A few of us (me and a couple of other toy car racers who now work for a rc design house and a f1 team), came up with the concept of active towers a good while ago. (2015 ish as I know I mounted the test parts on a TRF418). They can be effective.

This more recent article posted a few years ago explains the theory behind them.

Some of us have been still developing Rc suspension ideas and we have got something quite different we have been experimenting with which is very different indeed, but seems even more effective. but we want more testing yet. (If only real life wasn’t so busy).
