300bhp. You appear to argue against yourself. In one breath you state that the weight of the wheel gives tration, then you state that same wheel held onto the chassis by a retained spring would not help stop it rolling over.
I had to laugh at your comments stating that if a British manufacturer claims something, then it must be true cause they don't lie
A well set up suspension will work wonders. I see excellent setups regularly. One of the best I have seen was on this years OBC winner. These are US products like king springs.
What I see on many of the trucks with dislocation cones are poor setups. As stated previously, they put stiff springs on with little movement ans then wack on cones. Also they only get the back of the truck to move with the 3 point suspension. With their stiff springs they cannot get the front to move. So in most of the photos posted on this thread and others, the trucks a leaning with the front suspension. This is not a stable or well setup truck. Cones can have there place. I have said that I am looking at putting them on mine. But not in the context of this thread.
Mostly they are a wank factor put by people who don't know wat they are doing. But everone goes oooh aaah, doesn't that look cool. I have seen a lot of vehicles with those angle indicators, roof racks, chinese winches, and hiclones. Doesn't make them a good idea.
