You say you have swapped control arms and bushings etc - did you go with OEM style bushings or something else? The big bar I put on the buick did not add any hardness or harshness. All that said - can't hurt to remove the bar and see if the hardness gets better.
I replaced everything with a stock counterpart. Even the coil springs are the standard size/height springs, not the heavy duty variable rate springs; which it actually had in the rear. I am starting to wonder if the reason this car doesn't ride like it's on a cloud (like I remember these cars riding as a kid 30+ years ago) is because of the wider/heavier 15x8 wheels and 60 series tires vs the stock wheels and narrow tires? That's quite a bit more surface contact with the road. I'm running 255/60's up front and 275/60's on the back. The wheels that were on the car when I bought it were also 15x8"; which might explain why I did not notice a vast improvement or change in ride quality after putting the 15x8 rally wheels and entirely new suspension/steering parts on the car. If nothing was greatly worn out to begin with there wouldn't be a noticeable difference. I did have the notion to do as you suggested, and remove the front sway bar just to see if it made any difference at all. I just haven't had the time to mess with it this summer, let alone drive the car too many times due to all the rain we've been getting and the road work everywhere. The car only comes out on nice days and seems to sit in the garage more than ever lately.
