Double clutch is ignorant. Go look up ignorant.

Keep driving you'll eventually bind/bond, become one with your transmission/car.

There's more than one way to use the gearbox.
Proper technique is, well... proper technique and there's more than one.
"Not to start a war" and then you throw an insult? Man, I'm getting really sick of the egos on message boards. I never said double clutching was requisite, I personally do it for enjoyment and for the sake of learning a dying skill and I recommend it to anyone who is interested.

You say there's NO reason for double clutching? Have you ever had a munched synchro? Have you ever driven a car with a dog box tranny? Do you even know how a transmission works? Double clutching may not be necessary for our cars, even for downshifting, but downshifting is much harder on the synchros than an upshift. Why? The input and intermediate shaft naturally want to slow down, so performing an upshift simply assists the natural tendency to eventually match speeds. Using the synchro to speed up these shafts for a downshift however, requires more force and acceleration because you're opposing the natural friction present inside the box. It could be argued that vehicle speed is dropping as this is happening, which results in a smaller RPM difference between each gear, but I believe the forces are still higher.

Also, double clutching essentially eliminates wear on the synchros, much the same way a rev matched downshift virtually eliminates wear on the clutch.

I agree that double clutching is not necessary for a modern car. But to say there's NO reason, and to say performing the action is ignorant, really proves the point that the ignorance lies on the accuser. Go read the whole dictionary while you're at it.

Almost all cars get better gas mileage going down hill in gear than in neutral.

If you know your car, downshifting should be easy and rev-matching should be a part of that.

Why do the people who write the owner's manuals specify that you do as much engine braking as possible during the brake-in process? It must be super bad for engine/transmission...

No. On the contrary, during engine braking there's less wear, since the fuel is shut off and the engine is not making any power.

Engine braking keeps some compression forces on the rings and maintains a slight load to help gear surfaces wear a bit more evenly on both sides of the teeth.

I prefer downshifting since I can be in the proper gear to be prepared for bad situation or being in the correct gear if the light turns green. I'll usually downshift as low as 3rd and pop it in neutral when coming to a full stop.

push the clutch pedal and hit the brakes. doesn't matter what gear you are in and will not hurt the engine.

I like to just close my eyes when going from 60-0.

Downshift and rev match and you learn your car. Period. Coasting in in neutral is fine, when you are aware, if you are sure which gear to be in if needed. The dude coasting from 60-0 with clutch depressed, I am not sure I'd do that. I like to be in control of the car rather than have to make split second decision at the last moment to determine my fate. It is finesse and knowing where the power is at a proper rpm/speed.

I usually downshift/engine brake sequentially to 3rd...maybe 2nd sometimes, then use the brakes at about 20mph or so to slow down and when just about stopped push in the clutch and shift into 1st. When completely stopped I put it into neutral, release the clutch, and wait for the cross traffic light to turn yellow before clutching in, waiting 1 second, and putting transmission it into first gear... I have a 5 speed '98 Tacoma with over 160k miles on factory original clutch and transmission that has been driven like this 100%....and I've tracked it, taken performance driving schools with it, autocrossed it for 4 years, gone offroading at the landfill, and yanked bushes out of the front yards with it -slipping 2nd to get traction...

Best fuel mileage I've gotten with my FRS was driving though Arizona/Utah mountains and engine braking at 3-5k rpm levels....nearly 32mpg. Using neutral wastes fuel and wears brakes unnecessarily.

Yeah I noticed that,
I was being a hypocrite.
I apologize.

Should of worded it correctly.

No point in having OP learning double clutch on a trans that has no benefit of doing so.

I figure let em learn when its needed, on what its needed.↓

I wasn't calling you out.
If that was my intent you would of been quoted.

Double clutching on a trans that is intended to,
or bandaiding one is where it should be.
Or as you say it▼

Guess I just don't understand why people downshift when DD'ing. If I'm coming up to a light, and I'm in 5th/6th, I just put it into neutral and coast. Why not??

Just don't personally see a reason in wasting effort on double clutching and downshifting

Because you should always be rolling in gear unless stopped for emergency reasons, you are breaking Texas motor vehicle law coasting in neutral, and it's a sports car that likes to be played with not a boring DD econobox... that's why. Just coast down in 5th or 6th at low rpms and blip it into 3rd when needed for acceleration. Rev matching downshifts are easy to do...

I heel-toe downshift and use engine braking, depending how far away from my stopping point I use my brake pedal also.

Sometimes I even go into first gear and use that to engine brake.

I don't downshift only when I have breakfast while driving. LOL.

Amazing how many of you bought a fun little sports car and drive like old farts.

Coasting to a stop in neutral... Give me your man card and your keys.
