I work with Brembo techs and the misconception about big brakes is that they reduce stopping distances. Brembo does not even design their brakes to reduce stopping distances--they design them to disipate heat that prevents brake fade.
The larger the load--weight of vehicle, larger tires and wheels, etc., the more the heat generated and the more the stock brakes will fade.
I am not saying people should upgrade brakes just "because" but should upgrade if they work their vehicles hard and have reason to do so.
Race vehicles and rice rocket types who work their vehicles hard, need big brakes---H2's do not usually get used in a way to warrant big brakes. If I had big wheels and lived in a hilly or moutainous area, I would strongly conside them. Also, if I run at 90 Plus MPH on the highway and do a lot of stopping and braking, the same would apply.
