Done! Kenny Brown Subframes

Convertibles are already reinforced underneath the chassis (or within the chassis??) straight from Ford, due to the fact that of, well...they don't have a hard top tieing the hole car together. I don't believe the convertibles come with subframe connectors from the factory, but they do have additional strengthening in their chassis to make up for not having a solid roof. That's why convertibles weigh more than hard tops. That and the extra weight of the retracting top, electric motor, etc. So you might not be able to feel as big of a difference installing subframe connectors on a convertible as opposed to a hard top.

Getting subframe connectors welded in shouldn't be more than $50-$100 at most.
