KW coilovers. Pretty adjustable to what you like.

EDC equipped

Just a little stiffer than stock. But handles way better. Steering is quicker and the car feels more agile. I wanted the KW sleeve kit and i know they are great but the last time i had adjustable suspension i never really adjusted them.

My buddy has KW and he thinks mine rides better.

But of course the real question is do you want to lower it or just get rid of the wheel gaps. This is why i settled with Eibachs.

Bottom line. You cant go wrong with either.

This is the perfect description for wanting lowering springs! Because it's exactly what it will do for you.
But if you want something more? Then coil-overs are the way to go.

The truth is most people that start with springs end up wanting coilovers because overall, they're better. Coilovers allow you to be adjustable, I'm sure you can even have the car almost at stock height with the right kit, while springs is one height, and what if one end starts sagging eventually? The installation price for springs and coilovers are about the same as well. Most of the time they will ride better than springs too. I haven't had too much experience with the e9x platform since I just got my m3, but it's usually the same with any car.

Do you have wheel spacers? Clean hubs and reinstall.

Alignment? Go to a performance shop or BMW dealership. Pay one time and get it done right.

I'm from the UK, and finding a reputable Bmw specialist is very hard, the last "specialist" I found started to use his fingers to measure the gaps, hmmm 2 fingers this side and 2.5 this side.. Waste of time and effort, I was like wtf is this dude on about lol.. He was recommended on here by a few people.

if you have EDC and want to retain that, then spring kit. I just picked up Eibach Pro Kit. Can't wait to install. Though the install itself will cost 3X the price of the springs.
My goal was to eliminate wheel gap and slightly improve handling while maintaining stock ride.
Also, i hear bump stops are not necessary. Any opinions on this fellas?

Let me know once you've installed the kit, I think I might be getting the same kit, don't mind Installion fees as long as they get the job done to a high standard.. No cow boys or butchers..

I'm running "H&R sport plus" springs. They are great, good ride and great peformance! I favor them over the eibachs. And I've always run eibachs on my other cars in the past!

I did an extensive search about this when I was doing my suspension/spacer work.

I've had several coilovers in my previous car and although it may handle well and be stiff, I didn't want to sacrifice the ride comfort with another coilover.

I love KW coilovers, also thought about Ohlins for my M3, both are great
but no matter how the setting is done, coilovers will always be more stiff than spring setup. Obviously there's always +/- to every setup

I had 359M rims and wanted a subtle, yet nice looking and riding setup for my M3
went Eibach springs (a bit softer than H&R). Swift springs are also good product to consider if you want to go springs

If you want a slightly more aggresive lowering, go Swift.
If you want more stiff ride, go H&R
If you want a subtle lowering with almost stock ride, go Eibach





My setup is Eibach pro kit + 15mm/12mmspacers + OEM 359M rims/Conti tires
hope this helps!

Get some sticky tires and you will enjoy great handling and better braking.

I've been running H&R coil-overs for the last 3 years and really like it!

I like my KW H.A.S. Let's me get a perfect stance dialed in while still retaining stock EDC.

This is with Eibach springs:






And, this is with the height adjustable sleeves (not the best angle to show the difference, but it's very apparent).




The ride on them is smooth, because you're still using the stock suspension...minus the springs. The new bumpstops that come as part of the kit help with the travel comfort as well.

Michelin PS2 is a weak tire. If you were interested in handling, get at least something like RE-11's, RS-3's, Star Specs, or similar. These will change your handling far better than a cheap set of coils on PS2's. Just my opinion of course.

Hey suspension gurus, I am in same boat as OP. Would anyone recommend using the BMW OEM Competition Package springs for a modest drop? Any advantage over either of the Eibach or H&R offerings?

Why have B&G Springs not been mentioned. Awesome spring and perfect height.
