haha cool thread. i wish i would have found a thread like this 3 years ago...
Cool info on the double clutch rev match downshift and single clutch rev match downshift.. i never tried the double or really understood the concept but its good to know its not really necessary as the new synchros are much stronger so the single works fine. |

I've just started learning how to drive stick and while I have the basics down, I think my biggest problem is getting going from a stop in 1st.. I can do it slowly but I'd be pretty shaky if I had to do it on a hill or in heavy traffic.
Right now I've found the smoothest way (or only way without stalling) for me to get going so far is to release the clutch , wait for it to hit the engagement point and the car to start rolling a little bit, then i give it a little bit of gas and release the clutch all the way. Since this does take a little longer than I'd like, I was wonder if this is the correct way and I'm just not used to it yet, or if there was a better way to do it? I watched the "gentle launch" video on page 2 of this thread and saw that the guy would give it gas and rev up to about 1000rpm and then simply just let out the clutch smoothly - kind of the opposite order of what I was doing but seems a little more straightforward. Is that a better / quicker way to get going? Thanks -edit: just thought of another question. I read this whole thread and a lot of the discussion was on rev matching on downshifts.... If you were slowing down to take a turn on a normal city street you wouldn't need to rev match do you? Because you are braking as you clutch in and select the lower gear, so by the time you let the clutch out you should be down to an appropriate speed for that gear at the rpms you were already going right?

I want to ask you guys for opinion about the way I downshift now:
I'm still trying to master heel-toe technique, but when I drive in the city, I tend to use my old way of shifting. Which is, for example, I'm in 4th coming to a corner, I brake, clutch in, shift into 3rd, keep braking, shift into 2nd when the speed is right, then declutch and accelerate. The reason I don't skip the 3rd is I think I reduce the work of the 2nd gear's synchro a bit, as I increase the speed of the flywheel in 3rd before going to 2nd. From 4th directly to 2nd can feel a bit rough. This way I know I'll wear off the clutch's "spring" a bit by holding it in all the time, but I guess clutching in and out of 3rd also puts a bit stress on it as well. Do you guys think this is OK? Do I actually help the synchro at all by going into 3rd before 2nd? |

To answer your second question, I shift quickly all the time even when I'm just cruising smoothly and because of this I rev match all the time. Since I do it every downshift, I get a ton of practice. You don't really have to rev match but, as I said, I do it every time because it's better for the car and makes it smoother for my passengers. When you get it right, you can't feel the shifts at all. |

Question: how do you shift from 1st to 2nd smoothly and quickly without the "pause" where the car coasts during the shift? When I do the 1-2 shift, slushbox drivers usually get dangerously close to my back.

Also make sure you ease into the first part of the throttle, then press farther. Don't mash it in. Hope I am being clear.

Haha I've never touched that stuff. I'm slow enough as it is.

Ideally I want to be able to shift like a slushbox, if not smoother and just as fast. 8ms DCT shifts, here I come!!! Just kidding. |

noob problems i'm having like most
-- I keep my foot on the clutch even after changing the gears. -- The harest is starting the car, that 1st gear clutch/gas ratio is so dreaded the each stall takes away your man hood. Let's say your in 5th gear, and you see the light turning red, right now I brake a bit than go straight to neutral for a complete stop. Than put it in first gear and try to start(this is where I stall) I do keep my foot on the clutch when reversing for some reason, gotta fix that. another q, let's say you just switch from 3rd to 4th and you need to make a turn on a normal st, I go from 4th to 2nd, I skip 3rd apply the brake and hit the gas. All in all it's been really a pain, I have yet to take it on a really busy day(bumper to bumper) btw I'm learning on a 93 honda before taking delivery of a e92 shortly |

I used your suggestions today and it helped a lot! Thanks! Keeping my foot slightly on the gas while shifting makes everything smoother.

So I took the car out during slight traffic, rain and darkness. Not too bad till I hit the a busy drive thru. I stalled like 10x. I didn't think of any other way than keep putting it in neutral than once I got enough room in front of me to not the damn car I put it into first and go. Problem was I kept releasing the clutch to fast because i had to brake so I would not hit the other car. At one point I even rolled back a bit.
How does everyone else do a busy drive thru? |

letting out the clutch fast is only good for upper gears or when you are in full acceleration mode and not in traffic. In traffic, always gently clutch out AND throttle in gently.

I highly recommend Standardshift.com. Make sure to check out their FAQs and the forums too. There are ridiculously knowledgeable people there. Some of the things said here are bad for your clutch.
