Eibach pro or Sachs M sport springs on SE??

So I bought some Eibach pro springs for my 325d E91 as the SE springs are a bit wallowy and not very planted. Just want that planted feeling I had in my old E46 with sports suspension.

Then I got to thinking g it would be too low and maybe too stiff so I got a set of M sport springs by Sachs from ECP.

I have a set of Bilstein B4 for sports chassis that will be going on regardless.

What do you guys think Eibach or Sachs M sport???

Don't want to scrape speed bumps and want to be able to resell the car one day.... Not for a good few years tho!

Whichever set I don't use I shall sell on.

Eibach all the way as I believe they are superior. There are lots of us on here who have BMW springs explode whilst driving lol.

I can vouch for that, my E91 has 91k miles on and a front spring cracked last week. I have replaced them with a set of Eibach pro kit set of spring, my car is a sport already so it only lowers the front 20mm and the rear stays the same. It looks good and fine though, hopefully they will last a further 91k miles.
I considered replacing the shocks at the same time due to the mileage but as it was already a surprise cost I have left them for now. Once one leaks at MoT time I will replace all four.

I have a 2006 E90 330d SE. The dampers will make the most difference. I found the OE ones had a small window where they worked ok - very load/temperature sensitive - especially with RFTs.
I had Koni FSDs fitted with the oe springs at first (100k - 115k miles) as ride quality was my priority as the suspension was making long journeys tiresome.
Then a rear spring snapped so i upgraded to EPK springs and have run like this from 115k-130k miles. The drop is just right. I get a lot of comments that the car 'sits well'.
The ride is firmer but not in a detrimental crashy way. The handling is improved further with even less roll/squat/dive.
The only negative with this combo, and this has been posted by others before is the bounce from high speed sharp undulations, where the FSDs seem to get caught out. But it's 90% there which is the best thing i have done to this car.

Eibach Pro springs are less harsh/crashy than the M-Sport springs. One of the reasons why people with M-Sport models upgrade to Eibach.

My car had SE suspension and I upgraded to Eibach Pro springs a few years ago now, they are nicely matched to a set of Bilstein B8 dampers. and they completely transformed the car!

Not had an issue with speed bumps.

Definitely the ProKit. You shouldn't have any issues with speed humps and the like on them as they aren't overly aggressive.
