Need a How-To: Building Control Arms

[GaRys69]

Yeah for me also, some are lucky enough to have their company pay for it.

Pick a cross shaft, pick a ball joint, pick tube size and build a jig. (not my pics) These are from a C6 based GTM build. First is rear arm, last two are front. Hope this helps. Here is the photobucket I stole these pics from http://s926.photobucket.com/user/jch...?sort=6&page=1

Starts at page 114. This can probably get you where you need to be. Ive hobbled kits together for odd cars a few times with these.

That catalog is a great go-to for parts! However, it did spawn another question.

Is there any benefit/problems with longer vs shorter control arm shafts?

[mitch_04]

Anyone have an answer for me? Please?

I would assume that the wider control arm shaft would be better for arms with more clearance for things like shocks, coils, or bags. Maybe stronger against torsion "wrapping" when the brakes are applied? Smaller arms for tighter situations...

Any of these assumptions correct or does someone have some information that would help?

You are correct, no geometry advantage to having a wider cross shaft, only for packaging purposes. The pivot locations will be on the same plane, regardless of their distance apart
