Increase torsional rigidity on 996 cabrio?

No amount of new suspension parts - stock, RoW, or aftermarket - will address OP's original question of how to "increase torsional rigidity on a 996 cab..."
As TheMystro pointed out, the coupe is going to be stiffer than the Cab - and a C4 coupe with the additional bracing for the FWD stuff is going to be the stiffest 996 you can get short of a GT3 or a car that's had a welded tubular cage installed.
OP, perhaps this is a reason to buy a second 996, so you have a rock-solid coupe AND a cab...

I'm not sure where you're at, but you can catch a ride in mine sometime if you around the LA/Long Beach (CA) area. My cab only has 20K miles and mechanic tells me it's a really tight chassis. I wouldn't know, it's my first Porsche and first cab...feels pretty flexy and creaky to me haha. Maybe it'll give you and idea of what it should feel like and see if that's good enough.

The only things I can think of to reinforce the chassis but not guaranteeing if it will actually help in a Cab would be the Elephant Racing X bar for the front and Brey and Krausse Harness bar to tie in the upper seatbelt mounting points for increased lateral stiffness. If you go over the top with the top tier version, you maybe able to dial out some torsional flex as well. Obviously with any of these items, you will lose some usability in that space.
