You can still use them with different damper types, its just that they may not be as effective as with the Nitron dampers valved and sprung to their spec, and therefore the ARB adjustments may have a different effect. I was considering how well they would work with a set 111R suspension I've got - nice and compliant, but very controlled in roll and adjustable for front / rear stiffness.
I still fancy a set, but £750 is a OBD-T firmware upgrade..
