So all you have to do is rev match and you'll be fine? i think you shouldnt own a s2000 if you cant...

 

your post doesnt make sense

 

Sure it dose. If you skip gears like going 2nd to 4th and make the revs correct going into that gear you should not hurt the syncros. I guess a better example would be down shifting, clutch in, neutral, clutch out rev engine to correct rpm, clutch in, gear shift realese.

 

it's been discussed numerous times. https://www.s2ki.com/s2000/topic/102...ifting-is-bad/
I dont skip shift esp upshift. I always row thru the gears
I skipped on my Z and 5th gear developed an occasional grind

The issue isn't whether or not your synchros can handle it, it's about premature wear

 

In my mind it is alright to ship downshifts in the following situation.

Driving in traffic and you make an emergency stop. 40mph in 5th gear, now 10 mph. Only then would I just place the transmission into 2nd or even rev match into 1st depending on situation.

Does this answer your question OP?

 

The OP is describing double clutching, not just simple rev matching, which will allow you to skip shift without wearing out synchros.

 

So you don't wear out synchros by double clutching, but do you wear out your clutch and springs earlier?

 

You dont wear the synchros when you double clutch. So if you are going to skip you can either "row through the gears" as in push in the clutch, go through whatever gears you are skipping and then release the clutch. OR you can double clutch. Double clutching allows the input shaft to match the speed of the output shaft.
Double clutching does not wear your clutch out either assuming you are getting the rev matches correct. If you are dumping the clutch without revmatching it will wear the clutch.

Double clutching takes more work and it is slower than rowing through the gears.
If you're in 6th at 40 and you come to a right hand turn that needs to be taken in 2nd, if you go directly from 6th to 2nd at 40, it will shoot the RPM up from 1.5k to 7k (roughly), which is a big thing for the synchros in 2nd to handle to bring the input shaft up to speed.
but if you slow down to 20mph and go to 2nd, it's not that big of a deal because the RPM jump isn't going to be as great.

So the rule is a) never skip upshift or downshift. If you are going to, push in the clutch, row through the gear you are skipping and then release. b) drastic high rpm changes when downshifting still requires rowing down the gears or double clutching. Rev match is ALWAYS mandatory for your clutch life. c) low rpm and "already slowed down to target RPM range" doesn't require it, you just skip it. not ideal but not a big deal. I always row through the gears anyway because it's habit.

It's always good habit to row up and down and go sequentially for track driving, canyons, etc. especially in a car like the S2000 because you want to be in the powerband and the right gear whenever possible. I treat my gear choices like an automatic transmission would.


Only problem I have is, because I never skip and I always row through the gears.. sometimes I find myself rowing through really fast when in an emergency. In a true emergency I should just skip the f@#kin gear and get out of there instead of worrying about my synchros but it's become habit.

 

And no, your first post didn't make sense. Not sure if you were asking us, or telling us.

 

What's the point of skipping gears? All 6 gears are there for a reason...
