I’ve had OME springs (2 inch lift) and shocks on my 100 series for 3 years now and think they are great. However they are the medium weight ones and I get a lot of rear end sag when the car is loaded. Unloaded the car sits and handles perfectly.
I’ve decided that something has to be done to correct the problem. But what? Should I replace the rear springs with OME heavy-duty springs, same as what I’ve got but with the extra 200 kg carrying capacity or add some Polyairs? What are the advantages and disadvantages of either one?

A set of heavier springs (864's or for real heavy work, 868's) will give you a firmer ride unladen, slightly higher than what you have now aswell...they do make the car handle abit better and dont squat asmuch when weight is in the back.
Comparitively, medium duties are 19mm wire, 864's are 20mm wire, and 868's are heavier again....possibly 21 or 22 mm thick wire.
They would be easier to fit and cheaper than the bags. Not bagging the bags at all, but if you end up relying on them too much, you could possibly be let down.....sorry guys :@) seen them holed b4,although very rare, not sure how much they impede articulation offroad....ive always gone with the spring option.

Andrew,
Originally, I thought upgrading
the springs would be the best option, but I’m worried that everyday driving when not loaded would be compromised. Are
the springs you mention progressive; i.e. soft to begin but firm up as the spring compresses?

Gday Chris
The springs you should have now is an 863, and it is a linear load spring, meaning all winds are thesame. The 864 is aswell. Both these springs are load carrying springs, the 3 is rated at 250kg's constant and the 4 is 400 kg's. It sounds like you actually have 860's in the back, which are the comfort progressive spring.... if you dont carry much around in the back as a norm, i wouldnt go with load springs...but if you have a Kaymar on the back and draws in the back, then they are ideal.
There are a few options open to you, air shox, air bags and probably even more safe would be load leveller bars.....not obvious to most, but weight on the towbar takes weight off the front wheels, effecting braking and steering....load levellers are excellent for my van....i lost a wheel around a corner last trip away, and they may have saved me having an accident aswell.

Sorry Chris, thought you were towing for some reason......if you have 860 progressive rears, i have a set of 963's you can try, to see if you like them...i actually prefered the firmer ride of them over the 860's, as it wasnt harsh at all and made the car sway less in corners.

Changing to the heavier springs WILL make the car ride harshly when unladen. It will also have it's arse up in the air too. Depends on how much driving you use it for, laden and unladen. The Airbags can be adjusted and will not compromise the ride when unladen because they can have the pressure let out of them then. However, if punctured off-road, you are left with no load assistance to your soft springs. But you can always carry a spare set, they are easy to fit, if need be. Personally, I use two sets of springs which I change depending on the trip and load I'm going to do, takes about an hour to change them over.
