If you're racing on gravel, dirt, snow, or any other loose surface, you'll want to use left-foot braking to your advantage. It's a tricky technique to master, but it'll make you faster in virtually any car, including one with rear-wheel drive. Our pals up at in New Hampshire break down all the ways left-foot braking is useful in a rear-drive car.
Demonstrating the technique with a perfectly executed four-wheel drift, Team O'Neil's Wyatt Knox explains how left-foot braking allows you to both mitigate understeer and induce oversteer. It also lets you control the wheel speed at each end of the car, helping you keep the car sideways.
Left-foot braking also transfers weight to the front axle of the car, without totally taking it away from the rear. This means you have better front-end grip—thus, better turn-in—but you've still got traction at the back. Typically you wouldn't use these techniques on a road course—though some drivers do use left-foot braing—but on a rally stage, they're essential.
So, if you find yourself on an empty dirt road, or an unplowed parking lot, give this a try. With practice, you'll be ready to enter your first rally.
