Stock Vs Coilovers
I'm still waiting for the aftermarket companies to come out with coilovers that adapt too EDC. Hopefully they are not too far away i will definately go KW!

I was a little confused with the numbers though. If total available compression is 2.875" but the bump stop is 2.375", then compression prior to contacting the bump stop is 0.5". So with a 1" drop you're already compressing the bump stop 0.5". Now you said that at 1" the bump stop will act like "rock bottom" although according to your graph, it looks like the non-linearity of the bump stop is closer to 20mm which is more like 0.75". Anyway, if we go with the 1" number and we're already at 0.5" compression, we only have 0.5" left and not 0.875" per your calculations. If we go with the 0.75" rock bottom number, we actually would only have 0.25" left right?

Second, the graph is just an illustration of a similar bump stop. Hope this helps. |

There is NOTHING official about Dinan anymore. That relationship ended long ago.

I noticed on my buddies car his EiBachs didn't even really drop it too much so I guess that's good too. My H&R Coils are just amazing, the handling on the car is much better then stock. I know your going to make fun of me later Lemans, but here is a question for you, when I went from my 285/25/20s in the rear to 295/25/20s it feels as if the handling wasn't as good as before, could this be? I am running 255/30/20s on the front. |

I've had my H&R springs on for over 10,000 miles and 8 HPDEs. I do not feel the handling on the track has been compromised, but I do feel it is not an ideal situation. For me this is not intended as the final solution; eventually coilovers will be the anwer.

That's why your handling feels different now, since you bought the larger rear tire size. (to fill up the rear wheel well) Larger tires and wheels will affect the way your suspension responds under compression and rebound. Keep in mind that our stock suspension was designed and tested with the stock wheel and tire sizes during R&D.

Do the chamber plates come with the Dinan spring kit, or is it an additional option? I know they have a few levels of spring kits.

The camber plates are a separate option. However I don't believe it will work with the stock suspension so you need to run their suspension to use them. (Although I think they make work with other aftermarket suspension set ups as well..

They will work with stock upper guide support, meaning you can add them to your stock suspension w/o their spring kit.

I think there's some lingering perception among M3 owners, that an aftermarket suspension setup can be fully compatible with the factory EDC option. Unfortunately, that's virtually impossible the way the EDC suspension is designed by BMW.

From what I've read from industry insiders, this will probably not happen because 1) the EDC system is quite complex (hence not justifying the R&D) and 2) there are IP protection surrounding the OE design.

... and probably the most important reason: the M3 market that will pay for EDC in the first place and then replace it with aftermarket EDC is insignificant.

+1 but when I got my M3 I had no intention of dropping it so now after some time i want to drop it and I should just have bought it without the EDC but then again, it works so awesome. But as far as looks go, it could need a drop and because of aftermarket springs works with EDC I will look over the bumpstop issue anyways, i mean, who cares? Just buy shorter once or simply replace them youself every other year or so.

Would you mind elaborating a little more please?
Not sure if I can afford any drop in ride height at all (driveway-related), but I was considering the Dinan springs... even so, I'd like to know what it was you didn't like about the H&R's... |

Well, both the M3 "Edition" package and the upcoming ZCP have a 10mm drop in ride height - and are available with EDC.
