-30mm front, -20mm rear, max.  That's from standard. MV6 is already 15mm lower all round.

So since Eibach springs seem to be 30mm lower, does the kit come with different springs for the rear and front?

I wouldn't get too hung up on written values. The springs will change the ride height from where it is to wherever it goes, usually lower if you fit lowering springs. Eibach -30mm springs dropped the front of mine by 20mm and the rear by 15mm one side and 22mm (it's now level). As an estate, the important thing is that it retained it's slightly tail up stance so the front/rear relationship is as intended.

OK, thanks. I just asked because it was said that -30mm front, -20mm rear is max. and if the Eiback set the rear to 30mm it would be then too low it seems.

Think I'll definitely go for the Eibachs then.

I'd like to 'give them a go', have a ride in someone's motor which has them (I think there's a lad not too far from me, actually) because they get good reviews, but I do try and keep my Omega as the spongy, motorway-eater she is.

If I had a 3.0 / 3.2 manual which stood more chance of being more of a sports car, then I probably would, give it a bit of the Holden HSV treatment. Or just get a Monaro to begin with!

You can go lower, just requires camber correction bushes

Yes, with all the same impracticalities of slammed cars. There are no further benefits.

Mine had to be bumped back up to -20mm at the back as I was wearing out the diff casing, and kept bending the rear bumper supports.

I really don't know how that can happen, my estate is -50 on front and -40 rear, yes the exhaust catches slightly on speed humps and the towbar down the other side but even full of rouble in the boot I haven't hit anything major. Are the saloons that different?

I am mearly saying you can go more than the advice of 30/20mm, it's pretty obvious the lower you are the closer it'll be to speed humps and the less suspension travel will give a harder ride but I'd do it all over again and more of it was cheap enough!!!

 Not after slammed, just a moderate lowering and as I've used Eibach before on my old Vectra I'll probably use them again but just wanted to ask of  here for other options. Don't suppose anybody has any pics of their cars on Eibach springs by any chance?

+1 on Eibach. I have them, its -30mm front and a bit less on rear.
It's still a normal ride, noticable harder (less roll, but also more noticable kick over bumps) and cruise comfort is not affected.

Going lower that this, IMO, will create problems with every-day use. Even with this small drop, I have to be careful when going down the curbs or going on a ramps, not to touch groung with sump or floor.

What is the perceived benefit though? Surely GM got the balance right with the MV6 as one imagines they had a reasonable budget to sort the thing out....

Vx want what will sell, I want something with no arch gap and a tidy fitmemt to the tyre.

Obviously the car and suspension is designed to all be at the stock high, anything different I guess sacrifices will be made.

Its not really speed bumps that cause the issue, as you naturally go slow over them. Its country roads that the arse drags on, as soon as you get up to a decent speed.

Right, that makes sense, you want to lower for looks - style over substance - that's fine


But people wanting to use their cars, especially enthusiastically, would do well to head the -30mm/-20mm advice .  I ignored it on the rear, thinking it would be fine, but I was wrong 

Additionally, wide 235 tyres, such as the rather overpriced GY Assym F1's and most 245 tyres will wear out the wheelarch liners at the front at -30mm with very enthusiast driving.
