There's some good info here... I've been teaching myself LFB in the past couple of days and it really is an amazing technique, especially for FWD cars that understeer entirely more than desired (like the RA). If you're about to learn the technique, I suggest finding a long stretch of parking lot or empty road in which you won't have to focus on traffic or objects, that way you can put most of your attention on pedal placement and sensitivity of your left foot. For your first few attempts to LFB in a straight line (just for accustomization) it might be a good idea to rev it up to more than cruising RPM (maybe 3k or 4k) in case you brake harder than intended and have to suddenly switch to clutch in order to not kill the engine.
Last night I found a parking lot with enough space to practice and one nice sweeping turn. Though it was really wet and not very uneven, I was able to get a good sense of LFB in my car. I kept the car in a constant LFB almost drift-like state for several rotations around some objects and my left foot was on the brakes for at least 10 minutes in total. Once I parked I thought of checking how hot the brakes were so being the dumbass I am I just dabbed the front disc with my thumb not really taking any precautions. They were so hot that I still have a big patch of discolored skin right now! Yeah so don't touch your brakes after LFB for a long time, but I guess everybody here cept me would think of something like that
.
From what I've learned (in the car), it's all about giving it enough pressure to keep the back end as loose as you want it, but without lowering the vehicle speed lower than you want. I'm sure this practice in an N/A car will help for once I get a turboed car (hopefully) sometime in the future.
Just one question: when using LFB to balance suspension state through a constant-radius corner, would you guys normally make slight ongoing adjustments to brake pressure, or just mainly with gas and steering? I know that I use every control to adjust the car, but how do you guys do it?
