it's all about left foot braking and heal toeing the cluck with your left foot braking and clutching =P
i find in a miata a .3 sec heal toe gas peddle tap works well and most of the time just down shifting is all you need sense the car handles like glue most of the time. the only real reason to use the brakes is because your at red line and down shifting will put you at 8500rpms (atlest in my 6 speed) and thats not good. as for that left foot braking stuff only works for autos and sport shifters i would think.
also this is from run hallett can't run all tracks the same
