Hellcat power in a convertible

Is anyone Familiar with an A-body convertible Build with over 600 horsepower?

How does the frame hold up without the hardtop to stabilize? Only sub-frame connectors and RMS suspension..

The performance cars from the factory came with boxed in sections and extra supports, but these can be bought as kits and welded in.
Ever try to push a chain instead of dragging it?:D
