Due to changes in material thickness in the suspension mounting points between the ‘Vette and GTM, the suspension cam bolts run out of thread before they actually tighten down on the control arm….resulting in a very dangerous condition where you could suddenly have a severe change in alignment as you drive!  These Cam Bolt Washers are designed to remedy this dangerous situation.  They are designed to be plug welded to the existing cam bolt washer that is installed on the bolt.  Sold as a set of 6 washers so all your GTM cam bolts are covered!
