I vote for Happy on the Eibachs. They are good, the look is awesome. The ride is just slightly stiffer if at all than OEM. I bet there is zero improvement in performance than OEM and wouldn't be surprised if lap times were equal or even less the OEM. But I don't track my car so for the street I'm very happy with them. They definitely show a nice drop without being too low and causing any drivability issues.

H&R- no body roll on tight corners, marginal increase in ride stiffness, plus the drop looks great.

I voted "Happy"

AC Schnitzer springs:

Pros:
1. Nice drop
2. Feels tighter around curves
3. Not much stiffer than stock

Cons:
1. uncomfortable going over speed bumps
2. price tag for being AC Schnitzer

You're right about the patience part.

That was never my strong suit, as my wife often reminds me

I ended up waiting for 2 months for those, but they did finally show up.

Well, I guess I'm in the unhappy camp, since I went back to the stock springs. The H&R's looked amazing, but I'm faster on the stock springs.

Interesting, I would have though that with your M being a bit lower, stiffer springs & spacers that the CG would be lower and there for corner harder resulting in a little better track times. I haven't tracked it yet, nor am I a pro-race driver as much as I'd like to be but I find this interesting. Can you explain more why or how it's making a difference compared to OEM??

The rebound is off when you put any other spring besides the stock spring. The stock shocks were designed to work with the stock spring rates and height. With the stock springs, the shocks are working at optimum height. When you lower it, the shocks are suffering from more wear and reduces dampening capabilities because the shocks are not in their optimum performance level.

From my experience, with the H&R's, the handling suffers greatly compared to stock in "comfort" mode. In normal mode, on smooth roads I'd say it feels improved due to less body roll, but once you hit a bump stock feels much more secure.

Normal mode only feels good when you are on the turns (when the EDC is stiffening up), when you are just driving straight you can tell the rebound is slightly off.

In sport mode, the H&R's feel pretty good, I can't really tell if the rebound is 100% right, it probably isn't but I can tell you it feels much better. The only bad part, is that you lose the dynamics of EDC when you go in sport mode which makes EDC so great. Plus in sport mode, I feel it's way too bumpy on LA freeways.

For the money, you get great looks and a sportier "feel." But if you're anal or can tell small differences then you can see the softer the shocks go, the more out of tune the suspension really is compared to the H&R's. I still wonder why no one has made an aftermarket shock that can match RDSport/H&R's spring rates while making the shock shorter to compensate & work with EDC. I'll be waiting for about a year, if nothing is out by then, then KWv3's is what I'm getting.

I've been wondering myself why there hasn't been a spring/strut combo for the M3.. ideally i would want coilovers but being on a strict budget i prefer spending under a grand with everything installed

if i remember correctly the 335i's had a Koni FSD/eibach combo for approx. $650 that were ideal together.. most places even packaged them together.. but for the M3.. nothing
