My car develops very serious lift resulting in lightweight steering at speeds over 70 mph. The front goes all light and the steering is almost non-existant. I have a Tornado Gt40 with standard suspension (350lb front springs , 500lb rear) correctly setup camber /toe-in Chassis is non-adjustable for front Castor. I am told this problem is common, as front air entering the nostrils creates lift under the nose. How can i best panel the chassis to stop this problem?
