Yeah, you can't outbrake ABS, but you can never properly load up the front tires (weight transfer). With ABS the load on the front tires is dissipated. Thus, on the turn-in you can never get the rear-transfer to catapult you out of the corner. IMO.

Makes sense in theory but I haven't found this to be the case in practice.

There is a fuse you can yank out. Fuse 5 located under-dash driver's side (7.5A). i've never did this b4...so I don't know if pulling this fuse will disable other componets as well??

Or you could try unplugging the ABS contorl unit (its 1 piece with the ABS modulator) located underneath the hood in front of the brake master cyclinder. Again I'm not sure of any consequences of doing this?

I find that the ABS kicks in a little too early. The same thing happened in the Integra Type R. I would assume its the same system. You can especially notice this when you dive hard into a turn and there is a slight bump..ie if the road surface is not exactly even. I wonder if this is the same for other ABS units found in similarly quick cars from other manufactures?

There's one corner at one track where I consistantly kick in ABS every lap. I've talked to other drivers of faster ABS equipped cars and they've had the same experience.

None of us found ourselves braking espeically hard for that corner, but perhaps the uneven surface or uneven grip (concrete corner patch) may have been the issue.

I've also seen a lot of cars without ABS go straight off that corner, so IMHO, ABS is a good thing.

In my experience, the use of r-compound tires almost completely removes the likelihood of ABS engaging. This is further enhanced by using the proper brake pads. I found that the Carbotech P+ and the Carbotech XP, imbues you with the ability to properly modulate the brake pedal. However, I am very thankful that I've got ABS and have no plans to disengage it. As Mikey said, "it's a good thing." When I was still using S02s, I can remember numerous instances that ABS saved my behind coming in too hot into a corner and furthermore, having the ability to steer while braking.

I must add though the harder you brake the braking zones become more treacherous. The car will steer as the suspension toes-out and furthermore, heavy braking zones will have troughs that where not there before. Gotta find a slightly differently line. Recently, I was taken for a ride around Summit Point in a Caterham Lotus 7, by the owner of the driving school. It was quite an eye opening experience! In that order.

watch the Best Video where they compare a Subaru with and without ABS, the difference is ***king unbelievable - you would never not want it. I had chance to sit as a passenger to a professional driver in a Carrera in an auto-x- he constantly was on the ABS - even I could hear it pumping away.

Errrr...

Actually, you can definitively outbrake ABS. In my job I test braking systems as well and one part of it is to determine the effectiveness of the ABS system. This has to be at least 75% of the maximum performance (when you brake on the slip-limit).

We test this with a rotation speed measuring device on each wheel so you can determine if the wheels actually locked up through the ABS system or not. Additionally we have a bunch of decelleration equipment on board with fifth wheel or correvit device (light beam on road surface) to determine accurate speed of the vehicle.

Effectiveness of performance is typically 85-90% (!!!)

ABS is specifically usefull for so-called split friction road surfaces (puddle of water or wet leaves on side of the road) and of-course to keep steering ability for regular drivers when they have to perform an emergency braking action (I don't mean the parking brake obviously )

Just my two cents!!

Isn't that also a function of how the ABS is programmed? Have you tested the S2000? If not, you have a perfect opportunity to see how this one performs!
