Without double clutching doesn't the transmission not match the speed then? Thats what the whole point of double clutching I thought.
here is a nice read from xviper:

I was wondering how to learn rev-match your car so it can be smooth when down shift? Is this something that you have to learn on your own or there's book for it? Rev-Matching is using heel to toe technique but it's hard to match perfectly rpm. What happended when you over rev or just down shift normally? Is it bad for the car when over rev or down shift normally?
I'll only drove stick car for only about 4 months. Thank You for all your help

learn to rev match first....then learn heel-toe...
i bit of advice when you start to learn heel-toe....it's easier to learn the harder you brake

I do it 90% of the time on downshifts. 10% being times where it isnt even needed(parking lot,stop light ect)
Started driving that way after watching tons of car videos and now I do it in every car by habit. Pisses me of being a passenger with a non heel/toe driver. So much more smooth when done correctly..
Plus this car is SOOOOOOOOOOOO nice to do it with. Typing this makes me want to go drive. 2am perfect topdown vegas weather. IM OUT OF HERE!
p.s this car for some reason makes me wanna drive at stupid hours of the night

And another thing. I have seen alot of people heel/toeing. Like literally heel and toe.. Depending on the car it typically isnt like that.
Its more of a ball of the foot on brake and outside edge on gas.. You roll your foot down and away sorta for the gas blip.
Just in case a few people try and wonder why its so uncomfortable. Have corrected a few people who dont know why this "heel/toe" is such a hard thing.

question: do you guys double-clutch if you're downshifting more than 1 gear? i.e. 5th to 3rd, double clutch, or rev match? Or do you do a quick 5-4-3 with rev matching?
I've seen Honda bulletins for certain cars that had premature synchro wear-out due to skipping gears in upshifting (i.e. Mr. Gas Miser shifts 1-3-5).

That would include the S2000 too.. don't skip shift up or down. Keeping 5-6 together is most important.
Personally I'll do a quick 5-4-3 with rev matches if I want to skip from 5th to 3rd. The syncros aren't designed to deal with such large changes in speeds, so when you skip shift, you put too much pressure on them and they can strip. There's plenty of pics on here of the 5-6 syncro all chewed up from skip shifting.

I doubt that an occasional 5 -> 3 down shift without double-clutching will cause any trouble. Just don't make it a habbit, and repeat it all the time...

I guess this happens mostly because people accelerate hard during 1->2->3, and then their speed is already beyond the speed limit, and then they shift from 3 (or 4) to 6 for relaxed driving. The 6-th syncro is not built to deal with this much speed difference; and hence the problem...

). Plus, I'd think it would be easier to misshift if you're jumping a gear (like hitting 5th when you go 1st to 3rd or, worse, hitting 2nd when you're going 6th to 4th).
