| 5 expense and trouble while we others stand on the side lines and thank our lucky stars we got out while the quitting was good. Heaven knows what is going to happen before we are through. Probably the Corporation will look around for a scapegoat, find I made the original Dubonnet device, and fire me "pour encourager les autres", although I have been wringing my hands & telling Chevrolet to quit for over 12 months. The facts seem to be:- (a) You have to tune the frame up (to say 800 v/min) You cannot tune it down. (b) You cannot do this with those boxes out at the wheels. (c) Low speed wobble also becomes bad due to about doubling inertia around kingpin, (which however is sometimes nice at say 20mph on a dirt road). | ||
