better to over rev or under rev?

So we all know how difficult the our 6MTs are to drive smoothly, especially that infamous second gear... I've been driving manual transmissions for some time now... but the G i still don't get it right on 100% of the time.. with second gear it's a lot of guessing and hit and miss and trial and error.

So you give x amount of gas at x point and you either under rev, over rev, or get it right on... I know they both put wear on the clutch, since the engine and clutch are spinning at different speeds so at the point of contact there will be some rubbing until they match speeds.. but i'm wondering which one puts more wear on the clutch?

The underreving definately FEELS like it's doing more damage since it makes your car jolt suddenly.. It's a lot easier for the clutch to slow the engine than ti is for the engine to slow the clutch since it has to slow the entire weight of the car as well...

Anybody know for sure?

overring would burn the clutch just as much as underreving (assuming you release the clutch one you realize that you've given too much gas) i think.

overrevving is better, ide rather burn teh clutch than put strain on the tranny.

i have no prob driving it smoothly, jsut make sure u release the clutch well, even from 1->2 its smooth. give it some practice, dont practice hwen there are a lot of cars around.

the only time i have smooth shifts into second gear(1st to 2nd) is when i'm flooring the gas on 1st (at about 6000-6500 rpm), speed shifing as fast as i can.
-by the way thats a sweet *** feeling ^^

other than that, my second gear is pretty jercky

i'd also vote for over rev vs. under rev

A couple of you guys, including the original poster, really need to learn how to drive MT's better. The G is not a hard car to drive stick in at all.

I'd be embarrassed to post such a thread.

For shame, mc2, for shame.

I've never had any trouble with shifting into 2nd gear. Was that an 03/04 tranny issue?

Just let out the clutch slower...then you can gain more window.

If you're talking about downshifting it's better to over rev and let the
clutch out slowly. At lower speed downshifts, you need to keep
a tad bit of throttle while you clutch-out as the flywheel is light and
the AC compressor will throw off the spin down.

Just practice and you'll get the hang of it. a trick for a smooth
shiftup is to roll off the throttle gently...even at wot.

I don't think there is really a correct answer for your question other than either is bad. A little more practice and you'll have the hang of it. I actually think these cars are pretty forgiving and easy to drive as standards.

Wow, that's a very arrogant statement of your part. I wouldn't talk if I was you .

That's unless you were sarcastic, but I sure didn't feel the sarcasm in that post.

Oh, i can drive an MT fine, thank for your input though. The G is not difficult to drive for me, only the 1-2 shift is difficult to pull off smoothly every time for me. It's pretty common for many many people on the forums. There are some members on here that have been driving MTs for over 20 years and still have difficulty with the 1-2 shift.

Doesn't letting the clutch out slower = more burn?? I can shift it smoothly if i let the clutch out slow, but i'm pretty sure it will be worse on the clutch than just dropping it basically since if you let it out slowly if the clutch and engine speeds don't match and you have the engagement at half way, wouldn't that be about half of the pressure of the clutch on the flywheel allowing the two to rub more than if you were to just to let go of the clutch completely?

No problem here when I was stock. The JWT 14lb flywheel forces you to shift even faster and more smoothly. I've to master the JWT enough to say it is definitely streetable. Stock is even easier. Clutch modulation is key...it's not just an on/off switch.

I can modulate the clutch pretty well, but like kenchan said to slowly let the clutch out, that just creates more wear on the clutch.. You're a lot better off just having a jerky shift then. I can shift it just fine everytime if i modulate the clutch.
