When I was a kid, always heard terms of double de-clutch, heel and toe, no clutch gear shifting and so on from my dad, car magazines......At that time, all these sounded mysterious because you won't learn that from your driving school except the 1st if you learn lorry driving. If you ask someone who know the skills, they look at you like you are a fool. Asking dad, forget about it, how dare I! Every time he sits next to me, I got nerves and can't even perform normally
After owning my own car, i kind of started to practice the following 2 skills and basically use them in daily driving
Double declutch
Heel & toe
I know some say it is really 法國大餐 ， but as a diehard manual drive lover, I do want to master some old school skills.
Double de-clutch is easy, albeit heel and toe is a bit complex. But I would say the maneuver itself is not difficult, the following video explain it clearly
but paying attention to the Revs and adding proper amount of petrol is the trick, imo.
Lesson that I learn
Not all manual car is suitable to do that due to the arrangement of pedal
Brake too early. At the beginning, I almost braked the car to stop before my heel can really reach the accelerator or it becomes very choky because I had to push the brake pedal further down so that I could press the accelerator. One time, I had to brake harder, then thing became very smooth
Add not enough petrol (I still do )
What's your experience? Let's share.
Now, I'm practicing double-declutch + Heel & Toe when lowering gear, still not good though

Interesting thing, when the topic is "Heel and Toe", it is said "本帖包含不良信息，不能張貼。。。“ therefore I put in the chinese name. Why "heel and toe" is 不良信息？haha

Heel toe is way more than enough to smooth deceleration in these days. That's all I do now.
For beginners, I suggest not using the brake first, just focus on how much tapping to get rpm up to a desire range. Also by practicing like this, you probably not going over speed.
Then practicing just using brake and down shift, a bit shaky at first, (brake between 2000 to 3000 rpm, then down shift, no worry at all, you r not breaking your car).
After mastering both technics, then everything will be easy.
Btw, double declutch is hard... Good luck practing!
I get used to double de-clutch first, then tried Heel and Toe. At the ver ...
Ah Ching, I think double declutch is next level of heel toe, if I am not misunderstand.
Sorry, I need to zzZz, I will post more info later.
In the meantime, can other bros help me out here?
Ok, I think I know what is the difference between double declutch and heel toe.
1. Double declutch can be applied to both upshift and downshift. It does NOT involve braking.
2. Heel toe only applied to downshift, and does involve braking (of course)
Theory: both to minimize wear and tear
Double declutch must be used if a car has no synchronizer in gear box ( truck, race car, etc), otherwise you can't even upshift
How to apply:
Double declutch: release gas-> press clutch-> shift to neutral-> release clutch-> tap gas -> press clutch-> up/down shift.
Heel toe: release gas-> press brake (hold until finish)-> press clutch-> downshift-> tap gas-> release clutch.
My conclusion:
I never use double declutch because most cars are equipped synchronizer
I do not heel toe all the time, but it's extremely helpful when the road is slippery where you don't want to cause any change of motion.
I have tried to combine both, it's really difficult.
ng......I think they are different things for different purposes. But I can be wrong.
Double declutch is a must-have maneuver in the past because of the gear shape design. If the driver didn't do it, it is almost impossible to change gears, especially lowering gear. Otherwise, the gear box is prone to damage. Therefore, it is a basic skill in the past in order to drive, to smooth out the gear changing and to protect the gear box. Nowadays, majority of small cars drivers don't use/know the skill because of the popularity of the synchronization gear in small cars. But for lorries license test, it is still a mandatory test.
HT is to keep Rev during cornering so that max torque can be used for acceleration immediately after apex.
So in my mind,HT is an advance skill and I started from something "basic".

I must misunderstand double declutch before, I thought it refers to combine both "double declutch" and heel toe. Therefore, I thought this is advance skill.
Totally agree with the first part, new technology helped a lot. Think about the new manual gearbox introduced by Nissan which applied to Fairlady 370Z... It heel toe for you....
I've been practicing heel toe for a year. since I dare not to drive too fast, before I heel, the car usually come to almost full stop, need to practice more.

Cool~
What brand you are driving? I think Japanese car is easier to apply at first.
Are you practicing double declutch + heel toe altogether? I know it's really difficult. Good luck practicing!
To me, heel toe is enough for daily driving, actually even enough for track day event.
