My thoughts are that left-foot braking is a technique used to induce
oversteer, because by simulateously pressing on bothbrake+gas on a FWD,
the front wheels have forces cancelling each other out, while the rear
gets a drag from the brakes.  The result, according to "secrets of solo
racing" by henry watts, is supposedly oversteer on a fwd car.  You might
want to re-think your use of this technique if it's only adding to your
oversteer problem.

That said and done, I can say when I've had problems with excesive
oversteer in my VW Rabbit (FWD car like yours) usually making an
adjustment to the front/rear tire pressure distribution will hel,p a great
deal in making the car more neutral.

Kind of funny you mention excesssive oversteer as being a problem - I
thought I was the only one.  Most other FWD racers I talk to say they
can't get enough!  go figure...  I've been racing for only a year but I
know when the car is too tail happy (and my times will show it!)  Usually
it results in my taking the wrong line while struggling to barely miss
cones.
