Double-clutching...Man, that takes me back a long ways, back to that old Datsun 2000 I used to have (a fairly rare two-seater Vert) back in high school. I remember my buddy got an MGB and I thought it was so cool that you did NOT have to double-clutch.

If you didn't double-clutch on that Datsun 2000, they were definitely grinding.

Now that's funny!

It's the way I was taught (I'm 48 now), and it's completely natural to me.
I've tried double-clutching on downshifts, but it's really pointless for me.
I rev-match so smoothly I don't see any reason to do anything else.
Plus, not rev-matching is extremely hard on the clutch & transmission.....is it not?
No, its not. Modern manual transmissions will go well over 100,000 miles with no noticeable wear on the gears or syncros without rev matching.

Basically what your doing when you double clutch a synchronized transmission, you're saving wear and tear on the synchros. Nothing wrong with that at all.

There isn't anything wrong with it... but its just not needed in these cars. I really doubt you will wear out your syncros as opposed to something else on the car. One thing that many people forget about with these cars is to change out the clutch fluid. When I got my first C5Z, I didn't realize how often I should check/change it. Now I do constantly just to make sure I don't wear out my clutch.

Point is, double clutching is just fine... but you will be just fine not doing it. Older transmissions it was almost required, not so much these days.

After 35 years driving tractor trailers for a living double clutching was my natural way to shift, but I cannot get a smooth shift by double clutching my M6 Grand Sport. I think it's because of the close ratios.

I do rev match on down shifts, but my heel & toe procedure needs much improvement. I have a wide foot, but when my foot is comfortably on the brake I can't always roll my foot on to the gas.

I don't want to get a gas pedal designed for heel & toe because i'm afraid of catching it in an emergency stop.

When I was a kid we had cars with 3 speed stearing colum shift. You had to double clutch to down shift to first if the car was moving. Otherwise to shift to first you had to come to a complete stop.

I do it almost every shift. During spirited driving, I also heel-toe a lot. Its part of the joy of owning a manual transmission.

Hey Sub just to let you know, this thread is over 1 year old and you are not supposed to post to any thread that hasn't had a post in 45 days. I have done it by accident several times, but I now try to always check the date on the thread first. Just trying to help. The mods will usually politely inform you of this rule.

Most of the times a little blip helps, it seems to put less stress on the transmission and most importantly it sounds cool.

I hate to sound stupid, but would someone very courteously insult my intelligence for a minute and help me understand this thread better? I thought I new how to drive a manual, but I admit, it was largely self-taught. Maybe I've been doing something wrong?
You are right, you are rev matching . Heel and toe is the same thing but you also press on the brake pedal (right foot brake and gas at the same time); heel and toe is a racing technique used when you are cornering and you want to launch the car right after in lower gear .

Always! That M2W is so beautiful to listen to when I blip the throttle. Music to my ears. In fact, after two months of owning the car I've used the stereo maybe three three times.

Correct that is exactly what I did on my 55 Studebaker Champion.

The Vette is not really conducive to heel-and-toe IMO, mostly due to its 'lazy' (and non-adjustable) throttle mapping. I have 'heel-and-toe' pedals, but mostly just rev-match on downshifts, because my right ankle is just not flexible enough to depress the gas pedal what is needed for a nice downshift. Maybe at full braking, but don't do that much.

Do you want to see not only heel-and-toeing, but also keeping the engine (turbo) in the powerband AND not killling spectators all at the same time? Watch the master in action (Walter Rhorl):

Then why the heck not make threads over 45 days auto lock themselves? Most other forums ask you to search first, and not start a new thread when there's an old one already, so most folks assume that's the case. There's an easy way to achieve what they want without any hassles. It's like leaving a jar open with candy inside and expecting your kids to not get any. Just close the freaking jar and problem solved, right? . Just saying.

An EE heel/toe gas pedal and a sprint booster make for excellent heel/toe downshifts. That and a bit of practice too...well, a lot of practice.
