Brakes are outstanding on the track--nothing to be concerned about. If your second question has to do with fuel consumption on the track, I can't give you an exact number, but it is more fuel efficient than my 2009 GT 500 on the track. But then, I didn't buy either car for fuel economy. The car handles very well on the track and appears to be well balanced and stable at speed. Use your gear choices to keep the rpm's in the desirable range and it will pull hard exiting the corners. Good luck
