think about this. even if you're not an aggressive driver, and maintain speed limits, when ANY other car on the road can stop much quicker, and in a shorter distance than you can....that means you'll end up in their bumper. even driving down the road at 35mph, if the car in front suddenly slams on the brakes, it's going to stop before you.
sure drums stop fine.... as long as everyone around you has them too.
what if a child, or a deer, or other animal ran in front of your car.
even at 25mph, drums vs disc could mean saving a life.
