hi there guys
just a quick question I have a 2.2 petrol the problem I have is that my suspension looks low on the back and high on the front it was not too bad before I put on the elite alloys and boot spoiler now it looks awful at times.
I have checked all the suspension everything is ok.
can I put lowering springs on but which ones do I go for to make it look better 30mm-40mm
cheers

Could be broken rear springs :-\
That's to say, the car should sit level regardless of the suspension fitted :y
To add, obviously if the incorrect springs/shocks are fitted to one end or tother, then it won't be level...

hi there
I have just had my car mot`d all springs were fully checked no damage as this was my first thought too.

Wrong springs fitted then... anything in the history?

Will check the history but what size shall I change it too 30mm-40mm
Cheers

Depends what's been fitted and where...
Dropping the car more than 20-25mm will cripple your tyres as the camber will be impossible to set to avoid excessive inner edge wear :-\
Estate springs are a different length to saloon ones and four cylinder petrol springs are different to diesel and v6 ones...
Sports springs/shocks were fitted to 2.2 Sports and MV6 models, but these are different according to the engine/gearbox fitted...

It does happen, my 2.5 is too high at the back - wrong springs I suspect as there is evidence of replacement in the SH.

If the rear wallows then you need to replace the rears. Fit standard springs for your car (not sport or elite) to achieve 675mm ride height (measure floor to wheel arch) should be same front to back.
If no wallowing and your happy with the rear and WANT to lower the ride height then subtract the actual rear ride height from 675mm. Then match the front to that to give your lowering measurement.
However. As Al says, if the rear is lower than standard (675mm) by more than 20mm the rear suspension settings are not achievable. In which case sort the rear springs for the correct ones to match the front. Or rear inner edge tyre wear and a wandering rear end will result.
Odds are, if you see a visible difference between front and rear, it will be more than 20mm too low anyway. So change rear springs for the correct ones imo.
Could start by posting up the ride height measurements on all 4 corners. Floor to wheel arch, by the centre of the wheel. It's usually a good indicator if how worn the springs are. :)

Then you have the fun of trying to work out what is correct and where to get them from!

Mine sits higher at front than back, never really felt it was an issue tbh :y

Hi guys
The measurements for both the rear height is = 662.94mm
The front drivers side is 673.1 mm
The front passenger side is 688.34
What do I need to change the rears or fronts.
Cheers

Up to you. But it's the rear that's the problem as you say. It's easier to change the rears. With less set up implications. So cheaper.
Might be worth identifying the rear springs first though. They could be sport springs. Unlikely, but could be. Your looking for an an ident, such LA or LM or similar printed on the coils. Or whatever.
Do you carry any heavy loads in it?

You say it looks awful "at times" :-\ do you have a boot full of heavy stuff "at times" then ?
Or if not what is differing between "at times" & and normal ?
As Mr. Gixer says front drivers side is about right for standard suspension , although front passenger side is a bit high
( 13mm ish ) Just out of interest , have you got the same make of tyres on both front wheels or is one really low & the other nearly new ? Will presume that tyre pressures are correct ?. . . The back is 15mm ish lower, which would suggest wrong springs or possibly knackered springs :-\
As Chris says check for spring Ident marks & post up on here .Front springs are colour coded, usually with 3 small coloured stripes, for example orange/grey/orange. Rears have 2 letters in white paint .VX dealers do have a bad history of fitting incorrect springs ::) ::)
HTH :y

Sachs rear springs give me bang on 27 inches from floor to wheel arch. try them :y
-
Btw there does appear to be a 10mm tolerance on the 675mm measurement. Both on the spec wheels in motion quote, and by measuring various cars. Some variance is inevitable obviously.
Where the Sachs from All Getman webby? There is a link to their on line store in parts section if needed. There's a phone number if the site isn't working.

No, Chris. They were brought from ECP.... but defo Sachs :)
Ps, good to see you back mate. Was missing you :'(....got to have someone to wind STMO up :)

Stear clear of that lad. He's a wrong'un ;) ;D
-
Stear clear of that lad grumpy old scouser. He's a wrong'un ;) ;D
Corrected for you mate :y

I think I'd check out reason for ride height difference at the front first.From your measurements there's a 15.24 mm variation which whether within tolerance or not is a fair difference assuming tyre pressures etc.are correct.Once front sorted then I'd possibly look at the rear set up.If the car still handles alright and it's just the look that's bothering you then you can decide if it's a cost effective fix.

Hi again guys
Please can anyone tell me ow to upload photos and it will show the look and then it will be easier to see or get a better idea of what my next move will be.
Cheers

Guides on posting pics, sticky at top of newbie section :)

hi guys
I am just in need of confirmation is the ride height from the ground to the arch all round is 675mm (67.5cm)
the omega is a 2.2 with 235/45 R17.
cheers

Yes (except 2.2sport or mv6 which is lower sports chassis at 660 )10mm tolerance allowing for body panel gaps and spring wear etc.
-
After thought.
... re pre face lift, which is also 675 standard ride height, but not sure if pre face lift mv6 is also 15mm lower. Think it is lowered by shocks only going by Oof legend on here, just has different shocks, but not sure. :-\

Hello again
Would anyone know the part number for the rear springs on a 2.2 petrol 2002 build I am looking for sachs but there is a couple of part numbers for the same part I am confused I have tried to contact them but no reply and no answer on the phone.
Cheers
