^^Lol!

I see what you did there. Confusing MT functionality with AT shenanigans

Just a couple of notes:

NEVER ask about racing if you don't even have the basics of regular driving, bro! LOL.
IMHO, when coming to a stop, it's very easy to just put the car in neutral when you know that you are coming to a complete stop. You also get much better gas mileage as opposed to downshifting. You also preserve your clutch. The tricky part is if you have to put it back in gear (like if the light turns green before you come to a stop....). Only experience can teach you which gear associates with the speed that you are going. I will say that the G37 clutch isn't the best.

My last standard I down shifted all the time. At 150k miles I was still on the orignal clutch (and in good shape working well mind you) and on top of that I was able to get 90k miles out of my brakes (only had to turn the rotors and do pads). Down shifting is a GOOD thing. Why do people not understand this? It does not use hardly any more gas if any and puts very little additional stress on the clutch if done PROPERLY!

Wrong. It has been explained already but I'll give you the cliffs. When you coast down in neutral, the engine is at idle, when the engine is at idle, it's burning gas. When you coast down in gear, the fuel is shut off, Exept when the rpm's get low enough to the point the engine starts to stall. The only wear on the clutch is if the rpm's are not matched during the downshift, and even that is very minimal, nothing like the wear that happens when you take off from a complete stop. Of course if you downshift from 6th to second at 55 mph and let the rpm's drop to near idle then there's gonna be a driveline shock that will take its toll over time. But I'm sure that nobody here is dumb enough to do such thing.

I'm gonna try that. Thx

I'm gonna try your method also. Thx

There are a bunch of myths when it comes to coasting, ever since the hypermiling fad kicked in with over zealous Prius driving tree-huggers who wanted to hit the advertised mpg's the Prius fails to get. Like mentioned earlier, coasting in gear does not put any more strain on the powertrain than normal driving. Whether I'm driving my AT G or my 5MT beater, I always downshift and use the engine to help slow me down. And on the G it's even fun since it has auto rev-match.

I don't do it to save gas since since the gas savings are almost negligible, I do it ecause it's a good habit to ALWAYS be on the right gear. But if you want to save every little ounce f gas that you can then do what hyper milers do. Turn off the car while coasting down in neutral, and good luck since you'll need it.
What I do Is throw my car in neutral and just coast to the red light because I know I will be stopping and I want to preserve the clutch by not downshifting. I only downshift when I'm at a high gear and if I need to be at a lower gear.

To the OP, make sure you set aside ~$2K for a new clutch sometime in the near future. Possibly more depending on other driveline damage
Why do you say my clutch will go bad? Is it because I'm launching incorrectly?

Maybe a forum member around you would be kind enough to meet up with you and give you a few live pointers and demo proper 6MT driving and what not.
I'm in Skokie, Illinois.

Because dumping the clutch and other 'racing' type abuse will tend to cause premature wear, and may potentially damage parts of the driveline.

Skokie, eh... scary! Very scary.

I know the basics I been driving for a while now. I never raced until I got the basics down which is how to move forward which I have down pretty good but I just need a tip on how to launch hence me asking the question.

I only downshift if I need to other then that I usually just coast.

I dont do it every day I just want to know how to launch that's why I'm asking. LOL I know its scary but I don't F around in Skokie.

Actually if we are going to debate, let's just be TOTALLY correct. I love the way you elegantly (but INCORRECTLY) typed "Wrong" and then yourself typed INCORRECT info.

Here is the Truth... THERE IS NO DIFFERENCE IN GAS MILEAGE... when comparing downshifting to simply engaging the clutch or drifting in neutral to a stop.

If you still think I'm incorrect put some money up and then go film your MPG gage doing BOTH.

And far as damage to your clutch, I will change that to wear on your drivetrain/engine...

My bad... you mentioned: "Second question do you have to completely push the clutch in to switch gears and also when starting from first gear? Third question before I ask you guys the question I just want to let you know I never stalled but my question is getting of first gear I always jerk what could I do to stop that?"

So those are kind of "the basics" of driving a manual... So I thought you were still working on it.

ALWAYS push the clutch ALL THE WAY DOWN! Now the weird thing on our cars is at what point is the clutch disengaged... There is a lot of play in the clutch. The only way to get rid of the "jerk" is practice and learn at what point/rpm/footspeed should you release the clutch. I'm going to pay closer attention tomorrow and follow up if no one else has already answered!

Enjoy the car though. Im glad I went with the 6MT this time!

No problem bro that's when I first bought the car and was learning on how to drive but I got everything perfected besides launches but as I said before I don't plan on doing that everyday its just once in a blue moon if I race someone. Thanks for the help tough and I hope you give me the answer tomorrow on how to not get the car to jerk because I'm still kind of working on that.

Settle down Beavis. Fist of all I guess some here have a bad case of selective reading, so I don't have a choice to quote myself... Again.

I am well aware that the gas savings are almost NEGLIGIBLE, meaning almost insignificant just in case that's too big of a word for you. The wrong statement I wanted to correct is when it was said that coasting down in gear burns more gas. That is a WRONG statement. Just like how coasting down in gear puts more strain on your driveline is just as wrong of a statement.

In modern fuel injected vehicles, fuel is shut off while engine braking. While in neutral fuel is being injected to keep the engine idling. This is not a matter of opinion, this how it works. This is why I was clear to say that the gas mileage difference is negligible, and that I personally downshift because I like to be on the right gear just in case, not because I want to save gas.

Love all this talk about rev matching/double clutching LOL.....


None of this is necessary, because these are synchronous manual transmissions.

Double clutching is for pro shifted/face-plated transmissions.

So much rice...........

OK Bro! Here is what I noticed (and this may be a little babying) but if I took it to 1000-1500 rpm and count "1" then let my foot off the clutch by the time I counted "2" it was smooth. So essentially around or a little less than 1 sec, there is no real jerking. Thats just for normal driving. But I don't really launch this car. If I did, I'd probably do that around 2500 to 3000 rpm.

The problem is the range that the clutch pedal has. There is a LOT of range which makes it difficult to judge when you can let you foot off. It's pretty unique to our cars but there is actually a fix that someone wrote a DIY for...something about replacing the spring. But Im getting ahead of myself LOL. See how that works.
