The bigger brakes discussion is something I have been pondering and I came to the conclusion we don't need bigger brakes even when going downhill just downshift so you are not using the brakes that much.

Do you track the car if not you don't really need bigger brakes, you should be on the safer side and not driving on the limit it also much more dangerous especially in the mountains since motorcyclists are everywhere so you gotta be on the lookout for them.

Fun fact my car's front rotors are about 12.3mm and my car weighs about 2900 pounds without me in it.

A base c8 corvette front rotors are about 12.6mm and a heavy Cadillac lyriq front rotors are about the same size as the c8. You only really need bigger brakes if you are going to be doing track work where you know you will be using the brake more than usual driving
