E89 Rear Coil Springs

[Zed Baron]

Ok E89ers, are the rear coil springs (OEM) the same on all models?

There is definately a difference between 3.0 M sport cars and smaller engine cars, it's not much though, maybe 5-10mm

There were two sets of differences...

MSport versions had approx 15mm lower springs

Between the different engine versions there were different spring rates on what appeared to be a haphazard / or finely tuned basis.

I found a table that listed them all, there were weird ones like 28i auto having different to 20i auto and things like that...

The actual spring rates and dimensions for the OE parts I couldn’t find..

Can’t remember if the springs on the electronic dampers were different again..

If I can find it I’ll post it..

Most people go for aftermarket versions when they change/replace..
