Brakes
Does anyone know if there are locost's out there with ABS brakes? or is this the stupidest idea you heard in years?

Not sure of locost's but there are a couple of DAX rush's with ABS fitted ( not sure if they are on the road ect )

ABS is great and I'd happly have it on my seven. The problem is tuning it. Your donor car is unlikely to have the same weight distribution,
the same dive under braking or the same body roll as the seven. You may also want your ABS to be more or less intrusive than your donor and more or
less progressive in applying / releaseing the ABS action.
Sevens have better balance, poise and grip in the dry than an ordinary car and so would neel ABS less, though I can still lock up the wheels if I try.
In the wet, it is a different story.
That said, ABS only activates if 1 or more wheels is slowing faster than the others and is about to lock up. In normal braking, ABS does nothing and
so is not a problem. Only when braking beyond the tyre's grip does it activate and if you're in this zone, any ABS may be better than
none. The most braking effect is done when the tyres are just slipping. A badly tuned ABS may cut in too soon or too late to give the best effect.
In a death slide, even under effective ABS would help.
Most ABS units these days expect a CAN bus to be presen and may object is one were not connected.
The clincher is that ABS units are heavy and most people would rather save the weight.

In my experience, on the road, the ABS on my car only operates in the snow and then it took the car twice as far to stop, scared the poo out of
me.

I have a strong dislike of ABS as well!!!!
My road car (XR4x4 sierra) has it, and it's not too bad as it is pretty "insensitive".
I drove a Renault Megane with ABS and it is a hazard in my opinion. It modulated the braking under dry conditions braking fairly hard for corners, to
the point where it undermined my confidence to push completely, totally ruining any driving fun.
On the sierra, the one big hazard is if you hit a pothole while braking for a corner. The jolt momentarily locks the wheel, and the ABS seems to have
a "default" modulation period, which seriously eats into your braking distance.............ok when you plan for it but an off road
excursion the first time it happens.
Basically, abs is marvellous for people who cannot drive and who's first reaction in a panic situation is to stamp on the brake. For anybody
with at least some capability, it is not a good addition!
PS I can drive reasonably well, and therefore can feel when I am braking to the locking point on a car, so please don't suggest that the abs was
"right" on the renault, there was a huge margin of braking still available before full lockup set in! Most cars with std slightly worn
dampers will jitter and slightly lock odd wheels whan braking hard, normally this is no problem, but abs makes it a problem.

A motor engineer (i.e. a man who designs cars) once patiently explained to me that ABS does not make you stop quicker, and can often increase your
stopping distance.
However, what it does do is allow you to maintain control and steer around hazards in slippery conditions, such as when you're doing an
emergency stop and trying to avoid something.
There have been occasions in the past month or so when ABS would have improved my sense of well-being, as I experienced "moments" on the
slippery roads...

ABS can modulate each wheel separatley, whereas a foot is all wheels or nothing. ABS operates far faster than the foot can. ABS has no fear and
operates just as well with a calm driver as with one who is panicing. Few people have the kind of car control that can out perform ABS, especially
when you have to steer as well as brake. I'd rather have it on my road car than not. By the way, I used to design machines to test ABS / EPS.
I have a fair understanding of how they work. The vast majority of people are better off with it.

I've also run the Renault Megane and (sorry for the poeple who have one) the ABS is very bad on that car... As a daily drive I have a audi A3
that i run to the limit somethimes and the ABS never kicks in on dry roads.
You are wright, you better have no ABS if it is poorly designed or tuned for the car.
