i agree...
if you try to brake hard going into the corner...
ya might end up like the Megan Racing 350Z...
end up on top of a trash can and a tree

anyone got some sort of trouble doing heel-toe with VDC on?
I re-enabled VDC after many days disabling it... and it feels weird

The VDC will interfere if you're not smooth in your transitions...

well then i need to learn how to be a 'smooth operator' then
VDC kicks in and somehow cuts throttle...
then synchros kicks in or somethings?

VDC kills throttle because it senses an impending wheel lockup. The actual lock up might not have occured with out the VDC, we'll never know.

Try to drive "under" the VDC. Take the time to do your moves right. Speed is secondary and will come on it's own.

i dont speed, i drove 55 all the way back from Auto-X (seriously and thats without Cruise Control)
I just have ADD i need to move around like tap my foot while driving lol

I read all four pages and still don't get the point of the Heel-Toe downshift. What I don't get is how does it improve your control over the vehicle, or how does it improve your control, period? What benefits does it have over just downshifting with braking? Is it to get back into the throttle faster? I thought the point ws to slow down faster, why tap back into the gas, while working down into the lower gears?

its great for corner entry, you basically slow down for the corner, and while you are exiting the corner you are still at max, then when u exit the corner u shift up.
faster than leaving it in high gear

Ok, that's what I was missing. It's an exiting maneuver. I'll have to try it out. I'm usually fairly well back into the gas before I begin my turns, and throttle through them.

yeh u power through the turn in low gear so u max hp
then the second u exit, upshift

It's not an exit maneuver. Read my posts - I explained it crystal clear.

Yes, it allows you to exit turns faster, but the maneuver itself is performed BEFORE the turn. It's something that is done WHILE braking for the turn. It allows you to brake (to slow down) and downshift SIMULTANEOUSLY so you're always in the strongest gear possible for the turn.

That's as simple as it gets.

This is not a sequential gear box; it is manual with clutch; check it out!


of course, the type of transmission plays a big role, and it is not possible to do it exaclty that fast in the Z...now some cars, such as the S2000, it is possible to do it at that rate, b/c the S2000's transmission is unbelievably good.

Same here, lol... I'd need to get my foot through with a hammer and hacksaw .

Whathever works is good, what is important is the concept of braking/blipping downshifting. Practice and find the way you are most confortable with, you have succeeded when you seamlessly brake and downshift before a turn.

Good shoes help

Well done on the demonstration. That said when I first attempted to heal-toe I tried with this method and it didn't work out too well...my muscles in my ankle with the rotation couldn't produce the fine movment to match revs correctly (by the time my heal found the pedal i might as well have shifted normaly because there was no way I was going to get the reaction i needed). Now I know what you're all thinking - practice makes perfect. But after hearing and feeling the mis-match of gears over and over (shutters) you start thinking of different ways. Im a size 10 and basicaly all I do is keep my left half of my foot on the break and the right half over the gas. If I need to just break my foot rotates past the gas and engages the break - no blips or anything, and if you don't need to be ready, you can just break w/ your whole foot on it. However if i do need to "heal-toe" my other side of my foot is on the gas and i just *bilp (the left part of my foot determines how much break i need and the right part of my foot determines the throtle position for the gear) and do the same thing as was demostrated on the video. Its much quicker in my opinion. Btw if this is the same method as "rolling" (stated in the previous pages) my bad. I didn't know if there was an official title to this method ^^.

All I do is turn my heel out.... from this | | to this | \

It's natural feeling for me... it's nothing extreme. I do it slightly different than in the video. Rather than mashing the brakes dead on and twisting my foot almost horizontally, I hardly even move my foot. I hit the right half of the brake pedal with the ball of my foot and hit the gas with the other edge of my foot. It doesn't take much movement.

All you really need to know is what needs to be done. From there you can work out what is comfortable and what works for you.

The pedal setup in the Z is perfect IMO. Notice when the pedals aren't pushed the brake is taller than the gas. When you push on the brakes, right where you start getting pressure the pedals are even. They're also spaced just right.

The main benefits are for going around a tight corner fast.
You want to be in a low gear/high rpm to have the power through the turn and out of it. You want to avoid switching gears while in the turn to not upset the car when driven at the limit (track) and you actually want to apply the throttle before the apex.

So you have to get into e.g. 2nd gear before the turn while going fast e.g. 40mph on a 45mph street with a upcoming right turn (traffic light on green)
With this speed, if you were to just put 2nd in without rev matching, you would feel the engine braking strongly. It will upset the car if driven at the limit, and can cause the rear to spin as engine braking also upsets the braking bias, as it will only brake the rear tires.
So you need to revmatch. But how do you rev match with a blip on the throttle when you are actually braking hard shortly before the tight turn?
-> heel toe.
And the blip is not a contradiction to the braking, as you blip while the clutch is depressed, so the tires don't see your blip.

Basically on a very short distance before the turn you combine your braking with a rev-matched downshift which requires the blip when going fast.

the Z is great but it isnt 100% perfect - the S2000's pedals are el perfecto
try to sit in one and just place your foot on the pedals...
i did it last night at our mini meet - amazing

Like I said it's a matter of opinion. The pedals allow me to do what I need to do easily and comfortably, and that's all I ask for.

What would you change?

change the car from a Z33 to AP1 S2K?
