| Cowboy lift? Is it possible? |
|
Just wondering if anyone has tried to use the suspension calibration to give their disco a lift.
If my logic is right, kits like ez-lift do it in this way, and just adapt the suspension settings on the fly.
The 2” lift kits trick the suspension into sitting a different height.
What’s to stop you setting the calibration to be say 2cm higher than it should be, giving a slight lift to clear bigger tyres?
Or have a missed something a likely to cause an issue? Disco 4 2012 HSE, Nara Bronze

if you got gap tool you can set you default height with ease

I’ve got the SDD tool.
I guess I’ve got a job at the weekend. Just need to find the flattest ground I can. Disco 4 2012 HSE, Nara Bronze

Is there enough lee-way in the settings, though? With one dodgy height sensor on mine, that corner very quickly max-ed out when I was calibrating for normal height, so I would have thought that if you calibrate it 2cm higher all round at normal ride-height, the sensor will go out of range before reaching the off-road setting. It would be interesting to know what happens when you try! Previously:

Ahhh, so if at normal travel the sensor has 60deg of motion and goes from 0 for access height to say 40 for off-road, I could be moving this to be starting at 10 and going to 50. So risking being at the limit when in action.
But the lift rods keep this range of motion the same, just tells the computer to put more pressure to achieve 0,20 or 40.
No idea if that makes sense to anyone else, but does to me.
I’ll give it a go and see what the computer says when doing the calibration. Presumably it’s sensible enough to not let me set something that won’t work (but that could be asking a lot of LR engineers) Disco 4 2012 HSE, Nara Bronze

Yes, my thinking was that the angles on the sensor (and hence sensor output voltages) remain the same, but the longer shaft on the sensor arm changes the suspension travel before reaching that angle. I'm not sure I would expect a linear change to the ride height at each setting,though.
I think you can get variable rods where you can change the rod length to get the lift desired. I'm pretty sure I also saw someone online who had done they're own lift rods by simply cutting the sensor arm(s) and inserting a suitable length of bolt between the two halves.
Having said all this, I would imagine that only a vanishingly small proportion of Discoveries are ever in a situation where the existing range of travel is not sufficient. I would also be very wary of doing anything to change the centre of gravity for normal road use - I've seen too many stock Defenders and D1s rolled by inappropriately weighted roof racks, when a near-side wheel drops off the edge of a tarmac road...
