way to attach the ball joints first.

I believe that is the Fiero drop spindle from Arraut Motorsports.

http://arrautmotorsports.com/suspension-information/ (scroll down)

Back in the nineties Rotus offered a big brake package. Custom spindles from Arraut with Wilwood calipers and mustang discs.

I was not impressed.

Andrew is correct about the weak spot. An encounter with a curb bent mine right at the cutout.
The now scrap custom $$ spindle was replaced by the original Toyota Corona upright that is still on the car.

Solid center tube with tapped ends, a big arse bolt use to hold in the heim joints.

Some people want to use ball joints, heim joints are not a good long term solution.

I have done similar to above for ball joints, might have a picture somewhere.

Here is another "shop built" spindle. Looks to be stronger where the ball joints attach.

Perhaps a marriage of the two?

Don't know how strong it is but it sure is a clean design!

loading the bottom heim joint like that is not my cup of tea (especially if there is no safety washer )

but the use of a oversized heim on the upright to get KPI without lots of material/machining is kinda cool

... however, bolting a second heim to it looks a little goofy

This. What's to stop that upper dual rod end "assembly" from freely rocking from side to side? It "seems" like if you grabbed hold of that upright, that double upper pivot would move all over the place. Is one of them actually rigid?

Considering the source, "Brunton Auto", I would expect the piece attached to the upright to be Solid. Summit sells them!
The heim on the end of the UCA is high Misalign.
Don't like the heim on the bottom, but a spherical bearing should work ( with a safety washer).
The videos ( see above link) shows similar uprights used in back.

sorry... i wanted to say using a rod-end and not heim ,
but still ; what is keeping the rod-end from rotating in the upright under impact ?!?
is there a hidden keyway ? is the r-e welded to the upright ?
i hope its not only the torque of the nut

talking about impact; (upper BJ removed from one of my sandrails after a bad driving error in the desert )



whats wrong with using good old "ball joints" ?!?
i always liked them as a easy to replace "fuse" to absorb energy (and take the damage instead of the frame mounts or control arms)

anyway, as this pic shows the forces on the spindle "mounting points" can be HUGE
... i dont think i would use a bolt on rod-end that could rotate there.

however, if the rod-end would be a high mis heim (and the UCA would have a double shear U-fork tab welded to it)
and the LCA would have a BJ instead of the heim
then i would call it a interesting solution.

just my opinion

right after i posted this ^^^ the gears in my head started crunching ...

maybe flipping things around IS a interesting solution for my aluminum spindle problem

what do you guy`s think about this design ??? :





lightweight Nissan Altima Unit-bearing
1.5" thick 6061 T6 main body (with .125" steel "DL narrow" caliper bracket)
~ 9.5 ball spread, ~11 degree KPI, 4.75" steering arm length, ackerman looks fine,
scrub is a little close to center contact patch for manual steering (but it will be a light BEC car)
Moog BJ , chromo Heim`s (with high mis spacers) for upper and "steering arm"
UCA and tierod with double shear U-tab welded to tubing

toe adjustments would require unbolting of the tierod
... but i could live with that (its not something you change very often anyway)

any suggestions and comments very welcome

Actually if you replaced the tie end with a clevis then an adjustment rod would allow infinite toe settings. As for the upper adjustment point a bolt on point going straight up would allow an A arm style upper or 2 links coming to that attachment point with a spherical joint attaching them. Quite simple and elegant, never mind the fact that they have been done this way for years.
