Heavy duty springs.

[bogart]

Have been reading posts regarding the above and am more confused than ever. Ok scenario as as follows.
Have had a 91' 940 TD estate for donkeys years. Couple of years back obtained cheaply 2 sets of heavy duty rear springs. Subsequently fitted a set to the TD no problem.
Have now aquired another 940 (1994) estate and thought "ah I'll fit that other set of springs". reading the posts am confused as to if this is an entirely wise move.
Must admit the diesel to my mind (225k still original shocks) feels nicer at the back than the new one(140k), hence my thought to change the springs.
Some people say with the nivomats, which I am assuming both mine have (look very chunky at the top), one should use standard springs only, whereas others say heavy duty springs okay so which way do I jump?
New one will be used at some time for towing a caravan.

Hi,
I am no expert but this is what I understand about the Nivomats.

They are a self leveling system so that when the car is loaded the ride height is the same as unladen. Standard springs alone let the car sit tail down and the nivomats lift the ride height and look after the dampening.

Heavy duty springs need more weight on them to compress them to the same amount as normal ones, so that they better compensate for the weight of the caravan or other loads.

If your springs are tired, then with new springs, heavy duty or not you would notice a difference.

As new heavy duty springs are not dear why not fit a pair and try them. If your shocks are worn then replace them with ordinary ones, again not expensive.
