View Full Version : Making suspension parts for my 92 hatch.

Pulled most of the rear suspension parts last weekend and throughout the week at school in Chassis Fab @ WyoTech I made tubular items.
All tubing is 7/8" .156 wall... ends were tapped for 5/8" 18 thread bolts / heim joints. I then got 7/8" nuts and drilled the threads out and slid them onto the tubing and TIG welded them in place to be a place for a wrench to go to adjust the alignment. The heim joints are left hand threaded 5/8" and there is a 5/8" to 1/2" reducer pressed in so I can use the stock 1/2" diameter bolts.
The lock nuts have not been installed on the opposing end to the heim joints on the camber and traction/toe arms because I have yet to round the brackets. Once completed, parts will be probably be powdercoated a candy red or something similar.
Let me know what you guys think!!!

Lower arms were pulled yesterday and will be made this week at school. Today the parts seen above were taken to a local shop to be powdercoated Candy Red.

that's pretty awesome. those are really clean/nice welds. how long have you been welding? what did you coat the arms with?

Please get new bolts/nuts, or at least blast and recoat the OE ones.

looks good

clean them up a bit and you could start a business ;)

my only suggestion is to add the factory bend into the rear toe link

looks nice man, quality fab work as well.

Very nice. Quick question

where the thread comes from the bracket side of the toe rods- is that a bolt put through the bracket and welded in place? I know that would make the most sence, but i dont see the head of the bolt on the inside of the bracket... is it just the pic or did you actually weld threaded metal to the bracket?

also, is the metal DOM or is it Rolled? Also, is there a specific reason you used that exact metal/wall thickness. I'm pretty sure a lot of circle part arms are made from a thinner metal than that.

I'm not attacking/critisizing your work AT ALL. I just like hearing the thought process behind quality work.

very nice work, just make sure that everything is either adjustable, or set to the correct length, so you wont have any alignment issues

Very nice, I really like the idea of having the nut on the bars like that so you can do the adjustments easier. Clean welds too.

Why not buy standard type hardware for the RUCA's so you can adjust with the arm while it's bolted up rather than the eccentric bolt?

The end brackets is something I want to change before I start producing these. Currently it is just a grade 8 bolt with the head cut off and then a hole drilled into the 1 3/4" box tubing that I cut a side off of and then TIG welded on both sides. I'm not confortable with this setup as I'm afraid of the bolt breaking. I wanted to keep the head on it but it was in the way of the spindle where it attaches. Not only that, the measurement from side to side is incorrect so it would have to take .05" off both sides of the mounts to get them to slide over the mounts on the spindle to get the bolt through.

It is all 7/8" .156 wall DOM. The .156 wall steps the inside diameter down to the correct size to tap out for 5/8" heims... Thats the only reason. HOWEVER, when I actually start making these, I will be using

There is no way possible to set the arms to "correct length". All cars are different, and the orringinal equipment has ovaled holes for the use of the offset bolts for adjustment so there was play in the setup. When I made the jigs, I put standard bolts in the holes and centered them and then snugged the stand off plates up and then welded them into place.

Little update... The parts are sitting at PowderWorks in Mechanicsburg, Pa freshly powder coated with chrome base coat and candy red top coat...

Lookin good! I agree that the bolt body welded to the tubing looks a little ghetto compared to the rest of the work, but after I thought about it for a minute, I can't think of a better way to do it (if you don't have the head on there).

I like.

Coming along very nicely I see.

If you plan on lowering your car a lot, then be prepared to notch your subframe retainer for those toe rods.

Nice work.

Have someone track these (drag, drift, autocross, etc), test 'em on the street for awhile, and if they hold up, put them into production.

Just make sure you price them aggressively.

cool great job, keep us updated...how are the lower arms coming about?

Few issues arose with finding stock ball joints to press in. I've decided to do a machined style stud that slides in and bolts into a ball joint like those on Heim joints, like SPL Parts has their lowers...

I have other projects I have to finish 1st tho before I get any more progress on any of this.

If you plan on lowering your car a lot, then be prepared to notch your subframe retainer for those toe rods.

The lower rods will get a bend in them this next round so hopefully notching will not be required. I have a feeling there may be a few "prototypes" before I come to a final design of everything just because this is my 1st time doing this stuff.



Small update... I have a tubing bender and 1.75" die on the way along with a jig-a-joint on the way so I can soon start doing roll cages. After a few of those, I will order a smaller die which will be used for the suspension parts and after some more work, get a TIG welder and start on the suspension parts.

I'm still hesitant in everything as far as sales because of not knowing if I can get away with just doing Group Buys for now, or actually having to become a vendor on the forums.

They look really nice. What kind of rod ends are you using?

Kinda reminds me of Kazama parts, but not made with china $2 rod ends

Glad that you are doing custom work

But in terms of sales, I think it might not be worth your time

Specifically for suspension S chassis arms, there's SO MANY options already, from dirt cheap to stupid expensive, and everything in between

It's up to you, but its gonna be quite a challenge to break into the market and be competitive

This is just in regards to arms

I'd focus more on cage work and other custom fab work

The ends were bought at a speed shop for around $9 a piece. The guy put them in a QA1 box but I'm not sure if thats the brand or not. If I do a group buy run, I would be using ends ordered through QA1 but I have a lot of other work before I even get to that point... let alone having to get a TIG welder 1st.

ye sorry to burst your bubble making ANYTHING for S chassis to make money is useless
