This article, originally published October 10th, 2017, has been updated with an additional video from Team O'Neil demonstrating the importance of trail braking.
You've probably heard of trail braking, but do you actually know what it is or what it does? Trail braking involves easing off the brake pedal so as not to let the car understeer, while still slowing it enough to make a corner. It's a tough skill to master, which is why Wyatt Knox of is here to break it down for you.
When approaching a corner, it's common practice to give full braking in a straight line. Trail braking begins when turning into the corner while at the same time easing off the brakes, but still applying enough pressure to make sure you don't fly off the course. With the right pressure applied, the car will balance out, and you'll make it through the turn. Add too much or too little, and the car will begin to push.
The method is used by racing drivers everywhere to keep as much momentum as possible through corners, whether it be on asphalt, gravel, sand, or dirt. Watch for yourself as Knox demonstrates trail braking in a fully prepped WRX, then again in one of the school's Subaru student cars.
