Suspension improvements?

14 reg. 90k miles. Of course it'll be a bit slacker than it used to be however I recall this feeling from day one at 20k miles when I bought it.

As with all my vehicles - some of which at the extreme opposite of this in performance - I like to investigate and upgrade the elements that I don't enjoy. To renew as oem I'm sure will improve somewhat but I'm looking for something beyond that. For example I've seen as many Defenders with different parts on show such as big yellow anti roll bars and have assumed the owner has done so for good reason. I'm hoping for the same inspiration here for the Discovery.

I would say 90k it should all still be decent, apart from the suspension arm bushes, my D3 is well worn with 150k on it.
On the D3 it is common to fit RRS front lower arms as they dont have the squsihy rear bush like the discos have, and this does firm the front end up, also makes the front susp slightly harsher, as the D3 and D4 are so much alike I would hazard a guess you could do the same with the D4.
You can get poly style arb bushes, there are two different diameter anti roll bars, not sure what year/model the change is.
Apart from that there is very little aftermarket susp kit for the discos.

Have a google for MMP land rover, hes up in scotland, but he used to recommend a particular make of susp bush that he reckoned was excellent, possibly superpro? but do ask him first.

You seem to have taken issue with this idea too.

Not really, I just think there are much better ways to waste money.
While there's nothing wrong with improving a vehicle above the original specification, trying to make a 2.7 ton heavyweight into a sports car is something else.

Nothing wrong with dreams, but they're best kept in the realms of reality.

Better ways to waste money, such as?

Where did I suggest I wanted to turn it in to a sports car?

I think perhaps you have me mistaken for someone who doesn't turn dreams in to reality.

Like just buying an RRS SVR, instead of trying to turn a D4 into one.

I look forward to seeing an SVR powered D4 then, and be curious about how much it cost.

Thank you. I'll look in to this.

Does the chassis on frame have much scope for improvement, if indeed that's part of the issue?

Who's trying to do that?

Also curious regarding insurance and if there be happy with such a conversion

plus the sport has the dynamic suspension system

know of a 3.6 into a D3 conversion and he also added the dynamic suspension along with bigger brakes , plus HR tyres

wonder if looking into what the D4 5 x litre has fitted as a guide in what ur need to do

I suggested better bushes and shocks in post 12.

The suspension is compliant from the factory, because that's how LR decided to tune it.
Harder bushes and stiffer shocks would go long way to improving the responsiveness of the suspension, and lowering the ride height a few cm will lower the centre of gravity, helping reduce body roll.
There you are, a useful contribution from me.
