58,700mi without clutch TSB, including 1500mi at the track. I don't think so.

 

You don't do it when upshifting to improve times. I'll only do it when it's cold outsite and I just started the car. You double clutch to dowshift. Racecars without syncronizers just upshift whithout using the clutch.

 

yes! thanks to synchros, the need to "Double Clutch" is no longer relavant.

 

This is not true. Anytime you're rev-matching into a lower gear you should *always* double-clutch, synchros or not. Synchros *help* match speeds but they don't perfectly match the mainshaft speed every time.

I think double clutching is done mostly by truck drivers with exsessive loads.

 

On the other hand, you can double-clutch not just to match the rev speed, but to over rev. This is done to break the back tires loose going around corners. You are "popping the clutch". I don't recommend this but it is done in some competitions such as drifting.

 

Double clutching was also done by Dom (Vin Deisel) in TF&F. So you know you have to do it to drive right!!!

 

But if said truck drivers discharge that load prematurely, would there still be the need to hit it twice?





s2k1xlr8, I can break those tires loose just as easily by only putting the clutch in once, revving it up, then side-stepping the clutch.

How in the world can this be done smoothly, on a constant basis, and without grinding the gears?

 

Double-clutching, particularly in down-shifts is just automatic for me. I learned to shift that way when I was growing up. I didn't even realize I was doing it till I picked up my son this last Thanksgiving in Cleveland. On the way through some corners, he ask me if I was double-clutching. It wasn't till he ask that I realized I was.

While this is not necessary to properly operate the S2000, It won't hurt, if done properly. Missing a shift with syncromesh is no big deal, but if you learned to shift manual, non-syncromesh transmission it's awful hard to change the habit, particularly when it sounds and feels so right
