Could anyone recommend decent coil springs for my 2.6? While it is off the road, going to change the back suspension as it is a bit tired.
I have found these, but not sure if OK, they say inconstant spring design which I understand gives the best of both worlds, in different loads and keeping the wheels on the road better. The car is a standard factory setup, no air suspension.

Thanks in advance for any help.

Kilen HD would be my recommendation. Fitted to several Omegs with good results.
All V6s/4 pot diesels have the same fronts, and all 4pot petrols have the same fronts. 2.5td/dti has its own springs because the engine is a heavy bastid.
All saloons use the same rear, and all estates use the same rear.
There are a few other variations, but unless your car us a limo, armoured or a hearse, they're largely irrelevant.

Thank DG for the quick reply. I have seen Kilen, but wasn't sure about them as I personally haven't heard of them. I will look for a pair now.

Also dig out a pair of Sachs shocks. Ignore the engine, these are the correct ones (they're all the same for non self levelling saloons) and for some reason, heavily discounted...

Best springs are MV6 ones... if you find low millage set grt them.. sits perfect and handles well..
I had eibach on mine and found didnt handle as well as with mv6 springs and front was to low for my liking.
Or grt in contact with sheffield coil spring and have a set manufactured to oem mv6 set brand new

Two of these

is about as cheap as these ones get. :y

Eibach will sit level if you get the correct ones for your engine... They drop 30mm from standard (15mm lower than MV6) but 4 pot petrol and v6 are different.

Personally I like Eibach all round but a nice compromise if you needed to carry weight in the boot was MV6 LSC (when they were still available) on the rear and Eibach on the front, the stiffer fronts helps to dial out that slight understeer when pressing on through a corner.
That said, if keeping a car standard I would go with Dr G's advice.... it's plenty capable, I just prefer a slightly more handling orientated setup with the tried and trusted various poly bushes, top mounts etc as recommended on this forum... all personal preference really
-
My plod always had plod fitted and was ideal, the Elite had full Irmscher springs and shocks with SL deleted.
My last Omega had Sachs shocks and Kilen springs all round plus polys front and rear and handled as well as thr other two. All estates, but the principle is the same.

One thing that would be worth checking while you are working in that area is the shock absorber top mounting area, would be well worth a good clean up, check for rust and if all solid a spot of rust converter if needed and some paint / underseal applying. Due to the age of these cars it's not uncommon to start to see this area beginning to corrode.

This.
Terry can tell you what happens if you don't.

Hi Doctor Gollum
Thank you for the link to the pair of springs. I contacted the company to purchase them. They asked for my Reg No. And are now saying that they will not fit my car. It is standard setup not self levelling. I will believe the members advise on here more than their's. If I purchase the pair in your link (Kilen Code 60037), will they fit with no problems?

Sorry for asking.
Thanks for all the help. Take care

The company are being 'special'. They are categorically 100% the correct springs for your car.
Just buy them without contacting them. ;)

In total there is 19 different rear springs for Omega Saloon and Estates, that number includes some special builds like armored and hearses.
Look here for the correct ones:

One of the ebay sellers compatibility list says the Kilen 60037 are for cars with self levelling. That seems to be bull.
Don't rely on ebay, or the sellers. It's best to directly check the manufacturers application lists.
For a 2.6 saloon without self levelling Kilen lists three (https://web.tecalliance.net/kilen/en/parts/cars/assigned?assemblyGroupId=100011&targetId=15327&typeNumber=15327&targetCountry=GB&brands=176&pf=2&page=0#@brc/brands:Car;targetType:cars;mandator:kilen/assem:VAUXHALL%20OMEGA%20(B)%20Saloon%20(V94)%202.6%20V6;targetType:cars;mandator:kilen;targetId:15327;typeNumber:15327;targetCountry:GB/lnkparts:Suspension%2FDamping;targetType:cars;mandator:kilen;assemblyGroupId:100011;targetId:15327;typeNumber:15327;targetCountry:GB;brands:176;pf:2;page:0l) possibilities.
71026 = Coil spring with constant wire diameter = GM 90487520
260640 = Coil spring with inconstant wire diameter = GM 90487520
60037 = Coil spring with constant wire diameter; Reinforced Version = GM # not stated
So the 60037 springs will fit, just they are reinforced which presumably means heavy duty.
My guess is that the 260640 inconstant spring is a standard duty but improved version of the 71026 standard constant wire spring.

Heavy duty is kinda the point. Standard Elite springs are soft, even more so after 17-20 years of abuse.
Heavy duty with self levelling is a factory spec, usually fitted to UK Police vehicles, (self levelling less so on Police saloons) but never the less, they do the job most satisfactorily without affecting ride comfort/quality ;)
-
Springs for self levelling are softer as the shocks are designed to carry some of the weight.

Worth bearing in mind that the shocks are essentially irreplaceable so standard shocks will be fitted at some point, and the combination of soft springs and standard shocks will be borderline dangerous ;)
-
Whereas self levelling shocks with springs stiffer than elite spec improve the car enough to make you wonder what they were thinking when they decide to fit those really soft springs.

Exactly.

The discussion is about whether the 60037 Kilen rear springs are suitable.
In this case the car, which is a 2.6 saloon, does not have self-levelling? Did it ever?
The ebay seller says they don't fit the OP's car. The Kilen website says they do. With the caveat 'reinforced' and not for self-levelling. So presumably heavy duty.
Kilen list another constant rate spring for a 2.6 saloon without self-levelling. This I assume is the standard duty drop-in
.
Kilen also list an inconstant version of that spring.
-
All Elites have self levelling as factory standard. ;)
As for the constant query regarding the recommended Kilen 60037... your muddying the waters and overcomplicating this.
The original question was "Recommendations for the best coil springs for a 2.6 saloon.", to which the answer remains Kilen HD, which, for the saloon means 60037 for all the corroborated reasons outlined repeatedly above.
All the referencing to original springs is fundamentally irrelevant as the original springs are no longer available ???

The OPs profile suggests the car is a 2.6 CD, not an Elite.

Doesn't matter.

The HD spec with raise the rear ride height v std.

Nope, not in my experience.
Obviously it will correct the ride height of 17+ year old springs, but it should end up with the arch height being 'as new' allowing for slight variations in individual springs ;)
-
The HD spec with raise the rear ride height v std.
If the S/L is working properly, then it is setting the ride height. Changing the spring doesn't affect that, even if it's overdue. What does happen is that the S/L won't need to work as often or as hard. After fitting stock rear springs to my Elite, the compressor was rarely needed in normal use. The car both handled and rode better, as the additional air spring is a bit of a bodge. New front springs instead of saggy 17 year old, 180k miles, ones raised the front of the car 30mm to stock height
Having stock springs also means that when the GM shocks fail, you can fit ordinary ones.
