Hi,
Looking at a 92 Range Rover that a guy has spent $12,000 on a 4.8 ltr 'stroker' engine, reco transmission and this 'active suspension' which l'd never heard of. He says it keeps the vehicle flat with little body roll while on the bitumen, and doesn't affect at all off road work. Normally this balance is impossible - or is it? Anyone with any experience of these systems? thanks

Take a look a the Disco 3 with active suspension. I gave the steering wheel several very fast hard turns left and right and left and right at 70 k per hour, the suspension kept the body flat and whats more the brakes were applied (it seemed to individual wheels) stopping the car despite my foot being firmly applied to the accelerator. Yep it is available and it works.

PS there is some trade off with respect to off-road performance. In the older Rangie, probably noteceable but since it would be pretty good off-road anyway no real concern. On the Disco there is some loss of articulation, partly made up by the high tech traction control etc.

Yes it is, although again he doesn't know much about it, put it on because it was his wifes car and she complained about the 'body roll' around town. Some mmob in Sydney did the work called John Davies motorsports or something. Thanks for your help

lestraw, It is made by a mob in Moe Victoria, now bankrupt, it works by using the power streering pump to apply pressure to each end of the sway bars as required to keep the car level. It gets feed back from a smallish box with a pendulum fitted in the engine bay. Very clever system. Make sure your power steering fluid is kept clean. Doesn't seem to effect offroad ability at all. I have driven a 80 series demo, 44" tyres, before and after fitting with the system and the difference was amazing. If you need any more info, I may be able to track down the patent holder.

Sounds like the system, drove the vehicle today and it was awesome, handled like a go-cart, pity the rest of the vehicle was a mess. Nice and simple design, no electronics so bit of a shame really. The owner spent $12,000 on the system and a reco 'stroked' 4.8 litre, only 2 years ago - wish he had of put it in a decent body - anyway will keep looking
