Question Loud/Nasty rattle when going over bumps

Was wondering if anyone else is getting the same sound/problem as me.

When I go over bumps, when the front wheel hits it, it's perfectly fine but when the back wheels hit it I get a loud nasty rattle.

The bumps honestly aren't big bumps and any other car I've had/driven, was never a big deal (just a thud sound/or a little rattle).

And to test it out I drove my bro's car which is a lot stiffer then mine (M45 with 19inch wheels + stiffer tires + springs + sport suspension) on the same roads/bumps. It does not even get close to the sound I get when my rear wheels hit the bump and on his car I just get a regular thud sound, no crazy rattle.

Tried to put it in comfort mode as well and it doesn't really seem to help.

I've got the dynamic handling + sport package.

Can't pinpoint exactly where it is coming from. I'm wondering if it has to do with either the sunshades on the doors/rear or because the rear is a multilink suspension
