I can't see one being very beneficial on our cars.
The entire reason for bracing anything is to keep a consistent contact-patch between the tire and the road.
Excessive Flex can allow camber-change, which can reduce the contact patch.
Unless you break out a tire pyrometer and find a problem that demands this sort of product to fix it, I wouldn't spend the money or deal w/ the hassles.

What would you hope to accomplish with one?
Establish that, then figure out if it accomplishes it.
If you want it for looks, there's no doubt that it looks like a Tie-Bar, so there you are.
If you want it for performance handling, try to establish what problem you're trying to eliminate, and how actively this would provide a solution.
