My friend is doing Formula Women this year and the first thing they learnt is to heel-toe down shift. Ive heard about this before and was intrigued now so gave it a go. Once you get the hang of it it works really well and you can instantly feel the difference. You end up with a much smoother and faster drive.

The sequence for a proper heel-toe downshift is as follows:
1.Apply the brake with the ball of your right foot.
2.Depress the clutch pedal with your left foot.
3.Place your hand on the gear lever.
4.Rotate your right foot counter-clockwise by pushing your heel away from you, then "blip" the throttle with the right edge of your right foot by rolling your foot down and to the right, while still applying even pressure to the brake pedal.
5.At the same as the throttle blip, move the gear selector into the lower gear.
6.Release the clutch pedal quickly.
Give it a go and tell me how you have got on. Its a very good skill to master and it will improve your driving too. Very useful for Track days!
