Shocks and double sway?

I'm thinking Bilsteins if I renew the shocks. And the Helwig rear would be my go to. I agree with the possibility that I could create a fishtailing monster if too stiff but that's why I put this out there to hear from you folk.

I would be careful about putting bigger torsion bars on a convertible. They tend to be rattle boxes cause they have no roof structure.

The Bilstein's my actually take some harshness out of the car.

How thick is you current front sway bar?
