I don't know about the sprung D3's, but other vehicles I know of that have had spring lifts or body lifts have started to chew through CV joints like there's no tomorrow. I'ts all a matter of degree.Have a nice day!

I thought the reason for the auto lowering was for safety (LR's not necessarily the driver) so folks don't sue them. The D3 is stable at speed in off road height as folks who have found it stuck at that height have found out. One inch extra on a very stable vehicle.
I would not do it to a new vehicle but if it was an old one it may be worth a play.
Is anyone going to keep an eye on the post and let us know how he goes?“There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

What he ^ said.
James obviously posted this mod to see what the reaction on here would be, no one has slated anyone, we have just given our opinion. I will have a wager with with who ever wants. I bet this chap changes back to standard ride height within a month (or is dead). The reason for this is. To obtain the extra height the suspension has pumped its self up and increased the pressure so the ride is going to be very uncomfortable. And the fact that suspension travel will now be limited thereby reducing traction. I have driven the Blue Pearl places in standard off road height that the Matzker demo D3 with the suspension set to max was unable to get to. The Matzker D3 had to be winched out I was the next vehicle through and the Blue Pearl drove through effortlessly.
Later that day in super extended mode I shattered a front drive shaft In the Beginning there was nothing, which exploded.

I was wondering what would happen if he put it into super extended with that mod. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

Or, stealing your idea here now ND. Although aren't they like this 'down under' anyway?
IE - 05 D3 TDV6 HSE - Zambezi Silver
SA - 07 VW Golf TDI - White - Sold!
Of course they're entitled to their opinions - ummm - as am I??? IMHO, the person who isn't represented here, hadn't in fact done anything too serious - and it had been done by an LR mechanic, so, well - just ... my opinion

Though I do like the idea that the D3 has so much extra grip "down-under", that we can can cope with driving upside-down on the bottom of the world...

If it has been done by a LR technician, are LR or the dealer he works for assuming responsibility for the mods? I doubt it - more likely the LR tech has done it outside of his work time or without the service managers knowledge...

I think that being able to manually raise the suspension into super extended mode would be a very helpful modification. Sometimes you need more ride height to avoid scraping on stones etc. Other times you need a lot of flex in order to maintain traction. I was under the impression that the Matzker Selective Control suspension system didn't become firmer in offroad mode (based on a test I read in a Land Rover magazine)? I would like to hear from people with personal experience or observations.
Lifting the vehicle 25-30 millimetres isn't going to wreck the CV joints unless you drive in offroad mode all the time. And I certainly don't think it's going to make the vehicle significantly more unsafe. Using common sense and a little caution will easily compensate for the negative consequences like higher CoG. So, don't go fast in extended mode. If sidehilling, lower the vehicle.

25-30mm will put approximately another 10 - 12 degrees on the CV joints... the issue isn't speed but torque and steering angle, torque is normally about 25% to each wheel, should TC or DSC kick in, then torque seen at some of the wheels can be up to 40%- 50%, combine this with an acute steering angle and it's goodbye to those ball-bearings Torque is at it's greatest in low ratio and low gears, 1st gear in high ratio is roughly the same as 3rd gear in low ratio, so the application of torque is roughly 3 times as much in 1st gear low ratio as first gear high ratio, high torque application can also induce wheel slip with the potential consequence of excessive loading should a wheel suddenly regain grip, the turning moments and dynamics of the drivetrain can mean that this translates into something letting go
you are of course correct that 'common sense' would need to be applied in the use of this modification, unfortunately, a full wallet and an eagerness to empty it does nor imply common sense is present or adhered to

The matzker system is a much better solution, it is an electronic box that changes the values from the ride height sensor given to the computer that controls the height of the vehicle. With a switch you can, in Off Road Height, get an extra height of 26mm, and in Normal mode, you can lower it an 23 mm extra.TDV6 HSE Stornaway Grey, black interior
