i thought you braked with the left foot in karts anyway, shifter or not
(i could be wrong, i have never driven a shifter kart).
the advantage of left foot braking is, as someone said, a more rapid (yet still smooth) transition from brake to throttle and vice versa.
like Jesse said, it won't turn a moderate driver into a great driver. before LFB will help you, you need to have your technique and line down first. it's one of those last 0.01 second things.
me, i don't left foot brake. i'm used to using the clutch with my left foot so my instinctual response is to put the pedal to the floor as quick as possible. the poor part throttle driveability and stalling tendacy of my car has taught me to left foot brake for street driving though, so i am not as quick to slam on the brakes anymore when i use my left foot...
