I wouldn't use left foot braking in the S.

As said above, it is definitely a FWD technique and I wouldn't want to be shifting weight like that mid turn in the S.

LFB is for traction issues such as losing the front tires in a turn: applying gas and brakes regains control of the front of the car and gets the traction back without hurting momentum drastically or watching the car drive itself out of control.

 

Left foot braking is stupid and unless you're driving a WRC car, totally unnecessary. Everybody has seen vehicles accelerate from a stop with the brake lights still on Those are the same people who complain that they go through a set of brakes every 20k mi.

 

It is a great idea for track driving when you don't need to downshift entering a particular corner. I use it all the time in my Miata and 300ZXTT when I'm on the track. It allows you to maximize your speed without jumping your right foot back and forth. I don't ever apply both pedals at once, I do it to eliminate the transition time from brake to throttle. Again, this is only in the "esses" where downshifting is not needed.

The BMI vids also show LFB in AWD and RWD cars in the situation I described above. It is also used on the straights (a slight dab) to ensure the brake pads are positioned against the rotors. The pads may be pushed away a bit on long straights and would require more pedal travel if this technique is not used. Again, only for track use.

I LFB on the street occasionally to keep up the dexterity of my left foot.

 

whoa... a lot of random responses... I was referring for track use...RobZ nailed what I was trying to get to... I'm sure LBF wears the hell out of the pads, but are there any other negative affects?

I guess its more of a turbo thing with LFB... keeping the throttle open with a little bit of LFB prevents turbo lag during transitions... WRC drivers practice this all the time. I remember when Hans Stuck took the titles for Audi, he mentioned that LFB was what allowed him to win the races. I was curious if anyone did it to maintain Vtec without lifting the throttle. That does sound a bit dangerous for RWD...

Still curious though, does the '06 DBW cut the throttle when attempting LFB?

I go typically go through a set of OEM pads through sheer high spirited late night/early morning canyon/country runs in about 8k miles.

I dun't left foot brake.



And I'm not complaining

 

Not all professional racing drivers left foot brake.

 

Left foot braking allows you to transfer weight to the front of the car to plant the front tires. This counteracts understeer conditions while on the gas.

 

Almost every F1 driver left foot brakes. I think Rubens might be one of the only exceptions.

If you are driving a sequential transmission race car, there is no reason not to. Trail braking, cleaning the pads, drying the pads, quicker transitions in general...so many advantages.

 

Left Froot braking is used on FWD and AWD cars (particularly at the track) to INDUCE oversteer. Doing it on a car that is already PRONE to oversteer is a recipe for a spin.

Keep your left foot where it belongs 99% of the time on the track, on the dead pedal.
