07TouringZ is right, all the information is already laid out and we all have our opinions. Take what you will from the thread, however keep in mind that I've backed up everything I've said with sources.

There's a good chance that you will never experience a synchro problem in your time of ownership, but I like to play it safe and lower that risk from ever occurring by putting in the effort to double clutch my downshifts.

It is---Iv been building gear boxes for 25 years. Anyone with half an ear can hear their sychros doing their thing and down shift accordingly. If your on the track, jam the gears accordingly also---expect what anyone should if they are tracking.

Yawn >> at the Rocket Science concept of shifting gears, Jeez. If you cant feel in your butt when and how to shift after a couple months of Gear meshing, get an Automatic.

Random statistic? It's a FACT! You on the other hand is spewing so much BS and your a newb to this site you have yet to give anything useful.

Once you finish school let us know. You might actually learn something.

Spoolin Z....have you noticed that out of all of the posts in this thread, you are the only one that agrees with your opinion?
This should tell you something, don't you think?

Go ahead and double clutch your *** off. Just don't tell others it's the correct way to shift.

Double clutching is absloutely unneccessary on any modern fully synchronized tranny. And it will NOT extend the life of your tranny. It MIGHT impress your buddies down at the car-wash, but then again...maybe not.

And even though it is absolutely unneccessary, it will NOT do any harm. It will NOT accellerate clutch wear. So if you feel the need to impress yur buddies, (or yourself) just go right ahead and double clutch.

As I previously stated, double clutching in a modern car wth a fully synchronized is a silly old-time practice that is done by people who like to pretend that they are NOT driving a modern car with a fully synchronized tranny. (Some owners really like to believe that driving a manual tranny is a highly skilled procedure...but its not.)

And, BTW, I am old enough to remember when some cars did NOT have synchronized gearboxes.

All the information is out there now, so I'll leave it up to others to form their opinions. It looks like the majority disagrees with me, a small minority has no idea what double clutching actually is and another minority agrees with me.

Actually, if you read closely I agree with his oppinion as well. I dont think it's necessary to double clutch. I do think double clutching is better for your synchros...how much better? A tiny, tiny, very small, little bit. Is it worth it? probably not for 99.9 percent of people. But technically spoolin is correct.

I for one, have a completely irrational fantasy that someday someone will let me drive their priceless 1950's ferrari. It never hurts to practice.

How can you say releasing the clutch and letting it out twice does not accelerate clutch wear compared to doing it once? When it actually does. You have the engine spinning at certain speed. What do you think the clutch disk itself does when it touches the flywheel? It acts like sand paper to spin up to the speed and activate. It wears down a small portion of the disk each time you do this. Yes it DOES accelerate clutch wear, as well as throwout bearing, and pressure plate.


I agree with the rest.

I think the idea is that if the clutch and the flywheel are spinning at the same speed so when they touch there is much less friction and thus less wear.

If you downshift they are not spinning AT THE SAME SPEED. The engine will be turning faster than the clutch/transmission itself. It will still be double the wear.

Because the extra clutch cycle occurs in nuetral, and there is no load on the clutch. No load means no wear. It just disengges,a nd re-engages, but since there is no load, there is no slippage.

The only components that actually see any added wear is the clutch master cylinder and slave cylinder.

Okay, I will need to correct myself. I was thinking ahead of myself here. When you double clutch it actually never does it twice because its in neutral one of the times and the 2nd time it engages.
So it only wears onces.

Good info.

BUT double clutching doubles the wear and tear on your HIP JOINT! Dang. You guys (and girls) who are double clutching are risking premature hip disease. I mean is it worth it?
