Different things. The mass-dampers used in F1 weren't really part of the suspension. They were separate dampers, with a mass (weight) attached, tuned to damp out the undamped vibrations from the tyres, which move a huge amount on an F1 car.

It's an impressive piece of engineering, but probably unnecessary. The reason pitch is heavily controlled on an F1 car is because F1 aerodynamics are very sensitive to changes in pitch. That's where the active suspension of the early 90s came from, and the reason for the passive hydraulics (FRIC) used more recently.
On a platform with fairly neutral aero like a touring car, it's not necessary to control pitch like that. As far as I'm aware full-size cars like BTCC and WTCC just use 4 coil-over dampers and twin ARBs like we do.
