Ride quality even worse than expected. Advice welcome.

When the car impacts a pot hole for instance a 1.14 T bar will deflect the lower
control arm less than say a 1.03 T bar under the same conditions. That shorter
deflection will transmit more of its force thru the chassis than the longer deflection
The bump stops hitting is another issue, chassis reinforcements make a big difference
in making a old unibody car feel more solid.
