BMW F06 springs

[Aesthetic]

Hi guys. I see a lot of people rides on H&R Springs but there are also other well known companies. I found:

1) H&R - front 30mm rear 15mm drop
2) Eibach - front 25mm rear 20mm drop
3) AP - front 30mm rear 20mm drop
4) ST - front 30mm rear 20 mm drop

What is wrong with those companies? Why everyone buy H&R if there are also other springs that offers more aggresive rear drop?

Good question !!!!!

I've bought Eibach springs for 4 times and first 3 swaps have had enjoyable end, those last ones are still in my garage and waiting to get under my F13.

Yes, different 'body' but still.

I went eibach, nice ride and not to aggressive for the speed bumps as I have a front splitter

Could you share photo of your car dropped on Eibach springs?

There's also Megan Racing springs, which claim 1.25" (or 30/31mm) drop on all corners. In my opinion, BMW's in general usually sit a bit lower in the rear already, so perhaps that's why H&R is so popular.

I am considering doing a 1" drop in the front, but leaving the rears alone.

Is there anyone running on AP springs?

I wouldn't say anything is wrong with any of the companies. Different preferences.

Everyone doesn't want their car dropped that low (H&R) due to:
- ground clearance
- ride stiffness

- H&R has a raked stance lower in front, small drop in rear
- Cost

Exactly my reason for avoiding H&R - drop and road clearence

Mark thanks for posting photos. I like the way H&R drops at the front but would like something lower at the rear. It's tough choice.

I’ve always gone with Eibach over the years.

Did you leave out KW HAS for a cost reason or ?
They are adjustable to: 5-30mm Front / 5-25mm Rear

Me too !!!

What set you've in your 640 ? Just curious how much my car is likely to be dropping with Eibach 25 mm. /20 mm. set.

Haven't done the 640 (yet)

You need to be careful lowering a car on stock shocks too much by just changing the springs, because too much and the shock doesn't operate as it should, as its in a permanent state of compression, rather than being allowed return to it's normal "neutral" position; thus there is an increase risk of premature shock failure.

Believe Alpina use (or certainly used to use) Eibach on stock shocks, hence that was good enough for me.

I decided to go with H&R but even I'm driving 650xi GC, I bought set for 650i Coupe. With this setup, front drops 30mm and rear about +/- 25mm.

Body does not make that big difference but the 4 wheel drive does - as far what I know front springs are different from RWD.

Before h&r did separate springs for xDrive, in 2013 peoples with 4wd were running on 2wd version. Also for example Eibach sells the same springs(one part numer) for 650i and 650xi.

Hmmm, interesting information !
