I like cars that handle well. One of the first mods I did after tires and wheels in 1988 were springs, sway bars and shocks.
After the BF Goodrich Comp T/A 255/50-16’s on all 4 corners mounted on 16” x 8.5” vette wheels with 1.5” billet aluminum spacer from Vette brakes and products I installed larger sway bars.
I went with Herb Adams 1 5/16” solid front bar with heim joint end links and urethane frame bushings along with his 1 1/2” solid rear bar (lower control arm mounted).
The icing on the cake was the ATR handling front springs, MOOG cargo coils in the rear and Bilstien shocks.
This setup had perfectly neutral steering, sliding through a turn while maintaining full control.

I feel the ATR rear bar would be a really good match for a factory front bar where all tires are the same size.
It would be a little big if the rear tires are larger.
You could save some weight by going to a 3/4” hollow frame mounted rear bar. It would be as effective and most are adjustable.
I just changed to a QA1 1 3/8” hollow front bar and a UMI 1” hollow rear bar (frame mounted) and should do the same job, have some adjustability and I lost 46lbs.
