first of all, a Cobra is certainly not the right car to learn going fast in corners.
You steer more with the pedal than with the wheel.
Tires a very important, and BFG are really bad, Yokohama a little bit better and Avon the best bar Slicks. Goodyears are not radials, and they are difficult to balance. I had to throw them away after trying to balance them, which was impossible.
You should check you tire pressure, increasing it for cornering( I run 35psi in the rear), and you should have negative camber in your rear wheels ( I have 1º negative).
The list of things which affect roadholding is inmense, so these are the most obvious things to get right first.
Good tires, good shocks, good wheel alignement and the right tire pressure.
