M Perf H.A.S vs. KW V4 opinions?
Hello guys,
Soon to be an F90 owner, i am already planning the mods and among them is the suspension. Since KW doesn't offer the DDC version for the F90, i am stuck between M Perf H.A.S and KW V4. I am not looking for maximum performance, but a more sleeker look with a nice drop. I know H.A.S has a max drop of 15mm while V4 of 30mm. My question is: does the H.A.S compromise the ride quality? I will not be tracking this car, but most like driving it on B roads rarely. Can any of you give an advice? Regards

For my new M5 I decided on the M Performance HAS. Previously I had KW HAS on my M cars. I chose M Performance this go round because of ease of purchase, install, dealer warranty, and being the M Performance brand. I am purchasing it with my car order and the dealer will install it when the car arrives. I like the idea that I will already have it installed when I pickup the car. Takes the hassle of ordering it and going to a tune shop to have it installed out of the picture. Plus any issues and it is covered by warranty. Going the safe and easy route this time. The only negative is it is more expensive doing it this way, but worth it to me.

M perf are coilover springs that replace the existing fixed-height springs but use the same dampers as stock. So you retain the adjustable ride, but gain adjustability in height too. Presumably the spring rate is going to be different but the amount is not reported anywhere. The installation instructions for BMW don’t specify any reprogramming of the adjustable damping so I’m assuming the spring rates are within bandwidth limitations of the factory damping settings.
