The problem is that some modern cars need ABS because it is an integral piece to their braking system. The example I can think of is the Corvette. GM has designed their cars around the ABS module and is a key piece to controlling brake proportioning.
Technically correct, but you make it sound moreessential than it is. If you want to remove ABS, it's no harder than removing the compon3ents, re-plumbing the hard lines , installing a proportioning valve and PERHAPS adjusting the pad compounds front-to-rear to geta F/R bias split that you like. You end up doing that on any race car any way.
The factory brake system needs the ABS and will not work properly without it. The system is so over boosted that it is hard to modulate the brakes. Corvettes that lose ABS are practically guaranteed to flat spot their tires.
I've driven C5 and Corvettes with disabled ABS. It wasn't difficult at all to threshold brake.
I can't think of too many cars that can out stop a Corvette. But in all honesty, racing isn't just about speed. Consistency is as important if not more so.
Do you race, or run open track? The vast majority of passes are made under braking. You HAVE to get the maximum out of your brake system under those circumstances to out-brake the other guy.
You can lap within 0.001 seconds of your best lap time, but if you can't out-brake the guy in front of you, you'll have a much harder time passing him.
In a Mustang, ABS isn't necessary. But if you are threshold braking, it shouldn't be kicking in anyhow.
Depends on the tuning of the system. Most ABS systems (including the Bosch units, which are considered some of the best in the industry,) are pretty conservatively tuned, probably for liability reasons. Threshold braking often will be defeated by an over-egar ABS system kicking in before the tires really have locked up.
It you're threshold braking and not kicking in ABS, then you're being too conservative, or your ABS setup is DAMNED good (which I doubt.)
But if you exceed that threshold, then the system will at least save your tires some wear and tear. And if you are running in the rain, I would bet the ABS will be worth its weight then.
It is nice in the rain, but not as critical, since speeds are so much reduced. Threshold braking in the rain isn't all that hard, so the need for ABS is reduced, plus the fact that it's almost impossible to flat-spot a tire on a wet track.
An interesting bit of observation I have seen over time is the braking distance of the Viper. The cars were initially released with out any nannies like ABS. In all the media tests that were performed, they could never get the car to stop like some of the other cars with ABS. As soon as the Viper was introduced with ABS, their stopping distances were finally comparable to other cars in their performance bracket.
MEDIA tests? Please. Early Vipers had a whole raft of tuning problems in the suspension and the brakes, which most media writers either didn't know about, understand, or write about for fear of confusing their readers.
I'm going on personal observations I've made in a variety of cars on the track as an instructor. Generally speaking, I can threshold brake better than most ABS modeules will let me. Cheap GM and Volkswagen systems seem to be the worst. The Corvette's ABS is pretty decent. The Porsche ABS is tuned very, very well, but they all interfere when turned on.
ABS encourages bad habits and rewards a lack of control and finesse at the brake pedal. Simply stand on the pedal and let ABS to the controlling.
