Hey Otto, I was actually thinking the same thing yesterday! But in regards to the rear suspension.
A little brain storming:
I was thinking I would either zip tie the coro to the lower bar, or use a bracket and attach it with U bolts like Mcrews did.
You might be able to find a place to bolt a bracket onto the lower control arm.
Don't know what you drive, but the RAV has a couple of access holes in the lower control arm. Something like those might make good attaching points? Might be able to get something inside the arm that can be screw into via the access?
Other issue, which might prove to be way bigger, is the actual movement of the coro. Not only will it pull on screws or whatever securing method you're using. But I would think there's a good chance it would/could move more then a whole sheet of coro will allow? I have a couple of ideas for allowed movement, but it would be hard for me to describe it. Some kind of layer design.
