Eibachers - Please Comment on Comfort

There is enough conflicting information so Im hoping to get the straight dope on this topic.

Some might remember ..
I drive an 08 3.0si slush box.
It has the 'sport' suspension.
Now am I to believe that installing Eibach springs will give me a more comfortable ride.
I understand I will get minimal lowering cause the sport suspension is already dropped a bit.
But somewhere I read that the BMW rear springs are extremely stiff while the fronts are too soft.
Eibachs are supposedly 'just right"
And a true 'seat of the pants" review from some experienced arses would go a long way to saving me time in the doghouse if I re-spring and someone gets 'sore"!

Cheers

I have a 3.0si on Eibachs, Its quite hard to explain, It's definitely more controlled, a little firmer but not crashy-for example it didn't make my car creak or rattle compared to the M sport springs. The ride I would say is on the whole smoother - seems to iron out the bumps better. I'm on standard shocks/18" wheels.

Sorry not very technical but I'd give them a clear thumbs up :)
 
As above definitely less bumpy but more harsh at the same time... But it does lower it noticeably more... So speedbumps/ multi story do come more challenging.

Is there another option for better springs without lowering the car so much? I have a 2004 3.0i which I presume means I have the M Sport springs (or was this only introduced post facelift?). I'm looking to stiffen the car up slightly but from the description Eibachs (and pretty much all other brands) they lower the car by around 30-40mm which in my opinion is a bit too low - I already grind the floor of my car on a speedbump going into my gym so I dread to think what would happen if it was even lower! I think it looks good at that height but I'm not sure how practical it is - my car needs to remain a daily driver.
 
I'm in a similar position , I know fine well from previous cars arbs alone make a huge difference to the feel of a car , much more planted and stable with no real ride deteriation , or I'm also considering a uprated shocker , bilstien b8 work with std height springs I'm lead to believe .
Has anyone any experience of either of these options with std springs ?

If you're running sport springs as standard then the Eibach's will only drop it another 10-15mm. I installed mine a few weeks ago and haven't had any problems with rubbing or speed bumps etc. :)

Ah great, I'd be happy with 10-15mm reduction. Yet another purchase on the long list of things!
 
I'm awfully tempted to go the Bilstein B12 route....

at that price it really is rather tempting, but I don't know really if I can justify the additional money over the Eibach springs alone, which most on here say is a real improvement in body control with the OEM dampers. I'm not looking to break the bank to make the car a track hooligan, but a little sharper on the road (as you seem to want) without compromising ride quality too much is to me a worthwhile proposition!

Not meaning to hijack your thread OP, but hopefully this will be of use to you too; what uprated ARBs have people generally gone with for these cars?
 
I actually don't think there's much difference since fitting the Eibachs, rides is still smooth and comfortable, car doesn't crash about and feels more controlled.
I have 19's fitted, but I think this made the most but slight difference to the ride.

Thanks for your review.
Sounds like the Zed becomes better balanced with Eibachs.
As I mentioned - I already have the sport suspension and would expect minimal 'lowering'.
Lowering isn't my reason for a spring change.
My understanding is that the Zed's suspension setting are based upon "Ring" performance.
And that testing resulted in a very stiff rear calibration.
I think somewhere I read that the Eibach's rear springs are almost half as stiff as stock.
And the fronts are marginally stiffer.

Thanks again for your evaluation.
