Awesome technology! "Yes, the electronics in this car are specifically intended as performance parts, not safety features. Switch them off and you will not be able to lap a circuit as fast as you can with them on, not even if your name is Fernando Alonso. You might just be able to match the system for a couple of corners if you fluke the perfect sequence of brake, turn-in, balance power, apply throttle at the exit. But over an entire lap, no; the electronics will win every time. This is not the case with any of the companys production cars, all of which are quicker with their TC and stability systems switched off."
599 owners may be interested to know that the gearbox hardware is the same as the 599GTB. the software has been updated for quicker downshifts and also to downshift to the correct gear so it will downshift from 6th to 2nd if need be.
