My Missus has Arthritis in her spine and doesnt like a firm ride. If I set the ride height to normal, its a bit too firm for her, its not bad but we have just changed from a Lexus LS430 which went down the road like a boat. But if I set the ride to he middle setting, she likes it because its a bit softer and its higher for her to get in and ot of the car. If I run permenantly with the suspension on the middle setting, could it do any damage? I know it goes back down at a certain speed, but we dont often get up to these speeds (Not with her i the car anyway).
