Just talked to them and it is an "adjustable swaybar" you can put different torsion sections in.
The remotely adjustable works as follows:
On the arm or cantilever portionas, the arm is a "thin blade" that can be rotated on a bearing. The blade has 2 thicknesses and therefore 2 stiffnesses, easywise and stiffwise. When you rotate the blade so that it is "vertical" you get the stiff setting. When you rotate it 90 deg, you get the soft setting.
I know for sure that they use these in Spring Cars and BMW Sedans.
This would be a wonderful product for Viper - especially with the problems of getting the car to turn in.
