I agree with this.... That's why I went Eibach as well. I hate the slammed look too, childish in my opinion. The Eibach's are nice cause they give a noticeable but subtle drop and there are zero clearance issues. I never bottom out or hit the bumper with them. They definitely do make the car look more aggressive too. The gap just doesn't look right over the front tire from the factory.

$5,000PaintJobM3: You get better shock rebound/damping from a set of lowering springs? That sounds like a patentable technology, whoever sells those better call a patent attorney! A nice set of coilovers might (and might not) provide better damping but that's not what you're saying, you're talking about a drop.

By the way, "dampening" is the act of making something "damp." If your springs are getting your shocks wet, something is wrong.

Obviously I need to get out of this thread before I start trying to inject facts into it.

This is one those areas that I'm trying to learn more.

One thing, very firm suspension is not good on bumpy road, though with EDC that can be covered.

Tires need some suspension travel, because when the suspension is compressed, you get more negative camber. So in straight line, you have some x amounts of negative camber (preferably not too much), and when cornering (which is when you need more negative camber), due to weight transfer you get more negative camber. So if you lower the car so much, such that you're having very limited suspension travel, how would that effect this 'dynamic' negative camber?

Also, weight on tires increases their grip. Not so much of course, but having some extra weight on a tire increases its grip. So firmer suspension, less body roll, less weight transfer, less grip on outside tires during cornering... But than there is a bit of testing required here to find the limits of tires in terms of handling the extra weight due to cornering.

Any inputs?

+1. Eibachs here with a front lip and no scraping or white knuckle moments.

Waiting for Dinan to come out w ZCP specific springs. They will probably just lower it a tad more plus new bumpstops. The best bang for the buck and maybe get the front swaybar out of an E93 convertable, I heard thats a little bigger. That would be a great setup. Anybody who knows about springs nows progressive rate spring is superior to oem.

One thing I and the people with me noticed while I was at the dealer drooling over E92 M3s was that they're higher off the ground than my E93 328i.

I then went home and pulled up the data from the bmwusa site and my suspicions were (kind of) confirmed.

Doing apples to apples:

E93 328i = 54.5"
E93 M3 = 54.8", 54.4" (ZCP)

E92 328i = 54.9"
E92 M3 = 55.6", 55.2" (ZCP)

Unfortunately, there is no spec but I was eyeballing the difference from the ground to the bottom of the side bottom trim piece (which I think would be a better measure for clearance than the car height spec) when I noticed that it seems to have higher clearance.

-- EDIT --

I added ZCP numbers. 10mm = 0.4".

-- EDIT 2 --

I really wish bmwusa had actual clearance numbers posted. The height between the E92 and E93 are misleading because the E93 is not lower than the E92, it's roof just doesn't go as high since it's flatter due to being a vert.

I wanted a slightly more agressive look without the hassles of modifying so I am getting the the ZCP on my new car. That said, my 09 still looks badd ass.

I am with you on this Ian, I like to not be so high and just a touch from the eibachs are perfect for this car.

When I was at the dealer looking at the M I noticed that to.
The front does sit way to high, if the front sat like the rear did
I could have lived with it (maybe). Once you change wheels though
IMO a drop is necessary.

Not a fan of lowering with just springs. If I were to lower, I'd do the coilover route or shocks/springs.

I agree with this as well.

The proper way to lower a car is with a coilover kit.
It should be installed at an optimal ride height and corner balanced
to minimize "lean" when cornering. Most people though lower
there cars for looks.

The gap is ridiculous. Thats why, if the shit came just a half inch lower, i'd still drop it because thats how I ride, however that extra half inch might satisfy the normal person.

Just gotta say, after selling my 135i, most people don't care for mods and it can be a PITA when trying to unload. That's why I just ordered ZCP and don't plan any future mods (knock on wood) - especially not suspension .... other than maybe a new muffler

so I agree w/ you OP

I'm with you on the stock suspension although I do like the ZCP ride height as well. If I do anything there, it will be a ZCP retrofit.

i'm sorry you're a hater on my MonteCarlo M3, i bought it because i liked it. i'm not making fun of anyone else's car here, your comments are not appropriate. grow up son.

if you think lowering springs have rebound/damping, then you really don't know what springs are. kwv3's give you both rebound and and compression damping control. oops, sp mistake, i'm not perfect like some people here are. Here is the link for you to read and learn more.

I'm a patent attorney so I thought I'd chime in here - I for one love your paint job Monte CarloM3 .

Back on topic, I agree completely with the OP. Dropping the car really does make using the car as a DD appreciably more difficult - which is why I haven't dropped my car. But I have to say, even knowing this fact, I find myself dangerously tempted by the looks of a nice drop. It really does look THAT much better.
