Hello,
I am currently choosing a suspension for my car and have been lurking on the forum for a while to help me decide.
My dealer just told me of this new kit which, unless mistaken, was not yet mentioned on this forum. It is coming out in March. Eibach coilover system with Sachs dampers.

Very excited about this as, in my opinon, Eibach makes the most comfortable springs. I would have bought their spring kit if I could find a suitable shock for it like Bilstein B8.
By the way, Sachs also makes a coilover kit for the M2 but it has the same reference as the M3 and M4 - which I reckon is the same as stock suspension anyway ?
