Lew - You hit the nail dead on the head, with a wheel that is too light. Makes a car a bear to drive on the street. On a road race car the light wheel will make your car a bit faster IF, I repeat, IF your good enough driver. But it's for sure no fun. Sometimes a heavier setup will also make you a smoother driver in fast turns. Compression braking is not a huge factor on the lower compression engines that most of the street Cobras use, esp. big blocks.
