Looking to upgrade the sway nars but having difficulties finding anything specific for the tucson. Has anyone else had any luck finding something

I have not seen any upgraded RSB or FSB. You could look to see about upgrading the bushing if you wanted, that along often is a decent upgrade.

Shark Racing has a sub-frame brace...I used a similar setup on my VW to help eliminate body flex. I would expect that is a better upgrade than the RSB; I know if the GSW it was very nice improvement.

Just a thought. Many times, adding a frame mounted trailer hitch will stiffen up the body of a vehicle.
