left foot braking transitions

What I'm basically implying is that if you have to do an emergency stop, just use your right foot if you don't want a high chance of fuckin up because you slipped off the brake pedal because you have both feet on it.

which is why i have to rotate them 45... so they dont slip off... which is why i'm asking about a wider pedal... LFB gains you a huge amount of time... when going from gas->brake... you dont have to pick up and move your foot over and then apply brake... you just start applying brake.

i start with the left foot. and as the revs get down at some point i need to downshift. so while im still braking i change which foot i'm using which means both feet need to be on the pedal at one point, then i can use the clutch and heel-toe to get the throttle blip

Not sure panic imma-hit-somethin-hard braking is the time to be concerned about how quickly you get back up to speed.

But, instead of all of that feet confusion, why not just learn how to downshift without the clutch? If your heel/toe is that good, you can't be far off from being able to do it without moving your left foot.

I do find it odd that you're presenting a dire must-stop-nao scenario with a strong interest in how you'll get back to speed before you've even successfully avoided whatever the emergency was.

That's a good point. Could just pop it in neutral in that situation. I can shift without the clutch just fine on a dog box like a motorcycle but i donno... i guess i don't trust synchro manuals? What about the other situation I was talking about? If you can manage a smooth foot transition on the brake, why not LFB for every corner? Even corners where you need to downshift?

I don't think so, I never really thought about it.

If you have a Moto-east (Ecutek) tune, it has blip throttle downshift.

OP - Why do you think you need to all of the sudden LFB?

Don't need it. Prefer it though. Do it all the time now... foot just stays there and goes to use the clutch when I need it. I can do the transition from lfb to rfb with the pedal down just fine without fucking up the brake pressure, but turning my leg so far to the side is kinda annoying. it would be easier with a wider pedal and I figured other people would have figured out a better pedal setup already...

This is not really true, it may feel like it is however...Most people that lfb end up braking when it is not needed, too often, or even dragging brakes (in my personal attempts as well).

Go listen to some podcasts at http://autocrosstalk.com and hear what all the top autox drivers in the country think about it. Most all of them say LFB is not faster and don't bother learning to switch if you already RFB. In the end it's your preference, but I don't think there is any benefit unless you really really master it. Even then, the benefit is so minimal it's likely a wash.

i'm not talking about lap time. i mean time from the point where you start trying to brake, to the point where you are actually braking. that doesn't have hardly any impact on laptime until you're at insane times i understand. but in traffic, having that extra few ms might help.

You should know where your braking points are ahead of time, get your eyes up and look for them. You shouldn't be reacting, your inputs should be planned.

If you can't brake hard enough with just your left foot, there is something physically wrong with you. I have confidence that you can get into ABS with just your left foot, there is no reason to have both feet on the brake pedal.

Left foot braking is a technique that helps rotate cars that have less than ideal balance, like many awd or fwd cars. It is also helpful in rally or low grip situations where you have to use weight transfer to accommodate low grip.

Brush braking, trail braking, and left foot braking are of limited use in a twin. Stop using so much brake and just lift to transfer weight, you'll go faster.

Brakes only slow you down.

My bad, thought this was the tracking / autocross forum.

Personally I would be trying avoid putting 2 feet on the same pedal, but that's just me. Hope you find a solution to your problem.
