I've done a search, but came up empty - maybe the wrong search criteria. Can anyone point me to a reasonably detailed diagram of a C4 frame? Doesn't necessarily have to have dimensions, but that would be a plus. I've been a C3 guy for a number of years, but the C4 is new to me and I have a project in mind. TIA

If your planning on using a C4 frame for another project I have bad new the C4 is sort of a hybrid unibody. I know these are not what you want....but its good for a bump





and here is a pic of the C4 ZR1 chassis


Here's the bird cage

Thank you for the replies. I'm interested in building something along these lines, but with one engine:

I currently own a '68 coupe, been a Chevy/GM guy forever and I'm trying to figure out a way to do something like this without having to do suspension mounting points, etc, from scratch. LS3/L92, Chevy/GM throughout. The thought occured to me the other night that a C4 front/rear suspension would be a great starting point.

Thanks for the diagrams and comments.

Buy one of those tube frames for a C3 that use all C4 suspension stuff and go from there.

Now that's one heck of an idea! Thank you.

Has anybody ever done anything to stiffen the frame of a stripped down car like Rodj's other then the typical bolt on's? I just started a project that I plan to tear down about that far and I keep thinking how it would be worth welding in some steel to stiffen the frame but I havent looked into if its been done and how yet.

Here's another shot

The only way you are going to get extra stiffness is by going the race car route with a full cage tying the front suspension through the main rollbar loop to the rear suspension.The main frame rail are a large section but there is nothing to prevent the front from twisting in different direction to the rear.Once you have a cage in there it becomes a stiffer 3D item.
