Cars that are not reinforced in critical areas will exhibit the "off center numbness" regardless of whose steering box is in the car. The bigger the front tires - the more numbness you will experience under load.
I got the FF Stage 2 box and their sector support kit and I definitely have a gap of about 15 degrees on the steering from center left or right before the wheels start to move. I wonder if it is worse because of my steamroller tires? I must say it still feels a lot better than my steering from before!
I have a reinforced K member in the Charger, a FF #3 box, 275-40-18 front tires and there is a degree of looseness from 11:00 to 1:00 no matter the adjustment on the top of the steering chuck. This is what I have heard elsewhere. I don't blame the Firm Feel guys. I think that it is due to the actual design of the steering unit itself. It is because of this that I am curious about the Borgeson unit.
