One thing I can think of to do this is have this pneumatic system on a secondary regulator and use a servo to actively change the pressure of the secondary regulator. I'm not sure if this is legal but it'd be interesting for sure. You could adjust how springy your suspension would be. Another idea would be to use a center-closing solenoid and close the solenoid when the piston is wherever you want it to be.
