Only the very early 360s seemed to have problems with ABS/ASR if F430/Challenge Stradale size tires were fitted. Your 2003, like Steve said, should handle and brake great with MPSS in sizes 225/35 19 and 285/35 19. Paradoxically, ride may improve, too, because of the tires.
Just watch out for potholes, since they tend to bend F430 wheels because of the small amount of rubber between wheel and tire, especially in front.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
