Shifting before a turn.

[dkaparis]

Why cant you brake and shift at the same time? Why do you have to brake THEN shift?

Shift WHILE you are braking and you don't need the engine or transmission for anything anyway, then move foot from brake to gas with clutch still in, revmatch and accelerate out of the turn.

While the clutch is depressed, the engine is not there to force the driving wheels to spin, thus if you break at the same time, on a slippery road you can easily lock the wheels.
