Custom control arm fabrication wanted

[grendel]

This is beyond my bending skill.

I need an upper adjustable control arm made to fit the rear suspension cradle and knuckle of a 2012 Camaro.

Background:

We put a 2012 Camaro SS (LS3) IRS into a 1973 Camaro. It's 64" WMS to WMS.

Detroit Speed makes all adjustable links which I bought, except for the upper rear. They said stock's strong enough and strength's the only reason they make them.

With the rear at 64" WMS to WMS, I'd like to bring it in 1-2" per side. The DSE links have that much movement in their adjusters. The body is 70" wheel house to wheel house and we want more dish in the wheels. I also think tube would be stronger, even if Detroit Speed Engineering says it's ok.

Who the heck can make me a left and a right?

It's the upper link that looks like a Gull Wing. just under the coil spring in the pic. Art Morris makes an IRS based on this, but they claim their links are entirely different and thus unusable. It's also not adjustable.

I can free up the factory ones, if someone wanted to use them to create a jig.

I would be worried that shortening the control arms 2" would affect the geometry and performance. Wouldn't you need shorter axles too.

I flared my trans am a little and like that route better. I actually just took all the measurements for my rear axle. My body is almost 74" wide now and because im running 8"bs corvette wheels i need 65" WMS to WMS.

What flares did you use? Wider's better for racing

I've had those thoughts as well. I want 1" a side. All the DSE arms I bought have at least that adjustment in them. Going from 64.1" to 63" would be grand.

If I need axles, it won't make me cry, as I can go with Vette hubs, match the front bolt pattern and have common hubs on all four corners.

That said, most of the suspension geeks I am talking with think we should just cut 2-4" out of the cradle, leaving all the suspension points where they are. It would also center the rear diff. The DSE stuff I have is more adjustable, stronger and lighter, which still works for me.

I would not mind flares and staying 64.1" with a 12" wide rim, 4" lip if I can swing it.

How about this?

chop the existing arm, modify the pocket to fit the upright, redrill the upper mounting hole and remount.
