maybe it's for drag racing...
when i do a burnout, hitting speed limiter starting to roll off to start line tap brakes "oh crap" abs thinks i'm trying to stop from 180kph... me = looking like a dumbass and car halted to screeching stop

was embarassing

LOL, but i've learnt to be a bit more gentle on the brakes but ya had to be very gentle hehe

I guess he has four feet and four brake pedals in his car so he can modulate each wheel like ABS ( yeah I know, we only have a three channel system).

well

do what I am doing.. retrofit with four channel ABS!! ;)

Lighter than the old, FASTER and that how you can install yaw stability in the car too!!

God I love technology!! ;)

I've done this very thing, cutting power to the ABS computer with a switch (basically the same as pulling the ABS fuse). Just a quick note: If you flip the switch to turn off ABS while driving, and then later want to turn it back on, the abs system will still be off. You'll have to cycle the ignition on/off before the ABS comes back online.

ABS is also importent when swerving and braking. I dont care how good of a driver you are, ABS will still help you in that situation.

yep, ABS is more of a stability system than anything (love the marketing hype on the newer systems that do the same thing our old one does)

if you lock a wheel up, it will cyclee the brakes there. works really well when some bastard toad jumps out in front of your car in the rain and you have to brake and swerve.

I can see TESTING without ABS, but I like mine...

wether or not said individual can outstop the ABS system is undetermined. May I suggest a big brake upgrade:love:
Actually, it was determined a long time ago. Since no human can pump a break pedal 10-15 times in one second, you are not as faster as the actuator. Quit thinking you are. As in anybody that thinks they can outperform it.

Braking distance isn't even the primary function. It allows you to steer in a panic stop. The fact that the car stops much shorter is a icing on the cake.

I am sure somebody has rigged a test to make it look like they can outperform ABS somewhere.

Another key point is that a driver cannot modulate the braking of an individual wheel like ABS can. No matter how good you think you are, you only have one brake pedal to play with so when one wheel slips, you have to reduce braking across the board, even when the other wheels are not slipping.

If this is a daily driven car, I don't think it would be wise. Doing this may indanger yourself and more importantly OTHERS.

I guess it depends on your definition of "out perform." No human can cycle a brake pedal 10-15 times in a second. But that isn't where the human vs ABS debate has merit.


ABS pros:

*Any idiot can stomp on the brakes and stop near optimally on smooth flat ground.
*Any idiot can stomp on the brakes and still turn the car.
*Any idiot can stop better than a pro on uneven road surfaces

ABS cons:

*A pro driver on r-compound tires on smooth, flat ground can match or beat an early ABS-equipped model (but probably not in every attempt).
*You can't lock-up the brakes. (why would you want to, you ask? One example is if you were losing control of the car mid-corner with an obstacle on the inside. With ABS, as you spin the car will rotate into the turn -- you basically have no control and are along for the ride. But if you could lock up the brakes, you would continue to go in whatever trejectory you were last in -- meaning you slide to the outside of the corner and away from the obstacle)
*Some ABS computers get finicky with staggered wheel sizing
*sub-par braking with fading brakes (the system may be able to cycle 10-15 times per second, but when the pads don't initially bite, it does not matter)
*you can't (easily) adjust the cars balance by braking mid-corner (almost all ABS cars will understeer mid-turn)


So for the average joe, keep your ABS. For those who have a good reason to remove it, remove it.

Um, I didn't get the impression that hes was trying to remove it, just add a switch that allows disabling when desired, as well as the fact that it's supposedly going to be a rally car. Maybe someone can tell me- Do race cars-aka- NASCAR, CART, Formula 1- use ABS? I've never heard.

PS- Figgie- what's involved in switching to a 4 channel system??

ABS is to prevent wheel lockup during hard braking, specifically on turns. It isn't for racing, it just helps almost every driver.

ummmm... rally cars run ABS (ever seen the super advanced stuff the Evo's are running?)

if you need to cut a corner, pull the e-brake or use your right foot...
