It's just so strange that double clutching and heel-toe has to be used on normal driving on the street. I don't see a need to it except for track when your rev has to be maintained at high point. Why would you want to maintain high rev on the streets? Bring it to the track. don't endanger other road users on the freeway and pedestrians on the streets.
I dont see how revmtaching and heel toe is dangerous on the street. I use it on the street mostly so i dont get that jerky motion when i downshift (your passengers will appreciate it) but also so that the synchros last longer. Its not always to maintain high rev, its to be in the right gear at the right speed.
agree with cymax.
Safe driving is more important on the street than going fast. Slow down when approaching a corner or intersection, then you don't need double clutch/heel-toe/rev match. The rev would be low enough for the lower gear to engage, without killing your synchro/clutch/gearbox.
People are watching too much BMI... even the pro racers in BMI sometimes make mistake (misshift, etc)...
^^ Yeah, that's my whole point. Slow down approaching corner/intersection then you don't need to do those hectic stuff. You rev much when you want quick response from the car. That's my own opinion. Oh well, I believe each individual has their own driving habbits and techniques. My clutch/synchro hasn't given me any problem so far...
each to their own i guess, no matter how low your revs are they aren't going to be matched with the lower gear and therefore get that jerky motion. Revmatching is not that much different from a regular downshift, just 1 extra step which is to blip the throttle. I'd suggest learning it in a empty carpark or something though and not on the street, especially the heel toe where your foot may accidentally slip off the brakes.
In my car, I just need to be gentle when releasing the clutch... no jerky motion.
yeah, you'll get jerky motion when you throw your clutch when down shifting...
Also, if heel-toe is not done correctly can cause the car to have a sudden hard braking when you are twisting your ankle towards the accelerator and therefore causing the car behind you to brake hard.
In conclusion, do whatever you want on the road but drive safe and don't endanger other road users is your responsiblity and top priority...
cheers....
sorry for the noob question but what about just neutraling the car? i understand rev matching and stuff for corners but when you're going in a straight line and slowing down for a red light, would you rev match down all the gears? or do you just downshift to all the gears? can't you just put the car in neutral and brake? wouldn't that not affect your synchros or your clutch at all? this is how my dad taught me to drive and it seems like most old asian people drive like this(family friends/etc)..i didn't even know i had to downshift until my driving instructor told me to so now i downshift(don't quite understand why though, my instructor said it was dangerous or something?) till about gear 2 and then just clutch and brake cos my first gear won't go in unless i have completely stopped.
need this to be cleared up because some of my friends just clutch and brake and laugh at me for down shifting and wasting petrol..
thanks
Its probably a saftey thing. Always keep it in a gear. At least then if you do loose consiousness for any reason then engine/gear braking will slow the car down.
No, just putting it in neutral is dangerous and no one recommends it because in an emergency if you need to accelerate you wont be in gear to do that. Also because putting it in neutral means there is no engine brake at all and you're relying on your brakes. Sometimes I'm lazy and dont downshift but I still make sure I only clutch at the very last second before it starts stalling.
As with any skill, you need to have sufficient practice to be proficient at it before you start doing it on public roads with other traffic. Same as with your driver's license. You get your Ls and then you need to get sufficient hours of road practice time. I agree with you that we should drive safe and responsibly. Hence, anyone who wants to use heeltoe/revmatch/double clutch MUST have sufficient practice and be proficient at it before using it on the street.Quote:

^further to that, once you are proficient, there is absolutely nothing unsafe about it at all... its second nature to me now... but a light flywheel, heavy clutch and solid mounts means sometimes you need to do things to make the ride as smooth as possible
