Double clutching

Question : WHAT is double clutching ? Is it good ? What is the advantages ?

I read somewhere that double clutching will prolong the life of your gearbox. How does it do so ?

Answer : Double clutching came about in the days of "crash" gearboxes when there was no such thing as synchromesh and one needed to match gear speeds in order to shift down or else there would be a great deal of gear grinding and sometimes inability to even affect the shift.

In later years, even when synchronisers came into use, double clutching was used a lot in competition in order to get smooth downshifts while braking into corners.

Today, most competition vehicles use sequential gearboxes that shift so fast that double declutching is no longer used.

On road cars, people who double declutch probably do ti to hear the sound of their noisy exhausts !
