Lowering/Performance Springs on 2021 M550i

Texox · 12-02-2020, 10:27 AM

Anyone know if there was any changes in the suspension for the 2021 model M550i as compared to the prior years' model? I am interested in dinan or other equivalent springs, but cannot confirm whether they will fit or not. I called dinan and they stated they have not been able to test out the new model, so they cannot confirm that the springs that work with the 2018-2020 M550i will work with the 2021.

I am interested about this as well.

So I received a message from tech support at dinan who said that there are not really any changes to the suspension between 2020 and 2021 and should be fine to run the springs and bump stocks on the new model. I do not know if I want to be the Guinea pig who tries it first...

... but am I very interested in getting them. I like that it is a subtle drop of 3/4in as opposed to some of the others that are a more slammed look.

I am wondering if it is advisable to wait to install springs and spacers until after the break in period? Or if it matters at all for the suspension?

If you get them, keep us posted! Thinking the same and wondering how much the suspension changes from stock, comfort, handling etc.

Just ordered my 550i xDrive. Has anyone had springs and spacers done yet. If so, what springs, how low and what spacers did you get?

If you change the springs does that affect the adaptive suspension at all?

And how will that affect the warranty?
