E90 330D M-Sport Suspension upgrade options

Hi Guys,

I'm looking to improve the suspension a bit as I find the standard M-Sport setup a bit "skittish" on our potholed UK roads. Mainly I find its the rear of the cars that gets somewhat unsettled when pressing on through country roads.

The general consensus seems to be that the M-Sport setup is slightly oversprung for the dampers, at least that what others have said and it does feel that way....

So.... I've been checking out possible options, I've ruled out coilovers simply because my experience with them has been pure hassle and they tend to be quite hard with no give. I know there are coilover setups that are good but I'm just not going down that road.

This pretty much leaves me with simply upgrading the shocks and springs and with a bit of reading I had more or less settled on Koni FSD shocks and Eibach Pro springs. From what I understand, they more or less have an OEM ride height (a touch lower I hear) and the shocks are generally well regarded. Sweet..

But then I stumbled across a post about a BMW performance Suspension retrofit kit....

From what I understand, this is not the M-Sport suspension but something better, Does anyone have any experience with this kit?

Should I go down this road or stick with my initial thoughts of Koni FSD + Eibach Pro?

Thanks

EDIT: Looks like the kit I linked to is for the smaller engine models, the part number I need for the OE Performance Suspension is 33500444832
