Because in theory, with two level sensors, couldn’t you use this to flatten the car through a corner? how fast the system responds al depends on volume and force required to move the weight of the object. Force can be changed by piston size and pressure to the piston. It depends on velocity in the hose as well, all these things can be tailored to make the system respond the way you want. In systems I’ve worked on with similar sized cylinders, full extension is 1-2 seconds, retraction is about the same. --- _[View the full topic](https://forums.speedlife.net/t/never-seen-this-done/102823)._
