Question global west A arm with aftermarket subframe

When I first purchased my 67 coupe, I envisioned upgrading the suspension to have a "G-Machine" as part of my total frame-off resto. I went ahead and purchased Global West A-arms, hotchkis springs, beefer roll bar, etc. Now, months later, I have the stock subframe off and I don't like the looks of it. It's been mashed in a couple places,etc. Is there an aftermarket subframe that I can buy that will be compatible with the geometry of the Global West A-arms?

Re: global west A arm with aftermarket subframe

No, but Global West may exchange them for rear suspension parts if you bought your arms directly from them. They have had people buy their drag race uppers on Ebay then want to exchange them for the handling package arms and expect not to pay the difference in price, but in your case it sounds reasonable to ask for an exchange.

I just saw the Art Morrison and Detroit Speed subs at a GoodGuys show, and both are top notch. You may be able to find a stock sub somewhere, Nova and Ventura up through 1974 used the same sub as a first gen Camaro. A second gen Camaro sub can work but needs some tweaking of the mounts.

Re: global west A arm with aftermarket subframe

I have his upper A arms and they look great.
I've met him at SEMA and he's run each part past an engineer to verify strength. The idea of using stock A arms or tubular aftermarket is pretty cool, a guy could upgrade to new sub with rack and pinion and use his current tubular A arms. There's no telling when it will be available, and I am allways concerned that torsional strength is part of the design goal. Some subs are not as good as stock in torsional rigidity. This is even more critical when you stiffen the suspension over stock levels.

Buy the June 2007 issue of HOT ROD. They have a feature on a whole bunch of first gen Subframes!

Of the ones I've seen in person, I like the Detroit Speed, and the Art Morrison.
I've heard good things about the 21'st Century sub too.

I think if you go with any of the Corvette aluminum spindle subs, you will need to use pretty large diameter wheels to clear the spindle and brakes. I don't know if you could use 17" wheels on them.

Re: global west A arm with aftermarket subframe

I emailed the people at Speed Tech Performance questioning when they expect to have this subframe available. Tim responded saying that they are targeting June 1st.

I'll be picking up that issue of Hot Rod when it hits the shelves.
