Some comparisons. Stock, Dinan and Eibach. I had H&R on my first M3 but don't have any pics. The lower I went, the worse the ride got compared to stock. Shaved mounts, e36 bumps on all setups. My favorite riding spring is the Dinan. The .5" even drop from Dinan (a hair lower than ZCP) is a noticeable drop albeit the most subtle, probably why it's the best riding.

Very good most of the time. On very rough patches of road they aren't as composed and comfy as Dinan. Eibach's are ~.3" lower up front compared to Dinan and about the same in the back.

I've always suspected that Dinan + spacers (15-12 front; 12-10 rear) + 255/275 tires = decent stance with no negative impact on handling. |

I'd stick to oem (especially if you have competition package), or Dinan.
All the other springs drop the front more than the real and screw up the car's balance. I've had H&R race and Eibachs. |

I generally feel like it should be all (coilovers) or nothing when it comes to suspension, but not sure I can justify the cost of coilovers or want the car that low for daily driving. Dinan seems to be a rare exception to the coilovers-or-nothing philosophy since they (1) do not decrease suspension travel, (2) don't dramatically alter the spring rates, (3) do not alter the geometry, and (4) don't drop it too low. That said, I must admit that I'm a little curious how the Swift springs with the rest of the Dinan kit would feel. |

"The rest of the Dinan kit" are bumpstops from E36, and a few millimeters shaved off the stock front guide supports. The springs are actually a fair bit stiffer than stock. It's a total fucking rip-off at retail prices unless you're buying super early in your car's life cycle and can really get a use out of that warranty. I bought a used set for $500 since my warranty will be up in a year and Dinan doesn't offer extended warranty on its parts.
Two important things to remember: 1. M3's bump stops are initially very soft, but when compressed to a certain length, they will become very stiff. The M3 has roughly 2.25 inches of compression travel. If you lower too much you would be constantly bottoming out on the bump stop. If you have four people in the car with stock springs, you are already sitting on the bump stops. This was my issue with H&R Sports, I had to drive it like a grandmother because it would bottom out on any bump. Using smaller bump stops like the E36 can help, but I think you really need aftermarket shocks like Koni yellows to really make super aggressive drops work. 2. The front and rear suspension are balanced to make the M3 pretty neutral (with a tad of understeer) when driven at the limit. If one end of the car is lowered significantly more than the other, that axle will likely bottom out, loose grip sooner, and change the balance of the car. I couldn't believe the enormous difference it made to switch to a more neutral rake. With the H&R sports (.4" differential between front and rear drop), the car felt like it was moments away from faceplanting the nose into the ground around corners and during hard braking. Eibachs (.2" differential) was a lot better, but the car still occasionally felt like it was precariously balanced on its tippy toes when I was really pushing it. Dinan took me back to factory rake, and I'm never going back!!! So basically, if you want to go with springs, go with Eibachs not because they are better, but because they are "less bad". If you search around, you'll find quite a few people switched from H&R to Eibachs and are quite happy. I still wasn't happy, so I went with Dinan. If I had a competition package car, I wouldn't touch the suspension at all except some camber plates and maybe a thicker sway bar, but you don't even really need the latter (I have the Dinan roll bar because I found a used one for $200, I like it).

Don't quote me on this, but if I remember correctly, Dinan stated their springs were 10% stiffer than the competition springs, which are in turn a tad stiffer than the Civic ones.

+1 on Swifts, they are incredible. I believe they are a little more aggressive height wise than Eibach, but they ride amazing. 110% satisfied with my setup.
Stock non ZCP: Swift Spec-R + E36 bump stops: P.S. The rear there seems to be a bigger gap than normal is because tires are 245 and stretched. Wasn't my choice, came with the wheels. Once 255 or 265 goes on, it'll look even more menacing.

Just to throw in my 2 cents on the Swift springs. I got em sometime mid last year i think and I highly recommend them. They ride great around town and actually do pretty well at the track too. They do settle quite a bit after you install them, so i would definitely do the e36M bumpstops AND trim your guide supports down some (similar to the dinan setup). If you don't do the different bumpstops and guide trimming you will be essentially riding on the bumpstops after it settles. Here's a pic of mine from about a month ago.

For you guys that installed the Swift's have you all used the OEM rear spring pads? It's my understanding the ZCP models have thinner spring pads for the rear. Was wondering if these might help keep the factory rake. I seen in this thread by Malek: http://www.m3post.com/forums/showthread.php?t=423572 he removes the spring rads altogether.
