Hi,
I want to install Bilstein B8 shocks and Eibach lowering springs on my 1988 316, but I'm a little confused about which to buy.
The description of the products I've been viewing mention two different strut diameters - 47 and 51mm. What's the difference?
Is there anything else I should know before buying better shocks and springs?
Many thanks,
Ollie

I think the sameller dia ,47mm are for the smaller engine cars (below 2.0 liter) and the 51 mm make up for the rest...................except the 318is and ALL tourings are 51mm . (I think.lol)

The two sizes refer too the physical size of your existing front strut tubes. Measure their diameter below the spring perches and the hub carrier.
A few E30 models (some smaller engined saloons mainly) were fitted with the smaller diameter struts, and you won't be able to fit a 51 mm damper insert inside of them .
