looking for spring recommendation...

Hey all I'm looking for spring recommendations for my 08 e90 with edc. looking for a small drop but i dont want to sacrifice ride quality and handling; if anything I'm looking for a improvement there as well. my car is street driven 99% Of the time but I'd like to do 1 track event this year. i hear good things about swift springs but again, I'm worried about ruining handling and ride quality.

thoughts?

The M3 does not have a lot of shock travel even in stock form, so any spring you go with will reduce the comfort level, it is just reality. Now how much worse the comfort, is subjective. Generally speaking, you will still be fine for a street driven car.

Swift springs are a good choice.

+1 for swift spec R springs

Drop is good and ride comfort is decent. Pic attached. These are on 18in wheels

My set will actually be for sale soon if you're interested.

Just get the shaved front shock mounts that Dinan does. Pretty sure others are selling them now too. I think they combine it with some other E36 M3 part to maintain travel in the stock shock.

There is little suspension travel stock so you need to restore it through cut down guide tubes on the upper strut mounts and E36 M3 bump stops. There is a thread on this by Malek. I think Dinan came up with the concept and uses it.

You could also add ground control camber plates which are supposed to have the same effect IIRC

I thought Swift was on the aggressive side. Eibach should be more oem-like

I had a bit different experience with Swift springs, but that's probably mainly dependent on the quality of roads in your area. You can find more info here

As far as handling, my opinion is that changing springs for stiffer and leaving everything else stock will result in less grip. Turner motorsport has an article on this topic, suspension stiffness must corelate with the grip your tires are able to provide, as well as road conditions.

If I didn't have a zcp I would go with Dinan springs.

Just stay on the mild side. I have been running H&R Sport for about 5 years. You will scrape your bumper undertray more if lowered

Hence the term suspension system. Nothing operates in isolation on a vehicle.

So you were ZCP prior to swift? I thought about ZCP springs on my 08 (obviously no ZCP offered back then).

Car has the competiton package, I bought it with swifts already installed and changed to new stock zcp springs.
Zcp has also different dampers and EDC programming.

Your thread going back to ZCP stopped me from going to the interim solution of swift springs + vorshlag camber plates before coilovers. I'm just going to stick to stock for now until I go coils.
