This is apparently a fairly popular modification where you cut the top off of E36 m3 struts, remove the guts, drill a hole in the bottom and insert a Koni Sport insert. Not only E36, but many other cars where Koni has suitable inserts
Just for info some DIY links:
I should have known that earlier, actually I replaced 2 years ago both my original Sachs-Boge E36 M3 front struts with
312253 Sachs-Boge OEM - Strut Assembly; Front Left; OE Version
312252 Sachs-Boge OEM - Strut Assembly; Front Right; OE Version
and 'unfortunately' scrapped the old ones as both were leaking at the top with less than 50k miles, could have bought Koni sports inserts
Nice DIY, thanks!
Wish I hadn't cheaped out and got our Meyle Sport damper replacements now. That GC setup doesn't seem to expensive, but for me, the stock Sport (-15mm) is ok and for mum any lower would mean big problems in the supermarket carpark. But the installation is at least super easy, yay!
If only the e32/e34 front strut had that neat removable knuckle/strut design. (I wonder if it would be possible to retrofit it somehow, i.e. by sacrificing a set of e36/e46 struts)?
