I'm just curious if anyone can talk about shifting techniques from as lax as daily driving, to as competitive as racing down a road course or bombing down your local mountain pass.


Whenever I'm just moving around town, I do use heel-toe shifting when slowing down for turns/corners.

Downshifting without blipping the throttle almost always ends up with a jerk, so it's mandatory to modulate the throttle and have the engine RPM at about the same speed as the drivetrain.

But I don't use the insane pivot-your-foot-on-the-brake-pedal technique that racing drivers use, I simply use the full width of my right foot and brake with the left side of my foot, and modulate throttle pedal with the right side of my foot to match the revs to the drivetrain speed as I let off the clutch pedal.

Reason why I use the full width of my foot is because the pedals aren't very well suited for the "racing style" heel-toe shifting. The racing style heel-toe shifting is demonstrated by Keiichi Tsuchiya here:

The benefits are win-win:

1) reduced clutch wear
2) extra enjoyment while driving


Please, everyone post and elaborate, the car section needs more discussion!

I've been working on downshifting the same way, using the full width of my foot, because my pedals are too close together to do heel-toe. I'm gettin' there.

I couldn't use the width of my foot to downshift in the Integra. They're too far apart but in the RX7, I can. I've been doing it for quite some time now but I haven't gotten use to blipping the throttle so it's either too much or too little.

I heel-toe double-clutch too. My pedals are close as well, so I use to just use the right side of my foot to kind of bump the throttle, but after I practiced a little and tried different techniques, I was able to get it down perfectly. I now press down the throttle with my heel. I'm able to push it very far down now, so I can get very high revs and stay at the optimal speed at all times with no lag.

I also rev-match when shifting up. I'm able to shift extremely fast, and keep up the revs so I can pull my foot off the clutch very quickly, and put the throttle right back to the floor immediately after taking it off to shift. It's very efficient, and there is no lag. Just extremely fast and smooth acceleration.

When you perfect your rev-matches and heel-toe double-clutching, you are one efficient driver. Just a flawless stride. Not to mention it's incredibly fun!

ya too bad the clutch pedal is slowly disapearing...in about 20 years or so all cars will be hydrogen fuel cell and have boring poser paddle shifters

How the hell am I supposed to press the clutch then?!

I hate left-foot braking.

I'm not a fan of stalling. And shifting without pressing the clutch pedal will destroy the synchronizers.

Besides, heel-toe downshifting is more satisfying and helps slow the car down.

Get to 4th gear, rev to redline, shift to 3rd than pop the clutch, quickly push it back in, rev up, pop the clutch and rip the ebrake.
Its called Exturemo Advansu Sheeftrock !!

Oh man, that gave me a good minute of laughing!

I've tried the handbrake "drift" on a 1 lane mountain pass. Almost stalled because I forgot to kick the clutch

Fyi, double-clutching is pretty much useless since synchronized transmissions became pretty much universal in the 80s. Rev-matching on an upshift is just ridiculous and pointless unless you keep the clutch depressed for 17 years and the revs fall off completely. Also for you guys using the right part of your foot to rev the engine in your heel-toe you should really practice doing it with your heel instead. I know it's really difficult for guys with big feet since it's cramped in there anyway, but the reason is if you run into a situation where you are threshold braking or experiencing a lot of brake fade and you have to press the brake pretty much to the floor you may end up having to release some brake pressure to get to the throttle with the right side of your foot (which would put you off the road) or you may even end up pushing the throttle and brake at the same time which would be equally bad. If you use the toe/ball of your foot to press the brake it allows you greater control and you can use the length of your foot to get more articulation and you will be able to apply the correct pressure on the brake and gas with practice. As with any of the techniques in racing, they are all simple enough to learn but they just take a little practice to master and if you were willing to go this far Im sure you can get the rest of it.

I'm talking about performance driving. Making every fraction of a second count. Not casual driving. When you're entering a corner at 80 MPH in 3rd gear, you can't down-shift to 2nd gear properly, or quick enough without heel-toe double-clutching. Especially in wet conditions. You'll lock up and spin. Rev-matching is not pointless when time matters. When done right, you can pull off the clutch as if it were on fire. If you pull off the clutch too fast without properly rev-matching, you'll lock up. Sorry if I wasn't specific enough on driving style. All of this also depends on the individuals style. I brake late, and take corners at high speeds. Some may brake earlier, entering a corner at lower speeds, and not have to double-clutch. To everyone reading and learning: Find your driving style. Figure out what works best with you. Then you can figure out which techniques work best with your style. Take your time, and don't go rushing in at full throttle. Go easy and progress.

Haha You've got that right! I can't stand all those hybrid transmissions and paddle shifters, slap shifters, etc.
