Default Steering doesn't straighten itself after turning

I recently overhauled the suspension on my '01 Aristo including Figs non-adjustable poly bushings in the lower control arms, caster arms, new inner/out tire rods, ball joints, RCAs, S9 adjustable front upper control arms. I'm also on coilovers with a very low ride height. My recent alignment shows toe and caster in spec, and camber at -5.5 degrees from the arms/drop.

When i'm driving around town or on the highway during a turn I can take my hands off the steering wheel and it will remain roughly in the same sport that I turned the wheel to, as opposed to correcting itself to it's natural straight orientation. I have to use about the same or slightly less effort to manual counter-steer it back to normal as I did on turn in.

Could this be because I basically replaced everything on the front end which is all brand new and need some time for break in? I wasn't driving the car for about 6 months while I installed everything, so I can't quite recall how it was before hand, but I'm sure it was different.
The steering and ride quality is very direct and great otherwise. I have the Figs poly steering rack bushings that i'm planning on installing soon that i'm hoping will help. Any other suggestions?

The alignment sheet is showing final caster as 7.1° which would be within the spec range of 7.1° min to 8.1° max

Thanks for your input. The steering feels very smooth throughout its range and doesn't seem to be binding. My only guess would be to try increasing the positive caster even more
