Double clutching became popular long ago when cars didn't have synchronized transmissions. With the newer transmissions, completely unnecessary IMO.

Its unnecessary until you have to rebuild your tranny with new synchros and gears. I didn't understand until I helped a friend rebuild his tranny. Granted it was at 102k miles on a 93 vr4 but the synchros were severely worn and 2nd gear was trashed (it started to grind then blocked him out entirely).

Don't actually try using your heel... use the right side of your foot.

Ok. It could have been caused from abuse other than double clutching tho.
Also, as you said, it was a '93 with over a 100K on the tranny.

Excellent point.
I don't think spoolins NSX analogy proves or disproves anything at all.

I used to double clutch for a long time. But since I no longer drive big rigs, there is no need for me to. And no need for you to as well.

Double clutching to save the syncros from normal wear and tear is no different that recommending someone not to drive in order to save tires. It's what they are built for.

BTW, the mere fact that your tranny has a syncro means it will get used, double clutching or not.

Default Double Clutching

I'd like to be kind, but it is hard when I know there are inexperienced drivers out there that read this thread and walk away needlessly confused. Think! If double-clutching was important or had any value in a properly operating vehicle today, wouldn't it be in the owner's manual? Wouldn't it be done by the experienced drivers?

Or maybe I should have double-clutched my '93 Pathfinder over the last 320,000 miles. I bought it new, I downshift ALL the time clear to second, it has the ORIGINAL clutch and the sychros are fine. The last time I double-clutched anything was a farm tractor and I'm older than some of your parents. Agreed, having a clutch last that long(it's weak now) is phenomenal, especially because I am a bit more agressive driver than most.

This stuff about double-clutching, except to impress someone or operate a vehicle with problems, is bull caca. Don't teach others to act like idiots.

Any comments?

oh

I have driven vehicles that needed to be double clutched. A properly working 350Z does not need to be double clutched. I would not recommend the average driver double clutch a properly working 350z.

Umm your a idiot. The way he does it now is the proper way to shift especially on a track. It puts actually less wear on the clutch and syncros.

Both you and your friend will wear your syncros by rev matching that way. In order to properly rev match a downshift to put no wear on your syncros you should:

1. Press in the clutch
2. Select neutral
3. Release the clutch
4. Blip the throttle
5. Press in the clutch
6. Select the gear
7. Release the clutch

You can do this within a fraction of a second with some practice. I taught my girlfriend to do this over a year ago and its made her downshifting much smoother.

Your way is better than his because its smoother, however you're still causing your syncros to do some work. If you do your method while braking, its not as bad (many road racers will do this because its the fastest way to slow down). Of course true road racers only care about their tranny lasting for the race they're currently in.

I've been saying it is NOT necessary b/c that is the job of the synchros. I've been completely agreeing with you guys on that point, however the synchros will do less work if you double clutch vs just straight downshifting. (I say less instead of none at all b/c noones perfect)

Umm your a idiot. The way he does it now is the proper way to shift especially on a track. It puts actually less wear on the clutch and syncros.
Your an idiot with no actual proof, show me some sources that say that double clutching wears out a clutch and synchros faster than straight downshifting....

The only reason I would ever downshift in the way he does it is to save time on a track b/c all I care about is the faster time and I have no concern for the health of my car.
