Wow, when I was playing with the suspension forty years ago all my choices were "these were for Daytona'" and "these were for Sebring" etc. I settled on what I liked but kept several rear sway-bars as I thought they made the biggest difference, and I even change them when I get new tires to match the new tires different handling characteristics.Same as what I am running In the rear (Bilsteins & 7 leaf). Front: 550 lb springs, Bilsteins, spreader bar. Inside: rollbar. Wheels: 17” TT2 with Nittos & upgraded larger brakes. I did each mod separately to feel the difference each change would make. The spreader bar which is the most inexpensive had the biggest single difference as it keeps the shock towers from flexing. Next will likely replace the original steering box with a new Borgeson unit.
