Shifting into gear while moving???
 
I have noticed that when I try to shift into say, 1st or 2nd gear while moving at about 30mph, leaving the clutch pressed in till i make the turn, it is seems like there is a bigger gate to get through. Sitting at stand still shifting into any gear is like nothing, but leaving the clutch in shifting while moving seems more difficult.
Does this hurt the clutch or flywheel?

why are you clutch-ing in till you make the turn going 30mph? get into 2nd BEFORE the turn.

your gate will be stubborn into 1st gear even if the SRM is turned on as you need to time the entry just right. you can, however, tap the throttle to assist the blip (SRM turned on) making your entry window a tad longer.

honestly you need to learn MT on a non-SRM car (or turn it off on the Z) and practice blipping the throttle while you brake.

no need to ever shift into first unless fully stopped. i dont even go into first if i slow down to like 5mph. and as kenchan said no need to press in the clutch to turn. always wanna have a the car in a gear going thru a corner.

i believe every trans has some kind of half locking mechanism thingy of some type to not let u throw it into first gear easily unless almost fully stopped

Be in gear through the turn. Down shift in a straight line, like braking.

:iagree: also.. as others said above 1st is to get you moving.. even if going 5-10mph I am going to go to 2nd. The syncros dont take kindly to slamming it into first at any speed..

if I think I am gonna start accelerating again or in traffic I use 1st all the time. Even with SRM turned off I have no problems downshifting into first.. just gotta sync the rpms' manually. No biggy.

It's harder on the synchros if you shift into a very low gear when moving at a high speed. The resistance you feel is the synchros trying to do their job.

So for example if you are on the highway going 60 mph and you take an off ramp with a sharp turn at the end and you say "OK, I will need to be in 2nd for that turn, so I will just push the clutch in now and shift to 2nd at 60 mph" you are going to feel significant resustance and doing this often will cause a lot of wear on your synchros.

I have been driving MT cars all my life... plenty of experience with heel-toeing and dont have the SRM... You really feel it goes into first with ease as it does when down shifting into other gears? I am not saying it wont go into the gate.. but I have always found ALL MT trans hate it

Agreed. You should be in gear before you turn your wheel. Also, down shifting into 1st at 30mph is a bit excessive - yikes!

As long as you bleep the throttel and match the RPM speed to wheel speed then you are ok. You can be in 1st gear at 30 if you really wanted to LOL. The max gear speeds are below. But like people mentioned earlier, you MUST be in gear through a corner to keep the wheels locked to the engine. Engange the clutch either before the corner or as you exit the apex.

1st - 40

2nd - 65

3rd - 90

4th - 115

Please dont lol

if you are rolling, stick in second.

a) wont make u look like a "because race car" driver. (noob with a mt)

b) first gear on ALL transmissions is not easily activated at speed. will it? Sure! will your trans enjoy it? no

c) refere to a)

elmz 07-27-2012 10:34 AM

^This. There is no need to downshift into 1st, ever. Maybe on a track, maybe...:rolleyes:

dP3NGU1N 07-27-2012 11:34 AM

^If you're in first gear on the track I think the term is "You're doing it wrong" :p

Yes, if you double clutch and rev match so the synchros don't have to be overworked, you can downshift into 1st at 30, but if you did that then you won't feel any additional resistance and you wouldn't be posting this thread.

The point was that he shouldn't be cramming the trans into any gear at any mph because yes, it's hurting the car. :tiphat:

regarding 1st gear: LOL well I never said you should... I said if you "really wanted to you could" I wouldn't recommend it though as the the second gear has plenty of power band to get you up to speed quick :)
