D3 BT rear springs and shocks e90 saloon

[rednblack]

Hi,
Does anyone know the exact brand and model of the rear springs and shocks ? I have some part numbers for BMW from Alpina but still not crystal clear as there are options and I would rather purchase OEM but not via BMW as pricey, Alpina told me they use BMW parts but I think SACHS make the shocks and maybe Eibach/Bilstein some parts.

Someone must have replaced both with OEM as I believe quite common issues ?

Thanks,
Matt.

If you actually phone Eurocarparts with the part numbers, they can cross match and quote you a price for genuine parts.
