Ever since then, I have had a slight disdain for ABS. To tell you the truth, it might have just been that car, I do not know?

That explains a lot.
In 89 it would have had a quite primitive 3 channel set up, and there would have been quite pronouced pulsing of the brakes.
As an example, Iv watched an '90 Prelude with ABS doing stops during a driver training day at a race track. There was lots of noise, and the tyres were visable locking and unlocking prehaps 2-3 times a second.
The car didn't appear to brake as quickly as it could have, and a semi-proffesional race driver got the same impression you did. He could do it better.
He did several stops with the ABS on, then the fuse was pulled and he tried again. It took him several attempts to get close to the same distance, and on his final attempt bettered it by less than a meter.
He admitted that had it been wet he would have stood no chance of matching the ABS, and the ABS gave him much more control over the car.

As noted in that article you posted a link to, modern 4 channel systems are able to monitor and control wheel speeds 10 times a second, or faster.
On the same track day a new M3 showed up. It stopped with what I can only describe as smooth ferocity, all 4 wheels held at thier optimum traction limit for the hardest possible braking.

I'll buy that, so the older versions pretty much sucked.

I take it the R32 GTRs have 4 channels?

I gonestly don't know, you own one or two

I do know that at the time everyone else was only useing 3 channel systems, they were the limit of the technology.
However the GTR was some years ahead of other cars in terms of its on bourd electronics, and its quite possible it uses 4 channel ABS. Given the sophistication of the rest of the AWD system I would not be surprised.

heres another to attest to having ABS in the car as a good thing......my car was totaled 2 months ago because i decided to delete the ABS when i upgraded my brakes and threw on my new suspension. it was raining and a car cut between traffic and ended up in front of me, i slammed into the guy going 50 miles an hour while his car was at a dead stop. my brakes locked and i just slid into him.







EDIT: sorry! i didnt know the pics were so big on my host.
