Sachs "sporting" suspension. Any good? Will it fit

[MartinSE]

Someone is selling these fairly close to where I live. Claimed to lower the car 30 mm. They are for 45 mm struts. Can't find much information about them, they are probably quite old (stamp saying jan 1992) but unused. I have a pre facelift 12.86 320i. These seem to be for post 9.87, face lifts. Is the suspension different on the face lifts or would these fit? Price is around 250 quid.

Thanks
