i have this question...when you're going lets say like around 75-80 can you downshift to third to race someone? like i mean is it safe to? or would you downshift to 4th? and lets say when you're going 40-50 can you downshift to second safely? I'm asking this cause most of the time when im driving and someone is revving at me or wants to go at a rolling start with me im usually going at these two speeds depending on wether im on the freeway or not...I want to know if it would be safe to downshift to those gears...cause i don't wanna blow my tranny or engine doing anything stupid like that if it is bad to downshif to those gears at those speedsm
I usually downshift to 3rd but it revs like mother and i usually have to shift a second after...it depends on the race i say...if he's pullin close i say go to 3...if he just hanging there safer to go 4th...
I don't think it hurts the engine with 3rd @ 75/80 and 2nd @ 45/50. The manual says 2nd goes to 60 and 3rd goes to 90. It's just that the engine will rev like crazy.

I've never raced anyone on the highway before but ocassionally on my long drives from Pittsburgh to NY or to Ann Arbor, I like to stretch my leg out. I usually cruise at 80mph in 5th so I would bring it down to 3rd. Just shift to neutral and then blip the throttle to about 6500 revs and then shift to 3rd, do it quick though...and it will be smooth. I've honestly done it so many times that it's like second nature. One time I had a friend in my car and I was bored seeing no traffic ahead I downshifted to 3rd and he didn't feel any jerking of the car at all and didn't realize we were flying at 110mph till I told him that I went from 5th to 3rd...and he just thought I stayed in 5th the whole time.

Yeah you can shift into those gears for more power. Just remember that you are going to be shifting out of that gear quickly when you get to redline. It is worth downshifting into the lowest gear possible for the most power.
i downsift from 5th to 3rd almost every day. hahah i love the vtec pull.
go like 3500-3700 in 5th gear downshift to 3rd. while your left foot is engaging the cluth all the way match the rpm by pumping the gas to rev the tach to like 5500-5800 you'll match the car's rpm when you engage in 3rd gear. and PULL PULL PULL on those cars.

That's what I need to practice. So do you keep the clutch in when you blip the throttle or do you double clutch it.
I have down shifted from 5th to 4th to wait to pass someone and then I downshift again to 3rd, but the car jerks. I have only been driving stick for like 5 weeks now so I'm no expert by any means.

VTECing is most beneficial when you already have some momentum going--as on upshifts. So downshifting at 75-80 into third to put it into the VTEC zone will be mostly fruitless---and short-lived.
I disagree...you want to be in the power band as much as you can and I know our car still pulls after 6000 revs. Hence shifting from 5th to 3rd just for that extra bit of power band is worth it.
When I downshift, I usually double clutch. Once you get it down, it's pretty fast. It's not necessary but I don't mind the extra foot action.

how is it worth it? You have about a second worth of power after a downshift at 6000 rpm. Now you have to shift again--time wasted--then you're out of the powerband again on the next upshift.
no need to waste time double clutching.... you do nuthing but wear on the clutch, pressure plate and flywheel more. double clutching is for trannys that use square cut dog gears w/o syncros. double clucthing wont make you faster...

i disagree, double clutching helps in the smoothness of the transfer as well and the wear on the clutch is the same as if you held it in since the re-engagement is apparent in both cases
While I agree that double-clutching isn't absolutely necessary on modern synchronized trannies, it does help in certain situations like skipping over gears (5-3 downshift for example). In a regular, single-clutching downshift from 5-3, you're asking the synchro to do a lot of work. Double-clutching in this situation is preferable.
Out of habit, I double-clutch all my downshifts. In fact, when I try to downshift regularly, I tend to mess up, since my hand/foot timing is so used to double-clutching. It doesn't take that much more time than a regular shift and it keeps my synchros happy!
interesting....just to make things clear someone explain the process of double clutching...its seems that everyone has a little different view on what double clutching is.

clutch in, neutral, clutch out+blipthrottle/revmatch, clutch in, shift to lower gear, clutch out

True, but matching revs is CRUTIAL if you are doing any "spirited" driving in a standard tramission equipped car. Heavying braking into a corner usually requires our cars to drop a gear or two to keep us in the powerband. Going deep into 4th to a 30 mph corner would be a good speed for 2nd. If you just pop the clutch out, you'll shock the drivetrain, wear the hell outa your tranny and clutch, and make yourself look real stupid(on a track). I match revs by habit in any car i drive with a standard. It really has no purpose around town, but its just habit and sounds so damn cool!

well if you're going into a turn and need to keep the revs in the power band you're gonna need to heel-toe downshift in order to keep the revs up as well as slow your car down for the uncoming turn...i guess its the same principle as double clutching but with the brake involved...something that i need to practice hehehe.

i always do it when ic ome to a stop light, it's annoying now with my TRM and i'm willing to bet it bugs the ppl around me but that's ok!
When I first started heel & toe, I did it with double clutching and found it to be insanely hard so I just kept my foot on the clutch. I just feel that I have less time to waste with heel & toe so I don't try to double clutch in this instance. However, regular driving with the need to downshift without braking, I am used to double clutching. It's really preference. I'm no mechanic but I hear what other people have to say, and it seems like double clutching is always looked at something that is waste of effort in new cars especially if you are not driving a big mac truck but others say it's easier on your synchros. Do what you will...and feel is right.

I never double clutch. You only need to do that on non syncro trannys
Down shift to the lowest gear possible for max power... no debate.
rev matching is important just give it a little rev thats all
Everybody wants to be the expert. It is not real complicated
I never down shift for stops EVER only turns when i need the power the car has enough torque to do what ever you want... unless driven in anger ( the most fun) in fact i don't even use the clutch to pull it out of gear. As i lift off the gas i just pull it out of gear and coast down on the brakes. NEVER had any problems though i KNOW there will be debate on this. But my second gen clutch lasted 270,000 miles. My fifth gen has 106,000 and it does not even shudder when I TOW my Ducati to the track no slip no muss, no fuss
