My feeling on the "lightness" a Cobra experiences at higher speeds, I believe has a lot to do with "stuck" air at speed.
I think more flutes in the top rear (if race car only) of the front guards to help air get out from under bonnet would help, Or raising the rear edge of bonnet a few inches to allow air to escape.
I say this after recently driving my car and the bonnet locks not being closed, all was fine until approx 180kph, then the rear of bonnet just gently lifted to allow the air an escape path.
So having a more permenant way for the air to get out, would possably help.

Just a thought.
