I could not have said this any better except to add that if you go buy all this mondo brake stuff and can't lock the fronts, you're wasting your time. If you can't lock the front brakes, you're leaving stopping ability on the table.
For stability under braking, the fronts should lock a little before the rears. Once the tires are skidding adhesion is lost and you have less ability to stop.
The opposite effect is acceleration as in drag racing. If you break traction and smoke the tires, the other car wins.
Proper brake setup is a delicate balance to not quite allow the rear brakes to lock when the fronts lock. This affords the driver notice to ease off the brakes very slightly to get the fronts rolling and maintain the ability to steer. Better to drive around something or hit where damage is minimized.
