Unless I missed what/who you're directing this towards...changing gears in a corner has nothing to do with rev-matching or heel-toe'ing.

Well, you know when you shift down and slip off the clutch really really fast and car shakes back and fourth and your RPM drops down really really fast? Well...rev-matching stops that. It matches your RPM based on the lower gear you are going into, so that way, it's much smoother on the transmission. It's just a matter of kicking the gas the second you shift down, the time and position of the "sink" of how far you kick the gas determines the smoothness of the rev-match.

Hello,
I've been driving for about two years now on a automatic, and I had a few questions for people with MT cars.
1. Do you rev-match? I know a lot of people say it's redundant, and most people who drive MT cars do not, but do you? And why do you do/do not? Of course if you don't know what rev-matching is, don't worry about it. |
Be to be honest, I do. All the time to tell you the truth. And yes, like many have mentioned it here, it's extreme waste of gas. The reason why I do it all the time was that I absolutely love driving aggressively, well definitely not to the point where it is reckless, but I can't get enough of the rev-matching sound. And at one point, I had a straight-pipe on my car, and the exhaust would spit out fire when I rev-match or heel-toe. My stock is back on now, the straight-pipe drove me insane, I would have head-aches every time I drive....and god, it was so embarrassing when I went out with girls. Not just because I love aggressively that I would rev-match but because it helps you lower your gears with ease so that you ready for the turn and gives you a better power coming out of the turn. And I feel that helps in commuting. I mean, I just hate having to kicking the gas or easing off the clutch when you put your car back in gear...I hate that....

| 2. For drivers of modern cars, do you double clutch rev match? I know it further reduces strain on the syncromesh, that it's really complicated, and that very few MT drivers use this method, but I was wondering if it's worth it to learn it if I'm only hoping to drive modern cars. |
Nope, and no, you shouldn't bother with this technique, especially with the new MT cars.

| 3. For people who do rev-match, how long did it take for you to get it down to the point where you can do it with just the engine sound and not looking at the tachometer? I just wanted to get a range. |
What do you mean? Like rev-matching without looking at the tack? It took me a while, probably a few months to fully master it. It's scary because you obviously don't want to rev-match too high and blow up your engine.

| 4. I don't actually own a MT car or know anyone who has one, so what would be the best way to go about learning how to drive a manual? I would like driving school to be the last resort...but it seems like I have no choice. Anyone wanna teach me? =p |
I'm willing to help you, where exactly is Morro Bay? I live in the Bay Area and I wouldn't mind teaching you manual using my car....just know that I have a three strikes rule, three stalls and you're out for good.

| 5. Just out of curiosity, does anyone use heel and toe on a daily basis on a regular commute, or use it at all? (Excluding track-goers) |
Yes for commuting, there's freeway on-ramp that I would run up to about 55mph in 3rd and heel-toe back down 2nd at around 42mph, roughly halfway through I would gradually accelerate out of the turn. By the time I am out of the turn, I'm running around 60mph, perfect for merging into freeway. I used to heel-toe a lot more when I would drive on the mountain roads, it's where rev-matching and heel-toe'ing is more applicable and a lot more f'ing useful. I don't know about anybody here, but there's a certain joy that I get every time I hear the engine "vaaaaROOMmmmmm...." I love that to death, especially when there's a "POP!!!" and your exhaust muffles and hums loudly as your RPM drops. No matter how expensive gas will be, I won't ever stop rev-matching or heel-toe'ing, I just like it too much. And..omg...don't get me started with how exhilarating when just before you enter a turn, you heel-toe smoothly and swing your car in harder than you should so that it begins to oversteer just a tad bit so that you wouldn't understeer and then gas out of that..when every part of taking that turn smooth..oh man, it's orgasmic. It's pure joy and it pushes my adrenaline to the max and I suppose it's something that true enthusiasts can understand. When you use techniques like these on mountain roads, it feels so good that I feel like I'm a part of the road and that I'm just flowing through it smoothly. I pretty much developed this habit when I had watched in-car rally videos (from the 80s, back when cars were fully manual) religiously for hours and hours.
If you were to practice any of this, do it in a parking lot. That's where I learned to drive manual, rev-match, heel-toe, double clutching, clutch kicking, handbraking, and emergency over/under-steer counter-steering. I hope this post doesn't make me the head-fi's driving lunatic.
NOTE: Never change gears while turning, it alters the car's momentum which throws you off balance and that can result in oversteer or understeeer, or just slower time. The only time you can/should change gear while turning is if you want to shift the momentum so that you oversteer to make it easier for you to exit the turn while at a higher RPM, giving you more torque so you can exit out of the turn faster.
