First time i tried left foot braking, i locked up the fronts on my corrado and nearly went straight on at teh roundabout... thank god for a working ABS system. its alot easier now though with practice behind me, still not great at it though. Found my Corrado good at heel and Toe when was hammering it into a roundabout. Its pedals are perfectly situated. My passat tow car is easy to heel and toe. Quite funny to see people on guard at the gate on my base look strangly at me when they hear a car blipping down the RPM coming at them, shocks them to see a crappy looking green passat.
I found best way to learn heel and toe was using a Bradshaw tow motor all day at work. Only about 5mph and pretty gay but same pedal feel was the same as a normal car.
I pretty much heel and toe all the time now - sounds cool and is loads easier on your gearbox etc. Can't imagine driving quickly without now
