If you're going to write authoritatively on a subject, it's best to at least have a *clue* as to what you're talking about.

Double clutching is an essential skill when driving real race cars with sequential racing-transmissions that have no synchromesh. It's also a useful skill to know for the street, or track, in case you ever have a synchromesh failure in your transmission.

 

I am missing the point can you explain how to double clutch with a sequential racing-transmissions

 

In real race cars, like at Skippey, you have to double clutch because there is no synchromesh. You have to synchronize the speeds of the input and output shafts, otherwise you'll get a crunch as you downshift. I still double clutch all the time on the street.

 

hhhhhmmmmmmmmmmm thanks

 

I think you're thinking of SMT, SMG, F1 systems. These are not true "sequential" transmissions, but rather normal synchromesh gearboxes with a computer-operated clutch. They're called "sequential" only in the fact that the operator can select up/down one gear at a time. On a true sequential gearbox, it is a real, physical/mechanical constriction.

 

I have been racing Porsche 997 GT3 supercups and own a Skyline with a Holinger sequential gearbox I never double clutch . I think sir you need to check your info about sequential gearbox's and how they work.

 

BEST POST EVAR!

 

Suggest you do the same.

You don't *need* to double-clutch any more than you *need* to heel/toe.

However, discarding it as something anachronistic like the previous poster did though is extremely ignorant.

There is a REASON that Skip Barber, one of the most well-respected racing schools, teaches double-clutch techniques. Oh, and they're not teaching it for 60s muscle cars either.

 

Thank you sir I will do that and I heel and toe everyday and I am sure skip Barber's Racing school know what they are doing

 

You're very welcome.

Here's a great article about heel/toe *plus* double-clutching that makes a great point for the technique even if you do have a regular synchromesh gearbox:

<~~~~getting out the firehose. =P

 

 

Everyone should learn to double clutch.

Yes Skippy knows what he's doing.

Best way to describe double clutching is never shifting from a higher gear to a lower gear but shifting from a higher gear to neutral then to the lower gear.

It takes some getting used to but worth it.

Isn't that a Malcolm McLaren song ??
