No. the Firm Feel upper control arm only adds positive caster. The Hotchkis bracket changes the path of the upper control arm and subsequently the path of front axle in relation to the car as is moves up and down through its travel. The benefit is supposed to be reduced bumpsteer etc. The Hotchkis page goes into more detail.
Solid heim joints allow less deflection of the arm under load, but transmit more road noise/vibration. Rubber reduces transmitted road noise/vibration at the expense of increased deflection.
