It's what Production car racers used to do to lower the suspension on cars in years past when they weren't allowed to 'change' springs.
Not recommended for the road though, as the spring will continue to sag.

ade

Land Rover Tuning <www.landrovertuning.com.au> are advertising a set of 4 "suspension lowering" coil springs at $1,750 (seee New Products link)

In Queensland the legislation states you can only lower the vehicle 1/3 of it manufactured hieght, Quote ffrom the QT

"Lowering or raising of vehicles
The road clearance of a fully laden vehicle must not be
less than 100mm measured at any part of the vehicle
other than the wheel rim or brake backing plates.
(This does not apply where a lesser clearance has been
specified by the manufacturer.)
When lowering or raising a vehicle body (front or rear),
the following additional restrictions are based on the
manufacturer's dimensions for the standard unmodified
vehicle while unladen:
• The ride height measured between the rubber bump
stop and the corresponding metal stop may be reduced
by no more than one third.
• The rebound travel measured between the rubber
rebound stop and the corresponding metal stop
(or the extension of the shock absorber for vehicles
without a rebound stop) may be reduced by no
more than one third.
Queensland Transport,

I have included a link to the booklet.

You are not allowed to cut or heat and press the springs to reduce the hieght as this would effect the design of the vehicle when stopping, I know in the UK there are companies that do lower springs and race 90's, however looking at 20-30mm I believe you should be okay. Legal.

There is an Australian company heres there link if it helps,

hope this helps,

But a spring maker is allowed to reset springs.

You aren't changing the rate, only the free length/loaded heights.

FWIW a Defender runs approx. 65mm or so between the bump stops so 30mm is OK as per the rules in most states.

IMO $1750 for four coils is nuts.
Any of the Aussie spring manufacturers can wind custom springs for a lot less than that.

Yep, $1750 is too expensive for coils. Speak to Dobinsons or someone like that.

Also, look at changing or modifying the bumpstops if you want to increase the base measurement for reducing ride height by 1/3. ie, to get it down lower. Check nothing hits, though it shouldn't be a problem on the non-Isuzu ones.

But would the springs need to be assessed by say the QT or qualified engineer, or do they do that yourselves, for instance as you're changing the original design of the spring (if you're cutting or stretching the spring). Sorry if I sound a bit dumb
