It's the other one I need.

[Diamond Black Geezer]

The Monaro uses the same rear wheel bearing as the Omega B estate... Doesn't make the rest of the suspension the same...

Simply responding to the OP's request that the tails be the same, or not

ajsphead, the above link shows the top mount/rubber stop to be identical on Sennys, Carltons and Omegas, too.

Omega A Evo 500 front is 1065.945kg, rear is 919.055 based on a gross weight of 1985kgs with 53.7/46.3 front/rear weight distribution. This assumes that the Evo 500 weighs as much as a 3.0 Gsi... Payload is 500kgs...

Think you'll find Omega B has a higher gross weight and higher Payload... Certainly both my estates gross out at around 2450kgs

And DBG I repeat my previous answer...

Gross weight for a basic DTI saloon is 2145kgs, more with a sunroof/tow bar/Elite... That's two passengers with luggage, or three passengers with no luggage...

Axle weights are on the drivers side B pillar sticker.

Fit those springs and you turn a perfectly good car into a two seater which will handle like a dog, right upto when the springs snap

Thank you.

I'll look at the parameters for the DTI springs as they cross over into different Omega models with considerable variation in loading. At least I have a parameter for the other ones now.

[ajsphead]

Thanks for your help Al. I now have my axle loadings. Front 1055 Rear 1230, GVW 2265 so by any reasonable reckoning it's a solution for a 2.2DTI.

I also know there's been some debate about whether springs are handed or not. There's no consistency from different suppliers, some do and some don't. The GM parts list is not helpful as springs are listed for a set, so I'm going down the handed route - costs the same so I don't see why not.

[05omegav6]

Your payload will be 280kgs less so basically no towing, nothing in the boot and only two passengers... Payload being gross weight less kerb weight.

Oh and be sure to tell your insurers otherwise you won't be covered when the inevitable happens

In other words, on your head be it

Why not just get the right springs, designed for the Omega?

Its desperately easy to cock up the handling, and some, like understeer gradient, are likely to put you in a ditch (admittedly most likely backwards).  You're probably looking in the region of a 67% understeer gradient, go to 65% or less, you could be having a trip in an ice cream van, or worse.

This is precisely why we recommend certain springs, designed for the car. We have all sorts of 'tards come on advocating cut down Corsa springs, coilovers (with no idea how to do the maths to set them up) and so on. Sadly, these very people are the type that won't admit they've cocked it up, because they've slammed it and it looks really cool, init?


If you must go ahead, you have to have it in writing that it has suspension modification not approved and not recommend by the manufacturer from your insurance. Actually I'd add that it wasn't even designed for the car.  Obviously, you have a responsibility to other road users.

[The Sheriff]

Excuse my ignorance but..why would anyone want to lower/stiffen the front of an omega 2.2 diseasal? What are you planning to do in it?
If it's more grip at speed you're after, dump the omega and buy something that goes round corners better, there are plenty of candidates. I'm all for improving the appearance and setup of a car, but we are getting into the realms of silk purse and sows ear on this one. 
Plus, as has been said, it's dangerous to wander so far from the norm.

[Diamond Black Geezer]

Just returning to a previous question posed - Did anyone find out how many springs are supplied for the Omega now? Excluding LSC/MV6 ones, of course.

Can't exclude them as they're factory spring options...

Below is what I recall seeing from previous versions of the EPC and is only a summary of available spring options for the Omega B...

4 types of LSC: 2.2 petrol saloon/estate; V6 petrol saloon/estate. Might be plus diesels in certain markets...

8 types of Standard Non Leveling: four cylinder petrol saloon/estate; v6 petrol saloon/estate, four cylinder diesel saloon/estate; 6 cylinder diesel saloon/estate.

8 types of Self leveling: four cylinder petrol saloon/estate; v6 petrol saloon/estate, four cylinder diesel saloon/estate; 6 cylinder diesel saloon/estate.

16 types of Heavy duty Ambulance/Hearse/Limo/Armoured, 8 Non Leveling, 8 Self Leveling: four cylinder petrol saloon/estate; v6 petrol saloon/estate, four cylinder diesel saloon/estate; 6 cylinder diesel saloon/estate.

16 types of Heavy duty, NOT Ambulance/Hearse/Limo/Armoured, 8 Non Leveling, 8 Self Leveling: four cylinder petrol saloon/estate; v6 petrol saloon/estate, four cylinder diesel saloon/estate; 6 cylinder diesel saloon/estate.

16? types of Rough Road Package, Not Ambulance/Hearse/Limo, 8 Non Leveling, 8 Self Leveling: four cylinder petrol saloon/estate; v6 petrol saloon/estate, four cylinder diesel saloon/estate; 6 cylinder diesel saloon/estate.
