Hello everybody!

I just wanted some opinions on people with their method of downshifting.

I recently watched this video on a method of downshifting and it got me curious if there is a better way to do it. By better, I mean more efficient and giving the least stress on the engine and car as a whole.

This is the video I watched:

And his method was: Driving in 4th gear:

1. Lift foot off gas pedal
2. Left foot, press clutch down
3. Rev match (right foot) above previous gear and release
4. Move Shifter to 3rd gear
5. Release clutch (left foot)
6. Reapply gas to new
RPM range for gear
(Rev Match)


My current method and it may be a non efficient way, which is why I'm looking for more input on the subject, is to:
1. Downshift to 3rd gear
2. Let go of clutch slowly while trying to rev match

I usually get a slight bump most of the time because I think I might under rev it.


Any input would help, thanks guys

 

double clutch AND rev matching. less wear on your clutch.

 

It's OK. But doesn't really do what you need it to do. Namely get the car downshifted quickly when you're on the brakes. He also mentioned he doesn't do it into first.

You're better off learning to heel/toe (actually side to side) so you can downshift quickly when you're on the brakes. I double-clutch, but I'm not actually sure it makes any difference vs just rev matching, I just learned that way.

So the sequence goes:

1. Ball of foot on brake, outside of foot on gas.
2. On brakes, clutch in.
3. Out of 4th into N clutch out, blip gas, clutch in.
4. Out of N, into 3rd, clutch out.
5. Off brakes, on gas. Or repeat from 3-2 and 2-1.

The only difference in a regular 5mt on the 2-1 shift is that you have to rev it about twice as much because of the much larger gap between gears.

 

double clutch is different from rev matching, but if you do both its the best of both worlds lol.
and well just get double clutching down as a habit. rev matching is fun but sounds and feels stupid if you dont rev match it right.
and the way bushflyr said is a good way also. youll slow down hella fast. i only do that method on tight turns when going fast.

 

I've read that with our cars, double clutching isn't necessary. By our cars, I mean the GR's. instead we just need to rev match?

I've noticed that now I know approximately where the rpm's should be in certain gears so just rev matching has worked pretty good. Granted I'm not really racing anyone in real life... But in my head, well that's a whole different tread.

 

lol well even though if your racing or not it still cause the clutch not to wear as fast as opposed to letting the clutch slip against the flywheel to slow down the car. and well same as double clutching letting the input shaft free spin a lil less to match the rpm of the eng. less slipping but still causes some wear like normal downshifting. so yeah revv matching does work good.

 

I do the method of the guy on YouTube. I'd just stick with that. Leave the double clutching to Vin Diesel. These are Subarus not race cars. You gonna go around double clutching your moms Volvo station wagon?

 

and well to answer that part. drive alot slower and keep a loong *** distance between you and the car infront to allow you to slow down alot earlier so you can rev match at low rpms. 25-3500 rpms. and at the same time not using the brakes as much.

 

Double clutching seems like a waste of energy to me. Too much dancing. Just heel-toe if you have to.

Bottom line is if you drive your car, stuff will wear out no matter what..

 

in my experience double clutching is better off left to semi's and larger trucks. I just heel toe or rev match myself

just my opinion

120k hard miles on my original clutch. Maybe dancing helps?

 

my method is easy,

i have a automatic with paddles, so i just tap the left one to down shift

 

double clutching is for transmissions without synchros i.e. big rigs. waste of time for a synchro'd subaru transmission... rev matching saves synchros, motormounts, driveshafts

 

I rev match on a daily. I hit it a lot more in my wrx if I am going to 1st. If using to slow down its just a tiny rev match but if planning on rev matching into a corner and accelerating out I rev more.

 

everyones bashing on double clutching lol. it doesnt hurt a thing. even tho its a synchronized trans it still helps a little. just saying. and well not only subarus are synchronized, almost all automotive manual trans out there have synchros.
