Drilled from the factory are no better. I can show you page after page of cracked factory Porsche drilled rotors.
At the end of the day, do whatever you want with you're money. I honestly don't care, I'm not trying to change your mind. I'm hoping that those getting into the car hobby read forums like this and make informed decisions on what they want to do with their cars.
And if you want the cool looks of drilled, awesome, just periodically check for cracks. There is definitely some benefit performance wise, especially in the wet. Just be aware of the drawbacks.
Because my car sees 4 or 5 track days and 10 to 12 autocrosses, I won't use drilled. They will 100% crack, guaranteed, because I've had it happen. I choose not to use slotted, because the car is a daily and I've used them before and had weird noise and high wear.
Good fluid, pads in the correct heat range for what you're using them for, proper cooling and good tires = good braking. Drilling and slotting help in the wet, but our cars won't really benefit, as they have pad drying via the abs system, where in the rain, the system applies just enough pressure to the pads to dry them via friction with the rotors.
Again, you spend your money anyway you'd like, I'm just providing the facts so others can make their choices.
