Rev Matching

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.

I've always rev-matched when downshifting.
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?

Im curious about this term "double clutching" I have operated some heavy trucks over the years and the term was used to describe the method for shifting a box that wasnt synchronized. Im curious if this is a caryover term? Why would you try to do this to a fully syncd transmission? Simply releasing the clutch in between gears? Im not sure I follow.

Yeah, but there isn't anything wrong with double clutching, is there? For the record, I don't double clutch and yes, I roll in neutral to the lights and I don't buy that keep it in gear stuff just in case because around here, the traffic is so tight there isn't anywhere you can go if you had to anyway.....now on my bike, I never leave it in neutral, but with that you can sqeeze into almost anything to get out of the way.
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.

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. 
....Now I had a 49 Ford Convertible that I had to double clutch going from 2nd to 1st...

Man, I feel lost. What are we talking about? When I down shift, I give the throttle a little nudge to make the rpm go up to compensate for the lower gear so the car doesn' buck and surge and all when I get the clutch out in the new gear. Is that what we are talking about? Doesn't everyone do this--seems like it would be a very jerky downshift otherwise? If that's not what the discussion is about, what IS it about?
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?

. 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.

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.
