Another vote for Firm Feel. I have the stage II and I am extremely happy. Their customer service was excellent.

I have the firm feel II and the front sway bar kit and the front tubular upper control arms on my 69 charger ,
I love the way it feels and steers to me. I don't want a big mopar to be to tight in the power steering,just tight enough to feel the road and have no old car wander or slop .
I like to be able to steer around parking lots and side streets with a two finger feel but that is my preference .
My vote is on the firm feel II .

I have a FFII on my car. I think my next step is to drop the line pressure with the shims as outlined above and see how I like that before taking the plunge for a FFIII box.

By the way I did see one poster on here talking about having a FF IV box some top secret super special box. Never asked them about it.

Anyone have a FF IV box how do you like it? Must be a prototype deal or maybe its a FF III run at 800 PSI?
