I drive a lot on rough roads here in Norway. The springs had a much bigger impact on ride quality than my M5 Competition Pack front sway bar and M550d rear sway bar. I installed the sway bars over a year after installing my Eibach springs. The springs firmed up the ride and improved it. The sway bars aren't noticeable under normal driving but shines when cornering at speed. The sway bars was a MAJOR improvement for handling, without a noticeable downside in everyday driving!

Eibach Pro Kit springs has a super ride, not bouncy and a perfect drop IMO.

Update: Just purchased the H&R springs. Combined with the new tires I just put on, I think I'm in for some fun.

Another suspension upgrade to consider is wheels and tires. Ditching the runflats was good for a 7lbs weight reduction per corner. Buying some light weight wheels could push that weight savings up to nearly 15lbs. All of that weight savings makes it easier for your shocks and springs to absorb the bumps and keep your tires planted on the road.

What should the cost of a spring and bump stop install run? I'm thinking of getting mine done on my 550 M Sport.

It depends on where you live, but here in Southern California it's $350-$400 for installation. You'll need an alignment as well.

It's more uneven pavement that causes issues whenever you create a tighter coupling between both sides of the car. Any dip in the road that only impacts one side of the car causes the car to pitch more to that side rather than the suspension working independently. For some, the trade off of better cornering is worth it, but it's something to consider. If there was no penalty, the BMW would have designed the suspension with larger sways

I put on some BFG non-rfts and saw a big improvement actually

ACS is most expensive of all brands I've seen for springs alone. That and hardly anyone appears to carry them:

$741
compared to ~$300 ballpark for H&N or Dinan.

Does ACS really perform that much better?

I had my ACS springs installed by what I consider a very knowledgeable independent garage that not only specializes in BMWs, but successfully races them as well. I asked him the same question, and his answer was something like this: ACS springs are specifically tuned for BMWs, not only for ride and performance, but also to work well with the existing shocks and suspension. With my experience being only on ACS, I cannot compare to H&R or others, but I do find that the ride is better than OEM - it is just as smooth, but now more defined and more precise. I can take corners quicker and the apparent weight of the car seems to be somewhat reduced. Of note is that I also have the adaptive shocks and roll bars, and the ACS springs also seem to work very well with both of those systems too.

Because I can, here's a recent pic of my 535xi on ACS springs.

ACS is known to be the least drop for the F10 for those who don't want to go as low as what H&R gives

Might be the route for me in the future then. K&W coils and all other springs do too much of a drop for my taste since I'm concerned about going up driveways at some point :P

I like it too. That's what's so cool about carbon black. It really is a dark blue like you see here, and seems to change colour depending on lighting conditions. That photo is completely original - no photoshop or post-production magic on it at all.

I don't have problems going up driveways with my car as low as it is. it's called SKILL

When I was looking for our 2014 Carbon Black/black was a requirement. I LOVE the colour. Looks black here...

I had been looking at the Bilstein coilovers (PSS10). Adjustable height with only 1/2" lower possible (it is never clear if that means 1/2" lower than stock or lower than M-sport which is already like an inch lower than stock).

I did not like the reduced H&R race spring height on my 535i as I would scrape and had to back into my drive/garage all the time. (Although it handled excellent with the M5 front sway and H&R rear sway + springs.)
