the red E46 was a M3 i'm talking about with the DSC turn off.... 
and i'm not driving a M3 ...try using a M3 or any bimmer to drive like what i did...u will crash or makan gravel..
for the GT3 driver he runs wide all the time because of lifting the throttle while turn in at mid/high speed........he's not that good :lol: ...left foot braking is the answer.....u cant lift the throttle while going thru turns at mid and high speed in the porsche like GT2/GT3 or older model without psm or4WD....with 4WD or PSM thats a different story....
for me the tricky turns in sepang r 9..14...15..i'm not a good driver is the car..heheh
:blush:
oh ya..in sepang all the PRO/good drivers shift the tranny 22-23 times per lap.if i'm not wrong
here is another video me chasing 360 CS...at the end all tapau by GT3 MK1.....thats JP chin btw...old dude somemore... :blush: but practice make perfect....see..a gt3 with good driver...i cant smell the exhaust fumes also..heheh

Just curious what car were you driving around Sepang then? Must have put a few blushes to the faces of the Porsche and Ferrari drivers

I thinks its a Honda Civic...
ls1, how would left foot braking help a RR car like a porsche? wouldnt a sudden shift of weight to the front (like a throttle lift or lfb) cause the rear to pendulum?
or are u talking about lfb before turn-in to stay on the revs and still slow the car enuff to take the corner while on throttle?
just curious.

I assume left foot braking would actually reduce the effect of weight shift cos u don't lift off the gas pedal to step on the brake. My guess...Originally posted by Redd@Feb 12 2006, 12:00 PM

I'm only good in theory... I could never master LFB...as my left foot is always too clumsy. Took me many months before I got heel and toe working (learned through Best Motoring videos lol)

A severe problem affecting most front-drivers is understeer during fast cornering. Understeer generally means that during cornering at a high speed, the car has a tendency to keep moving straight and to the outer edge of the curving road rather than the direction in which you are pointing the car. To cancel out understeer, there should be more grip at the front wheels than at the rear. The left-foot braking technique more or less helps you to do just that.
When approaching a corner, you should start slowing down like you normally do, using your right foot to apply the brake. At this point, you can use the heel-and-toe maneuver and downshift to the proper gear. Now, you should move your right foot over to the accelerator and your left foot to the brake at the same time. You are now ready to perform left-foot braking. Continue slowing the car down to a reasonable - but not too low - speed by applying the brakes with your left foot. As you are about to turn into the corner, hit the gas with your right foot and keep braking with your left foot at the same time. Being a front-wheel-drive, the rear wheels will lock while the front wheels keep moving. The car's weight is transferred to the front, causing the front wheels to have more grip than the rear wheels. The car now starts to oversteer.
Now you have to keep the car in control by steering in the direction that you want to go, and applying more or less throttle and braking as needed. You have to use both your pedals at the same time, which will take practice. Lifting off the accelerator will cause more oversteer and flip out the car's rear even more. Applying more throttle while easing off the brakes will reduce oversteer and straighten out the car. Keep performing this balancing act to smoothly clear the corner at high speed, all the while making little corrections to your steering. At the end of the corner, just floor it and power out.
When you get good at this technique, you should be able to just keep the accelerator completely floored and keep the car moving in your preffered direction using just your brake pedal and steering wheel. Understeer is eliminated if done correctly and you clear the corner at a higher speed than in normal driving. The trick is to keep practicing braking with the left foot and learn to apply the brakes as well with the left foot as with the right.
With a typical race-car gearbox, you can even start your initial braking with your left foot instead of your right without having to use the clutch pedal. When braking, you can blip the throttle between the gear change. Most normal gearboxes cannot cope with such abuse and so it is generally better not to even think about trying such a move with your commuter car unless you have deep pockets to foot the resulting repair bill! Also keep in mind that many upmarket cars are equipped with computer-controlled stability systems that will help you to safely keep a car in control during high speed cornering. But with practice, you can control a car better with the stability system turned off and turn at an even higher speed.

let me try it out at thje track tomorrow. Would be interesting in a porsche that is rear heavy. One thing we must understand is thecharacteristic of a Porsche.
not driving a toyota or honda.......a stock evo 8 MR..company's car ....
the best for sepang..it's still Honda DC5.....with just light mod..can go very fast already............
on a RR layout porsche without stability control system or 4wd...lifting the throttle on mid/high speed turns..your car will slide off the racing line or running wide...to keep the car on the racing line u need to apply the left foot braking while keep your right foot on the gas..to stay on the racing line....it's just a human manually control stability system....
the car wouldnt flip the tail with throttle lift or left foot braking...when u do it correctly....

You need to do that whilst in a straight line. What that does is to transfer the weight to the front of the 911, hence endowing it with sufficient grip over the front tyres to turn in without understeer. This is all done smoothy and in theory, of course!Originally posted by Redd@Feb 11 2006, 11:00 PM

(and on the exit, as the turn opens out, you mash the throttle, sending power/weight rearwards and exploit the rear biased weight distribution as you rocket outta the corner!)

It's a very late apex, that's all. Simple.
