I've had a Discovery TD5 on air
I've had a P38 on air and now a 3 on air
one of the reasons being the ride, have driven both the TD5 and P38 on springs and was unimpressed, no reason to believe the 3 would be any different.
TD5 (7 seater) had the air on the rear due to the increased weight capacity of 7 bodies, presume the 3 is the same. Unsure if the 3 came with the option of springs from the factory. If not wonder as Gary says how it might affect your insurance as it would be seen as a modification


thks

does me u wonder what there opinions would be , but with coils surely it’s got to react differently with stability , cornering , driving at motorway speeds and especially under emergency braking situations

wonder how long the bushes last coils vs air


I don't know of any performance cars that are used for trackdays on AIR if it was better why is it not seen on the track. Like I say this technology is passed down from the HGV's good for towing and self levelling when carrying differing loads.

I have used GENUINE Land Rover parts except EMU springs. Coil over shocks will always be hard to beat for road handling !!

Each to their own but its my preference I would never have put my Mitsubishi Evo's on air bags lol

To be fair, it hasn't just 'gone'. It was bought, with issues for somewhat over $2,000.
Since I had the loom repair in the NSF wheel arch (IIRC) done around 6 years ago I've had zero problems with the air suspension and wouldn't be without it.

If I couldn't lower the suspension I would have to throw my 91 year old mother out with a parachute and get her in with a fork lift Whistle

I Still have ALL the special functions!!! I have no idea what all the flack is about as per insurance I have use OE components I have no idea why all the oppression I think its time to move on to another forum
As for the interest regarding my insurance!! I have specialist insurance and keep them updated on modifications that's if its any of your nosy faced business, I have had much more radical tuned cars in the past with all mods carried out with non OE components without issue. I am keeping the vehicle and have no intention of selling it its for expedition runs into remote places, places where a suspension fault could leave me in a dangerous situation its my business how I RISK MANAGE my vehicle ......where does yours go ....TESCO's

How VERY DARE YOU!!!



You are insinuating that I only go to Tesco in My Disco!!!


My Local Tesco is very small and I prefer Lidl and Aldi as they do have a much better range of Cutting Disks etc.. (when In Season!) Very Happy

Ref your conversion.. Good for you...


TBH I'm tempted to convert one of mine as I have had them both fail in the last week in terms of the Suspension Big Cry

Many a casual user might just conciser the upgrade an improvement over the air suspension.. Not too long ago buyers of second hand D2's used to body swerve ACE versions due to the costs.. and the Coil Spring versions were (still are?) seen as more reliable??

LOL Rolling with laughter Rolling with laughter

I simply did it for long term reliability. I envisage an ageing D3 will have enough troubles so far I have done upgraded new Torque converter, EGR valves, Inner front CV boots, replaced calipers and discs, replaced 12v sockets with USB's, Fitted coil overs, replaced Anti-roll bar bushes. That's my first year of ownership ex police immaculate service history. passed MOT first time in September. I plan driving to the far east when I retire among other exotic remote places so hence as many fail safe modifications as possible. I had criticism about it being a Defender but I can assure you after taking my Camel Trophy 110 to the Red Square the D3 is far more comfortable, and I don't mind reverting back to Defender technology in the running gear at least it was bullet proof. mine will still be with me in another 10 years!!! Will yours?

I do not believe that you have full functionality of terrain response. It interacts with the air suspension. It may have been worth your while reading up on the system before killing it!

It's perfectly possible for the system you have fitted to 'drive' better than a worn out air suspension system, but not overly likely to outperform a perfect 'as new' air suspension.

Reliability? debatable. You probably now have less potential points of failure, and for the intended use of vehicle, may well be appropriate. Others carrying out such a conversion may not be so particular in choice of components. You referred to using only LR parts, yet the springs and shocks are both aftermarket items??

The points around type approval for carrying 7 passengers and for Xenon lights need to be born in mind by anyone carrying out such a conversion - eager MOT testers etc ...

Re the 'attitude' of forum - I'd imagine it centers around your adamant insistence that coils are better than air ... a point that is at best 'debatable' rather than 'fact' Thumbs Up

Would I take my D4 to Tesco's ... not if I can help it.
Will I still ave it in 10 years ... depends entirely on the new Defender.
Are you the only person to have ventured further than Waitrose ... No! Very Happy

Censored comments really Shallow Hal springs to mind my shocks are Dunlop idiot, standard fitment !!! I have put uprated springs to cope with my loaded vehicle.

The TR programs do indeed interact with the air suspension "raise vehicle to use this function" that's all lol

My replacement ECU tricks the system so I have reduced throttle response, I have TC for best traction and HDC what else do I need having got stuck on air where defenders and coil Discoverys proceeded, I have since driven that section on coils without issue.

I invite you to have a drive of my vehicle instead of putting silly comments on here as I am bored of answering them with technical evidence having driven both you have only driven air.
