Ok, so I somewhat understand basic friction principles. I understand that surface area will not increase friction, that frictional force is the normal force multiplied by the coefficient of friction (no greek letters on my keyboard). This said, I can understand how bigger rotors and pads will only dissipate heat better, unless the force applied by the calipers is increased. I do not understand, however, where the advantage comes in from having wider tires on the car. Why do we say don't put 7" tires on the rear of a TT? It's only creating more surface area, but the normal force and the coefficient of friction have remained the same, thus friction should remain the same. So how do wider tires create an advantage in straight-line acceleration through traction? I know there's probably a simple explanation that I'm not thinking of, but I can't think at all right now.
Later,
