Once you've exceeded the limit of traction with the tyres, you're playing with the friction of the tyre sliding on the road surface... Not much...
At the end of the day, it all comes down to your contact patch on the road... If you've got no grip, you won't stop - simple as.
Heavy cars tend to stop quicker as the grip is superior, look at a Range Rover 5.0 Supercharged - same 0-60 as a Focus ST, HALF the 60-0.... That's down to weight and therefore grip...
Get some DECENT tyres on there, you won't do anything if you've got pizza cutters with budget tyres on... Even with Dunlop SP Sports I've never made my brakes fade on road on just 266 Lucas'....
ABS is simply a computer which continually monitors wheel speeds, if the brake pedal is pressed, it'll monitor the deceleration rate, if it starts decelerating "impossibly" fast as far as the computer is programmed, it'll simply release the brakes and re apply them to try and regain traction, usually ending in it simply locking again... Simple as - if you're cadence braking and you KNOW the limit of grip, there's NO way ABS will stop you faster... Try it - go out and at 50mph smash the brakes on, especially in the grease, you'll feel the car suddenly decelerate and then you'll feel the ABS kick in, it'll make loads of noise and you feel the braking force decrease... All 306 systems as far as I'm concerned are simply dangerous in the majority of instances - sub 50mph on the roads I generally drive on, I'd prefer to have it turned off... It simply releases the brakes too soon, it's tuned only to the OEM tyres and braking system - of course, ABS works best when it reacts as SOON as the wheel starts "locking" decelerating impossibly fast - there's been NUMEROUS advances in tyre technology from 1998 to 2012.... That's 14 years of development in tyre technology, todays tyres don't reach their limit of grip anywhere near as quickly as P6000s did - P6000s were out in the early ninties... The only thing ABS does for you is give you steering, but in the VAST majority of cases where I've needed to stop fast, I just need to stop... There's nowhere you can go, I'd rather have those few extra feet.... It works well in a Motorway environment if people start stopping very quickly, you can swerve into the next lane whilst as hard on the brakes as is possible, but 99% of the time, there's someone else there, you've not got time to swerve whilst on the brakes...
That's my opinion on it all...
