Abs
A quote from an article that dispels one of the myths about ABS...
Know this about antilock brakes - CNN.com
Many people believe ABS allows them to stop quicker than non-ABS. It does not, or at least not by any significant measure. All ABS does is allow you to slam on the brakes while turning the wheels without spinning out.
So don't go driving like an idiot just because you have a nanny like ABS.
No need to read the entire article as there wasn't much else in it of any real importance.
• Maintain the same safe stopping distance from the vehicle ahead as with conventional brakes. ABS will not make the vehicle "stop on a dime."

I happily do not have a nanny system for my braking situations
Nice find because I don't understand why anyone with ABS would think that they could stop on a dime.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
– the late Tom Thrash SCCA Solo E Production
the only reason it helps you "stop faster" is because most idiots lock up there brakes and just let the car skid to a stop in which case a car with abs will stop faster.. Now if you have half a brain and dont jsut mash the brakes to the floor and hold it there, then I can for sure see how there equal in stopping distance
what is this ABS you talk of?

lol, ABS only helps if you dont know how to brake, i have to admit, it would of helped me when i was 15 once driving my old miata.
But is it true that if you have ABS, and its not working currect, Example, ABS check light is on, the cars stoping ability is in danger, true? or you'll just be running the car like if it was non ABS
Ether way, i think ABS is usefull, in a suddent situation, where you you have to stop, and your scared and your mind goes blank, first thing you do is slam on the brake!
not everyone is a race car driver.

ABS helps just about anyone stop faster.
It prevents the wheels from locking up and skidding, which is too easy to do. If you ever see a graph of braking force vs. pedal pressure of ABS vs. non-ABS cars, they both have a rising rate up to a peak. The ABS-equipped car will peak have a small spike, then drop to a value of about 90% of that, at which it will plateau, no matter how much pedal pressure is applied. The non-ABS car will peak at the same spike, then see a drastic plummet as more pedal pressure is applied, since the wheels begin skidding at that peak. The ABS car senses the wheels just starting to slip at that peak, which initiates force suppression.
So theoretically, if you've got the JDM Stage 6 driver mod and all achievements unlocked, you could "plateau" your braking curve at a point higher than 90% of the absolute limit, in that small (tiny) window between ABS braking at the maximum limit of adhesion. Now until I personally datalog braking force before and after and ABS install, with all other things being equal, I'm going to assume pretty much nobody is going to be able to have such precise brake throttling (oxy moron, I know) to constantly hold braking pressure above that ABS plateau.
Another thing is consistency. I would think it would be much easier to control a car that is undergoing constant braking force, rather than teetering near the limits as the driver is trying to hold his foot steady, or increase/decrease pedal pressure smoothly. On top of that, it would be much easier to control the car when you can simply plant your left foot (or right toe, pro), and focus on the gas, clutch, steering, other cars, pedestrians, gunfire, road head, whatever. Here's another consistency factor: get a little overzealous or panicky just once and you could flat-spot the tires enough to put a damper on all performance aspects.
On top of this, I can only imagine where ABS systems have gone since I've become familiar with this basic advantage. Improved sensors, dedicated control units, better valving, etc.

Individual wheel braking. A computerized ABS system can monitor all four wheels and detect when one locks up, reducing brake torque at that wheel, then reapplying it when it detects that the tire has regained traction. It's physically impossible to do that manually with only one brake pedal, no matter how much of a driving god you are.
I'm not a huge fan of computerized driving aids for track use because they make me question whether it's driver skill or the software that's getting me around the track. Still, you cannot deny that ABS, traction control, stability control, electronic torque distribution and other technologies are sufficiently advanced that they are a safety advantage, and when properly setup in performance cars, a performance advantage.

Yea, ABS fails. Not having ABS for the win. Nannies suck. Id much rather know how to brake properly than have to rely on ABS. ABS is only for morons that just stand on the brake pedal and pray in an emergency. They deserve to hit stuff.

You're so hardcore and impressive. I bet you don't have nannies like power steering, power brakes, power windows, or headlights, either?
