A couple weeks ago in zilvia.net's offical unoffical chat on AIM, Tnord, me, and a couple others were talking about left food brakeing.
Well browsing around today I found some usefull information on left foot brakeing that I thought you all would like to see.

Have fun!

PS: show your friends how cool you are, LFB drift instead of e-brake <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt='

Edit: since basically everybody in chat now sucks i'll expand this topic...

The practicality of LFB in RWD cars, more specifically the 240sx. What situations do you feel LFB would be useful for us?

Besides letting you do really really cool burnouts???

From what I know, left foot braking allows you to stay on the throttle hard while either shifting weight to the front wheels using left foot braking or breaking traction on the front wheels while throttling through a corner.

I used to use it more for autox (but was never very good at it).  For track days, I never use it.  I don't feel smooth doing it, and that is the most important thing for me right now.  For me, it wastes too much concentration and I don't see the practical benefits, aside from that split second when I transition my right foot from B to G.

I was trying this thing in my escort and in my 240. On a 240 it didn't kinda work out too well. First of all since i got stock pedals it takes to long to drag my left foot across w/o hitting the clutch pedal. Plus, my guess would be that it's gonna be easier to press brake and gas pedals at the same time with your right foot and using left for the clutch.

On my escort though (since it's an auto my left foot never does anything) left foot braking in corners was alot of help. I dunnow exactly how it works, but i guess that with the brake and gas both depressed, i'm loosing traction in my rear and yet gaining in the corner by depressing gas in the front. So in rwd cars, it'll be backwards, cuz you'll be braking the front and rear and accelerating in the rear. So basicly u'll be getting understeer from front wheel loss of traction? <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>

Anyways, my Proof for fwd: Me in my escort and my friend in his 1990 accord race from time to time on these roads we got. I constantly beat him in the corners even though my car is higher, got worse suspension and is less powerfull. So when i told him what i was doing in the corners and he tried it, he started to beat me...

Well anyways, i'd say fwd cars gain alot by LFB but i see no use for it in rwd cars <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>

Well, I guess I didn't cover application.  My understanding is that it *can* be very helpful (w/ both rwd and fwd) at changing the car's attitude in a corner.  I guess the proper time is after turn in, but before apex?  Allows weight to be transferred forward w/o getting off the gas.  (maybe I'll look at those links now)

Honestly, since I've owned the 240, I haven't been autoxing where fast transitions make this a useful technique.  I find on the track that breating off the throttle does more than enough correction in most cases.  I only do that when I underestimated the turn.

2nd gear autoX courses.  since there's no shifting, well rarely, you can have your left foot on the brake pedal instead of the clutch pedal.  I honestly think it'd be good to "fine" tune your handling...like give you that extra .05  off your time or something.  I don't think it'd be a night and day thing...but if you have your handling down pretty good, and are looking to better yourself that much better...it'll be that much more of an edge on your competition.
