RE: D3 E90 New Springs Advice?

[JWoods]

Hi all

Need to buy replacement springs for the rear axle of my 2011 D3 Saloon E90. Not too sure which ones are OEM or are acceptable for the car. Had a look on multiple websites and plugged in the vehicle reg nothing came up. Would ideally like to source the springs outside of going to BMW as they will skin me price wise.

I think eibach ones are the ones currently sitting on the car but honestly i'm not too sure. Any advice on brand / size (is that a thing?) of spring i should be going for?

Any advice appreciated!

Thanks,
J
