I was looking for a stiffer front sway bar that wouldn't potentially overburden the tires and settled on the SuperPro 22mm front sway bar.
There was no noticeable change in NVH but the car seems to have gained extra compliance over bumps and feels like it rides better than stock. I'm not sure if this is due to a different geometry with this bar or the use of poly bushings.
I also took some quick measurements (bathroom scale only good for 0.5lb increments).
Stock: 6lbs, 18.50mm (2017+ BRZ)
SuperPro: 8.5lbs, 22.19mm
I would've taken more photos but my endlinks put up a fight.
