Fabricating Control Arms

[Mommy Wagon]

Has anyone here fabricated their own upper and lower control arms?

I have a vehicle that I am looking fabricate a tubular front suspension, it is for weight savings, and performance gain. The issue is no one makes a tubular kit for a large C-body Mopar.

I was hoping that by posting here someone may have a suggestion to a manufacturer, or other ideas. The biggest problem I have is creating 4 jigs for each control arm that will only be used once.

It isn't all that difficult to build a jig and basically replicate the original A-arms. I can show you a jig my friend and I built about a decade ago for 1st gen F-body upper A-arms. If you're interested, please let me know and I'll take pictures of it. I'll be home after the weekend so a little patience is in order.

Besides that, did you already contact Marcus at SC&C? He sells very versatile upper "tubular" A-arm that may be adapted to fit your purpose. SC&C is a sponsor here so you can click their ad and there you go.

I have been thinking about the same thing for my 62 imperial so I can go with shockwaves up front.

I dunno... unless you have the right tools and computer programs to get the geometry right you will do more harm than good.
I would probably start off with some Circle Track components and work foreward from there.

BTW - I was mere moments away from buying a 65 Monaco 383 for my first car.

I am not to worried about building a jig, it's the cost for single use that I am looking at. I don't wish to make multiples, and I sure hope I would only have one set to make for myself.

My other thoughts were of using B/E body tubular arms and replacing the forward frame to make those arms work.

I will check out some of the manufacturers listed here, but it would seem there are a few options, replace the forward frame to work with other manufacturers parts, or custom build the arms.

Do a web search for 'locost sports car' or 'locost.' Check also LocostUSA.com and Locostbuilders.co.uk

The Locost was a Lotus 7 clone, a 50's/60's (and with Catherham into the current date) spaceframe sports racing/road car. Many builders construct their own upper and lower control arms, and many build sites have pictures of fixtures for single build cars.

they make pre made adjustable jigs for racing applications.
what i would do is bolt the stock arm up solid to uca mount, set at ride height and measure camber, caster.also check 2 inches of bump for camber to see gain, if you want more neg camber gain shorten the arm up slightly. if you only have 2 degrees casters, you know you can move the top of the spindle back, i would look to do 3-5º caster built in so you do not need to offset shim the control arm.
then dial camber gainin around .50 to .70 per inch
