im not going to get into an argument with you online
i'll just agree to disagree
but you might wanna chat with a brake specialist to determine the whole purpose of drilling rotors. Yes certainly reduces weight no doubt. Definitely helps gases vent. Agree... but to say it aids in cooling i certainly dont agree.
in my two cars setup for the track they have different combination and types of rotors, pads and calipers.. and i assure you.. the temperature variance between two rotors of the same size.. one slotted and one drilled.. the temperature difference is literally negligible. I know so because i carefully monitor brake temperatures when i go on track because a big fat VW MKV R32 hammers your brakes and the unwelcomed brake fade is a constant reminder of its weight and heat management is a major issue in the R32 brakes
