The workaround requires you to disable your brake pedal electronics, which will also disable your ABS. So if you are OK to run sans ABS, then go for it. :)

Will you be faster if you can left foot brake on the 370Z? The answer to this question is not clear. Some pros left foot it, but the majority do not. So I don't think left foot braking is needed to extract the most from the 370Z.

Yup. It's very much a personal preference otherwise all pro drivers would be using the same technique.

I'm pretty sure my track days won't go any 'better' if I get another 0.1s faster lap with left foot braking :). Seems like timing the laps would be a more fruitful place to start to improve my lap times!

Just played around with left foot braking on the way back from work. Too bad our cars cut throttle 75-80% when you hit the brake. Definitely can't accelerate out of any corners while braking to distribute torque like in the videos.

i know for the 350z all you had to do was pull a fuse from the kickplate box. brake lights. or obviously wire a switch up to it if thats something you did regularly.
but no i have never even attempted for any reason to LFB myself, but i dont really track either

On the Base model I think you disablesrhw brake lights. But on the vdc cars you had to kill power to the abs/vdc module. This was done for drag racing purposes where having abs or brake lights isn't all that critical.

Not sure they're crucial for the road either...oh wait.

I guess I'll just keep working on my left foot clutching :)

If this can be disabled with pulling a fuse, that's a BIG plus for me! I'll have to check into it more...

As an autoxer, I learned LFB several years back...over a winter of constantly doing so....and its now second nature on the course, although I do have to think about it when getting into a corner where a down shift is needed, which isn't very often...

But, there are definitely advantages to doing so in autox...where you can stay on the gas and use the brake to trail brake into a corner, settle the car in slaloms, scrub just a bit of speed without lifting, etc....

pulling a fuse for ABS is legal in class! :tup:

Factory ABS actually leaves about 10-20% of braking potential on the table, so with some practice you should be able to go even faster without ABS. Just some more food for thought.

This is a great thread. :)

You need to buy a spare fuse module (it's a 3-in-1 fuse) so that you can cut the fuse for the ABS without pulling the whole module. If you pull the whole module you will disable VVEL and won't be able to rev above 3000 rpm!

It's been proven that brakes wear faster with that technique 'cause drivers unconsciously tend to rest the left foot on the brake pedal even when not trying to brake.
