+1 for left foot braking.
Racing karts for ten years as a young boy it is all I know.
Stick gives some good reasons why its a good system.

In a kart its not the same as a car.
To drive a kart fast, the brake is a fast stab to set the rear end up for the corner.
!00% brake or 100% throttle, no grey area.
Karting is the best driver training you can do.

In a car you have gears, so the transition is slower.
I feel the same principals apply, apart from the gears.
I dont feel that its a great advantage to left foot brake in a car with gears/clutch.
Even though I do it.
Without a clutch, then left foot is a must. ( karts, F1)

If you have a turbo, do what you can to keep it on boost.
Stick likes to trail brake.
I like to brake hard and apply the throttle early to time max boost with the apex.
Whatever floats your boat.
