Drifting Technique:Heel Toe Shifting (Double Clutching)

Heel toe shifting is a race shifting technique that allows drivers to downshift quickly while applying the brakes. Proper heal toe shifting keeps the engine, transmission, and wheel speed matched up so there is no jolt through the driveline while downshifting. When drifting, heel toe downshifting allows drivers to downshift in order to increase engine rpm, while braking to transfer weight forward and off the rear wheels.



1. Before entering a turn, do your initial braking to transfer your vehicle’s weight forward. Double clutch / heel toe downshift (see next step). Turn your wheels into the corner. Carry enough momentum into the corner to induce oversteer.

2.
Clutch in, bring your vehicle into neutral, and release clutch. While on the brakes, slide your right heel over to the gas pedal and rev up (blip) the engine to match transmission and engine speed. Without matching revs on downshift, the engine speed will cause a jolt through the driveline, upsetting rear traction uncontrollably.

3. After matching revs, clutch in, and downshift your vehicle. Double clutching is optional, but reduces wear on your transmission. Use e-brake if momentum and downshift do not create enough oversteer.


4. Release the clutch, get off the brakes, and press the accelerator. Accelerate enough to keep tires spinning to continue oversteer. Add steering input (countersteering) to keep your vehicle from pivoting or spinning out.
