I hear they're used in a lot of cars. Ernest, From past reports they compress to their maximum and stay there providing no protection against torsional vibrations. As best they just compress at worst they break and jump out of their retainers. So the reports go- but I'm no expert myself. Yep Their OK for cars, but best to talk to Tracy Crook or someone like that to get the engineers viewpoint. I'm not technical enough to give you the full gist, on the reasons why. BTW don't shoot the messenger! George (down under)
