Left foot braking is not a technique you'd do when you'd need to shift. (At least, not intentionally... I can certainly recall it happening by accident... biggest risk to using the technique as you can easily lose SECONDS off your lap time from a missed shift if you left foot brake going into a turn that you actually need to downshift on. )

It's a good technique for inducing oversteer (in a front-wheel drive car), and for reducing turbo lag (in a turbocharged car). Just not sure if anyone's found a place for it (under any circumstance) in a Boxster. It seems on a RWD car, left foot braking would induce understeer, which I don't know if it would ever be practically useful. It can make for somewhat quicker transitions between acceleration and braking. (It's awesome for taking a race-prepped FWD car very quickly and aggressively through a slalom! ). It seems the boxster with the dual-mass flywheel favors less aggressive, slower, more gentle inputs. I'd love to try driving a race-prepped boxster with a lightweight flywheel sometime.

It most certainly is, but only if the transmission can handle it. Obviously in dog-ring racing gearboxes clutchless shifting is the norm. In some classes it's done even with synchro's, like in SCCA Spec Racer Ford. Just don't expect the trans. to last 100k miles. LFB it's self doesn't affect balance any more or less than traditional Right Foot Braking. It's all in when and how you apply and release brake pressure. One large benefit is that you don't have to do the heel-toe dance , your left foot can concentrate solely on accurate brake pressure.

Ah, gotcha.

In spec boxster we will often LFB to move the weight forward in a fast, but not flat out corner, reducing understeer. Usually just a quick dab to get the car to turn in better. Can be tricky sometimes, as spec cars tend to snap oversteer. I wouldn't recommend trying it on the street.
