If you want to double clutch, more power to you. You may slightly reduce the wear on your syncro's, but unless you are making your syncros work really hard, you should have to worry about wearing them out too fast.

 

Couple notes. I never said double clutching is necessary. How much of a benefit it provides is certainly debatable, all I was trying to say is that it should in fact help. Skip shifting or if you happen to find yourself coasting and needing to select a gear it would help. As trannys get older (especially if they've been beaten on) it'll make a noticeable difference as well.

I was merely asking Billman why double clutching is never needed.. older hondas had issues with syncros wearing out, and I'll happily change my TO bearing more often and save some wear on my tranny. If the s2k syncros are more stout with little/no syncro wear then that's a good reason to not double clutch rather than just "syncros do that work."

 

I've never double clutched. That's what the synchro a are for. 190K+ miles double stock power and stock trans is still nice and smooth! Double clutching with synchro a is a waste of time. Theoretically might reduce tiny amount if wear on synchros, real world don't see it being an issue at all.

 

You did read the freeway part right?

 

Some folks make it sound like you're building the pyramids or something , we're talking about just one extra push of the clutch pedal since you should be rev matching anyway.

 

just rev match during the single clutching on downshift. clutch in, rev match while changing gear, clutch out.. double clutching is a waste of time.

 

Clearly man you're a bad driver, just accept it. Don't you know that you're either supposed to be on the throttle or braking at all times??

Oh wait, we're talking about the street.. There are exceptions to the rule. I guess no one has ever coasted down a big hill/mountain in neutral.. or been coasting in traffic and had to skip a gear when downshifting..

 

I used to skip shift in my DD all the time. When I got my S I stopped skip shifting because I learned that it is bad to do.

 

to each's own. I rev match on down shifts while heel toe. Granted not all the time but I like to slow down and have the right gear in place. Just out of habit I guess ( stupid initial D ) But up shifting i just press in the clutch and let go of the gas a little later to let the RPM climb a little.

 

Why do extra work when it is useless?
