My Ride: 99M3 cpe, 04M3 cab
Lowered M3 Convertible Pics (Eibach/Koni)

I spent hours on this forum and others trying to figure out the best suspension setup for my needs. Finally got everything installed today and happy to say no rubbing, wheel vibration, or other ill effects. Anyway, here's the setup I just installed:

Eibach Pro Kit Springs
Koni Adjustable Struts/Shocks
Macht Schnell Wheel Spacers (15mm Front, 12mm Rear)
OEM 15mm Rear Spring Pad
General Exclaim 245/275 tires

Height measurements (from center of roundel to fender) are 13.25 all around. I decided against coilovers because I wanted a simple setup, without worrying about adjustments, corner balancing, failing spring perches, etc. I did have to get my wheels balanced to eliminate vibration, and I'll get an alignment after everything settles. Ride quality is as everyone says... much less squat/dive, yet smoother on rough roads. Anyway, hope this is helpful to someone!

Looks about like mine (same suspension but I also have camber plates and sways). I too have been pretty happy with the ride quality.

My Ride: E46 M3 Vert
I have about the same set-up as you minus the Konis and different spacers:

http://www.m3forum.net/m3forum/showthread.php?t=368983

At first, I only installed the front Eibach springs but there was too much of a forward rake and the car did not drive right to me. Then I installed the rear Eibach springs, and that made the rear too low and tucked in the tire. The funny thing is, it sort of looked like stock b/c now the front had bigger fender gap than the rears. Finally, I installed the 15mm rear spring pads and it was just right The thirds a charm!

I'm leaning heavily on Konis after my stocks go out. Did you do the install yourself? It's a pretty easy DIY. Once you get to know one wheel the others are cake. You should drive over bumps slowly and load your car with 4 people to help the settling process.

You are right the install is pretty easy. I too started with just the H&R springs, then did the Koni's. My experiences with Eibachs have been the same as yours- the rear typically lowers further the the front. It happened on two friends cars and my Mustang. That was the biggest reason I went with the H&R's on the M3.

That drop looks absolutely perfect.

I have konis and eibach's sitting in my garage- should be installing them on my E46 M3 coupe this weekend...I wonder if the coupe needs the 15mm spring pads though..I assume the convertible is heavier in the rear is the reason it sags more.

Can someone chime in?

Yes you are absolutely right. Here is my old coupe with eibachs (I now have a vert):

That is nice- does that have the 15mm springs pads in the rear?

Is it an even drop like the vert?

All stock spring pads front and rear. It had a little bit of a forward rake as you can see in the pics, but slight enough that you wouldn't really notice it.

The verts drop lower because they're heavier.

Cool

Looks awesome. I'll holdoff on the rear spring pads then.

Thanks for your help

Are the wheel spacers necessary or just cosmetic?

Cosmetic. The struts and springs are the same size as stock, so there will be no clearance issues.

I have the same struts and springs, no spacers.

Cool. I was thinking that as the body came down that there was less tire clearance rather than more, so I couldn't see how there was extra room to "push" the wheels out even if you wanted to.

Hadn't heard of the spring pads before, but that sounds pretty simple.

I'm thinking about just doing PSS10s and calling it a day. They don't seem to list a separate part number for cabs, so I guess you compensate with a more firm initial suspension setting. I have a local suspension guru, and I'm confident that he can make short work of this issue

Coupes don't need them. Verts always sit like that because the springs people buy are for coupes and the added weight on a vert lowers the rear more than the front.

Good stuff - I am looking for a simple spring/shock setup and don't really care for coilovers at the moment.
