UH, ABS is Bad... Why? cuz it's making driver inputs for you when you may not want it too. You only want to remove it if your an experienced driver that will drive competitively.
Here's an example:
Your drifting through a corner nicely and it's time to mash the brakes real quick for a weight transition because a turn in the other direction is near. With ABS: your car will flicker the brakes and try to stop with all the traction to the ground; no slippage. Without ABS you smash the brakes and the front end locks up, car's nose dives, and you flick wheel whilst letting off brake;smooth.
ESPECIALLY while trying to manauever your car an any type of slick road conditions like gravel or mud! Your ABS will think all the car is skidding on pavement when in reality your skimming the gravel in need of 'lockup' to bite down to the surface under the gravel that supplies your traction.
Snow is the only exception because it is so slipperey and brake lockup can be your enemy.
I had to disable my ABS in my STi before every race because of my driving style. If you drive much like you do to go to work all the time, then keep your ABS! For the sake of other drivers. because most likely your brain will tell you to slam the brakes and you will lock up all 4 wheels and go into a nasty slide... Gladly, society has become dependent it. Sadly, race enthusiasts are still using it...
-if you have never driven a car w/o ABS and you disable yours, LEARN CAREFULLY
