Warranty voiding question - Suspension.
Hey all,

What can and cant be done to improve the suspension/comfort/handling on a MY2012 D90HT?
I understand the CSW springs are fine for lighter loads but also offer a nicer ride.
My guess would be that i would rarely be carrying more than 150Kg(max more likely half that most days) tools and parts.
Mostly computer/server kit for delivery or servicing.

Can i up-rate to OME springs and dampers without voiding my cover? Or would the CSW OE spec springs suffice and still avoid trouble with LR?

Thanks,

Chris.

I thought that the CSW 90's had HD springs as standard?

i used standard LR 2400kg SW road springs and Koni dampers.

my hand book stated front tyres at 30psi and rear at 38psi. I run them at the recommended rated stated in the workshop manual at 28 front and 35 rear.

the above for me made all the difference, remember 150kg load is about 2 people.

spring info below:

Road spring Part number Colour code
90 2 seat utility (2400 Kg)
Front - Driver's side REB500200 Red/green/white
Front - Passenger side REB500220 Red/green/orange
Rear - Driver's side NRC 9448 Blue/red
Rear - Passenger side NRC 9449 Yellow/white

Interesting, i will try tyre pressure first then.
150KG load would be a rare event, my tools are about 20KG and two/three servers might make 60Kg.

Its just when rolling over speed bumps i need to get down to a total crawl or the back end snaps down again sharply and any kit i have stowed gets a slap. I am not a fast driver, i dont mind speed bumps too much usually but this is very noticeable.

I though the softer springs might help after reading something about CSW versions being used in this manner by someone else on here, cant find the thread again though.

there are many opinions on here by some very experienced people who all get my respect, they have taught me a lot.
one good suggestion i listened to was put on quality shocks which help with rebound etc. BM52

Yes moving to Koni/OME would be fine with me, my concern is whether or not LR will let the warranty stand.
I might call them about it.

If you change shocks and springs and then have any kind of drivetrain issue at all, it is unlikely they will honour a warranty BUT it does depend on the dealer. eg lakeland landrover dont care at all, they say "everyone does it, if we said no to a problem we'd never honour any warranty work"

I had iron man springs and shocks on my previous 90 and it was superb - transformed the ride and handling. much cheaper than OME etc but equally as good.

Drop front and rear tyre pressures to 30 psi. It will make a huge improvement to handling and ride comfort. Indeed, you can probably drop to 28 psi if you are not carying much gear. I just did over 1,000 km on dirt roads in central Australia with a load of camping gear on board with tyre pressures all round at 25 psi. Ride and handling were excellent. Speed was generally at about 80 kph.

I have read good things about Iron Man kit. The only place ive seen that sells it in the UK is West-coast.
I know when the warranty runs out i will no doubt replace the suspension and a few other bits, but now i want to keep the warranty for any big expensive things.

Tyre pressure it is then, will do it tomorrow and see where it gets me.

Thanks all.
