Heel/Toe Question
I have limited track experience of 7 days (over 3 events), so relatively novice. For all the events I have attended I have not been using any rev matching techniques.
My downshift methodology has been to make the shift very late in the brake zone, so the car is at it's slowest point. So if the brake zone is 100ft, I'm letting the clutch out around 90ft right before turn in. This has worked reasonably well so far (ie the car has maintained balance with no lock-up). I have practiced heel/toe in street driving and I'm pretty comfortable with it and would like to use it at my next event (in June). Based on my late shift methodology I am a bit concerned about doing a newbie heel/toe shift, transitioning from brake to accelerator, and turn-in all at the same time. Seems like there is a lot of room for error. Theoretically, if I rev match I should be able to do the downshift earlier in the brake zone (50-75ft), then the transition to the accelerator and turn-in would be a separate event. I want to get confirmation that this is the correct approach. Keep in mind, I usually don't do sequential downshifts, I just jump to the gear I want to be in (example: 5-3). Thoughts? For reference, the track I go to has two points that I am most concerned about, both are 5-3 downshifts from 110+mph to about 50mph. |

You can do trail braking after gaining some more experience.

just keep practicing on the track. I think no matter how much u practice on the street you just have to keep trying on the track before you get used to it. The pace at which you shift on the track is totaly different and your mind should be distracted with all sorts of things like hitting the apex, your lines, brake zones, braking pressure, but youll get the hang of it over a day

Actually, I think it is much easier to heel-toe on the track. On the street, you never really press the brake pedal which makes it hard to blip the throttle enough.
On the track, you press the brake pedal a lot harder so the pedal is about even with the gas. I usually blip the throttle too much when I downshift. I think you would downshift in towards the middle of the braking zone. You have to scrub off some speed and lower the revs so you don't drop a gear and then mechanically overrev your engine.

Heel/toe on the track is like patting your head and rubbing your belly at the same time. Needless to say, I ain't got it mastered yet ...

If you can do it on the street, you can do it on the track.

Get a ride next time at the next event with an instructor and see when he/she blips the throttle in relation to the braking zone.
This is a post I made LONG long time ago to help people visualize the actual heel-toe maneuver and just about how quickly it happens: Quote:

I was used to the hinge at the top of the pedal on my old RX-7. Now with the hinge on the floor I'm all screwed up trying to heel toe.

Bingo. I learned heel-toe on the BMW where the hinge is on the bottom. So it's easier to do the alternative heel-toe where the heel never moves. On my WRX the gas pedal hinges on top. I've found that the Subaru is 100X easier to heel-toe the traditional way with the heel applying the blip despite my rather stiff ankle.
