Another BIG mistake with Cobras is barley stoppable brakes. Except for the 17" wheel crowd with giant rotors and big calipers, most of the 15" wheeled cars have brakes much too small for 600 HP cars.
For those that Open Track, you have seen the Vettes, Porshes, and other late model cars go past you just before you enter a corner. Not because they are faster than you are but because thay can drive in deeper and still slow down faster than you can.
For those that only cruise or do car shows 600 HP is 300 more than you need. You still have a better power to weight than most other cars.
And like others have said, Drivng schools,Driving schools.
