Suspension upgrade

Rob Charles
in BMW 4 Series Forum

Featured Replies

Hello all. I have a 2019 M Sport+ 440i. I am looking for suggestions to upgrade the suspension. I do not want it lower or stiffer. I am looking for more control, predictability and less harshness. At under 20k miles, there are no faults with the factory suspension, I believe it could be better. I don't drive the car hard, its more like fast touring.

I am aware of the Bilstein system that Birds BMW have developed, does anyone have experience of this system? Any alternative suggestions would be appreciated.

    Welcome to the Forum

    By the sound of things you need a coil over kit for standard ride height with adjustable shocks. Playing with bump and rebound settings should allow a more supple ride, though wheels and tyres are a big part of the overall equation.

    Bilstien are a well established reliable name that has been around for years so if the kit has been developed for the car should be a good choice, lots of other kits out there with a wild price range but personally suspension tyres and brakes really are not worth cutting corners with.
