Some drivers show up to track days with fancy automated gearboxes that contain more than one clutch. Those transmissions are brilliant pieces of engineering that resolve many problems associated with shifting gears in a high-performance environment. However, many of us opt to use cars with manual transmissions on track, simply because we love driving them. Operating a manual transmission efficiently on track takes work, and most drivers have to practice before they perfect the art of shifting quickly and smoothly, both up and down the gearbox.

At my first racing school, I knew the learning curve was going to be steep, and I was overwhelmed with the entire process. From basic corner theory to racing in the rain, it was a lot of information to process, but my biggest challenge was learning how to heel-and-toe downshift.

In short, effective downshifts are essential to quick lap times. As high performance drivers, we use brakes to slow the car quickly, not a sloppy downshift and engine braking. Plus, brakes are cheaper to replace than a clutch, a transmission, or an engine. Perfecting a smooth and effective downshift technique takes a significant amount of practice and while we can practice this on the road, I truly understood the importance of a buttery smooth downshift when I started racing because I was forced to learn on the fly. I figured, get up to speed, son, or other sports beckon.

If you’re at the point in your driver development path where you need to clean up your shifting, this article is for you. Without getting too esoteric about an overall approach to a quick lap or simple corner theory, we’re focusing on shifting techniques here.

On the surface, a heel-and-toe downshift appears to be a shifting technique, but especially on track, it’s first and foremost a braking technique. When properly executed, it ensures you’ve braked perfectly for the corner you’re approaching, you’ve shifted smoothly to a lower gear, which will optimize your acceleration out of the corner, all while maintaining the balance of your car during braking and downshifting.

For our purposes, I’m going to assume that you’ll be seated properly in your car so that your limbs aren’t extended in order to reach the wheel and pedals. As well, your pedals and choice of footwear should be optimized to reach between the brake to the throttle pedals. In most road cars, I wear skateboard or BMX shoes, which tend to be wider than a typical athletic or racing shoes. In all of my production-based race cars, though, I use large racing-grade pedal covers that provide better grip and minimize the space between the brake and throttle pedals.


The Steps

A perfectly executed heel-and-toe downshift happens so quickly that it’s difficult to comprehend by simple observation, but it can be broken down into six discrete steps:

  1. Begin braking.
  2. Push the clutch in.
  3. Downshift
  4. Blip the throttle.
  5. Release the clutch.
  6. Release the brake.

1. As we’re approaching a corner, start braking at your chosen braking point and because you’re slowing for a corner, you’re going to be using some meaningful brake pedal pressure and you’ll maintain that pedal pressure throughout the braking zone. You’ll need to place your right foot on the right side of the brake pedal, ideally with the ball of your foot securely on the brake pedal.

2/3. While you’re braking, the next step is to push the clutch in, followed by shifting to the next lower gear. These two movements are easy enough, but most drivers find the timing of the next two steps challenging.

4. As you’re braking and maintaining brake pedal pressure to slow the car, the next step is to blip the throttle with the right side of your right foot. In some cars, quick flick of your ankle and in others, it may take what seems to be an unnatural movement to hit the throttle pedal with the right side of your foot.

5. What you’ve done is caused engine speed to increase while the transmission is in neutral and we need the engine to reach higher revs because we’re shifting to a lower gear. The objective is to release the clutch perfectly in time with engine speed dropping so that you avoid any engine compression braking, which will upset the balance of your car while approaching a corner.

6. Finally, you want to smoothly release the brake pedal and avoid jumping off that pedal quickly, as that will also upset your car’s balance at the most critical part of the corner – the point at which you transition your right foot back onto the throttle.

Parked Practice

If you’re new to heel-and-toe or your technique can use some refinement, there’s a simple exercise you can use to improve your on track performance. In the paddock while parked, you can practice that movement of maintaining brake pedal pressure and blipping the throttle at the same time. Sure, you might annoy your neighbors in the paddock, but it’s a racetrack and it’s going to be noisy.

With the engine running, the transmission in neutral, and your car secured from rolling (e-brake or blocks), apply brake pedal pressure just as you would while approaching a corner on track. Focus on rolling your ankle so that you can easily and quickly jab the throttle pedal with the right side of your foot.

Keep an eye on your tachometer because your objective is to consistently see a 2,000 rpm increase in engine revs. (Ex. If your engine idles at 1,000 rpm, shoot for a jab of the throttle pedal that pushes engine speed up to 3,000 rpm.) Practice makes perfect and you want to create that muscle memory for that specific ankle movement. Once you’re able to consistently produce that 2,000 rpm jump in revs with that ankle movement, take it out onto the track.

On Track Upshifts

Although downshifting on track is a serious challenge, that doesn’t mean we can ignore upshifts. When it comes to minimizing lap times and maximizing the lifetime of your equipment, there are a few considerations.

As always, smoothness is key in terms of both shift and clutch action. Just like a well executed heel-and-toe downshift with perfectly matched engine revs and clutch release, upshifts should be smooth and never rushed. Take your time while upshifting to get a feel for your transmission before rushing gear changes. (Sure, we all have that friend who loves to perform speed shifts in their pony car, but that’s won’t help post better lap times nor will it extend the life of the car’s driveline.) With more seat time and mechanical sympathy, you’ll naturally shorten the time it takes to complete upshifts.

Timing of your upshifts is also critical because—believe it or not—most production cars will achieve maximum acceleration when shifting below redline. Instead of using your car’s redline as the shift point, first take the time to understand your car’s power and torque cures in graphical form (the internet is great for this sort of research) so that you can determine more suitable shift points.

Essentially, with each upshift, you want time each upshift so that engine revs settle after the gear change at a meaty part of the torque curve. As you release the clutch and get back into the throttle, engine speed should be at the point the motor is producing maximum torque, which naturally results in the quickest acceleration down the straight. The engineering-minded among us can go a little deeper and use gear charts for technical precision, but sometimes a good feel for the car’s torque curve can go a long way.

Before your next track day or club race, you should always prepare a plan with two or three objectives to improve your performance. If you’re at the stage where you need to work on your upshifts and your downshifting techniques, take these tips and tricks with you so that you can put them to good use.

Don’t be discouraged if perfect downshifts don’t come naturally at first. As with everything, practice makes perfect and in no time at all, you’ll be shifting like Mario Andretti.
