Good afternoon fellow F30ers. Spring is right around the corner and I will be removing my OE M442s with Blizzaks and installing VMR 710s in satin black with my OE summer tires soon. I'm considering mild lowering springs and several experts recommend the Eibach Pro-Kit over Dinan and H&R for these reasons; slightly more drop in front than rear (1"/0.06") and ride quality. I'm driving a '17 340i M-Sport RWD with Adaptive M suspension.

Disclaimer: I'm 45 and not looking for a "slammed" look, I have a competition license and have raced BMWs for years, I am not looking for major discussion on ultimate "handling dynamics." I'm seeking a quality ride for daily driver and enhanced look by partially eliminating the huge front fender gap these things have stock.

Thoughts?

Do you have an Eibach Pro-Kit part number for your car? Their website application guide still doesn't list the F30 340i RWD, only AWD. I contacted tech support a year ago and was advised they hadn't yet confirmed 340i fitment. Surprised it's taking so long for the RWD version.

Seeing that too.... I was told the part number is the same as F30 335i RWD which I'm not really buying. Geometry may be the same but as you guys know there were significant changes from the 335 to the 340 as far as components go. Gonna sit tight for a bit (and may actually just live with the gap). Thanks!

PS Although it appears the H&R part numbers are the same for 335i and 340i, am I correct? #28878-2 on Tire Rack & Turner.

There's a number of people on here running the ACS springs including myself. I would recommend any day over HR or Eibach for mild lowering. Esp for winter use.

Thanks JWW. Mind sharing where you purchased them and are they a specific part number for 340i (vs. simply "F30...")?

ACS have a similar drop to the H&R sports.

Sure, I purchased from TAG Motorsport... they are one of the sponsors on this forum.

Check out the AC Schnitzer website and they show all the various spring kits. There's a ton of distinction between body styles, engines, and drivetrains.

No the HR are significantly lower... most notably the front drop.

We're talking about .2 inches in front and the same drop in back. The difference is not material. Now if you're talking super port springs that's different

Real world vs specs on paper... take a look at the pics floating around.

Once again, my car is RWD, NOT X-Drive.

Eh, not necessary for street use. Cheap "coilovers" are inferior and expensive multi-way dampers are total overkill. In my opinion anyways....

I am telling you, in the OPs car. You won't be able to tell the difference visually or while driving between the 2. We're talking fractions of an inch difference
