The Cobra may not be as difficult as it seems. The car's tendency to either spin or snap back the other direction at the end of a corner (assuming you've entered a power oversteer) is caused by the car's abnormally heavy wheels. As you throttle throughout the corner sideways, the rear wheels are spinning much faster than the car is moving, and the wheels' mass causes them to build up such momentum that letting off the throttle at the end of corner isn't enough to slow the rear wheels down enough to regain grip. To deal with that nasty problem, I give the handbrake a very brief tap (just enough to slow the rear wheels to traveling speed; this is fairly difficult to do well), let off the throttle, and watch as the chassis regains composure. Or, to avoid power oversteer altogether, I corner while depressing both the throttle and brakes simeltaneously. This method is much easier, but I like drifting too much^_^
