I have know how to do this for years but have never told anyone out of an agreement I made. The cat is out of the bag as evidenced by the picture on the
Attached ThumbNail at the end of this post.
I did this to my own car about 4 months ago with no problems but a couple changes.
I actually took about a 1/2 of inch off of mine and then drilled a 1-inch hole in the bottom of my strut. I then stuck that part the bolt attaché’s to thru the 1-inch hole and put a 1 1/4 inch bicycle headset spacer on the bottom of the strut and then the OEM Koni washer tightens down onto that. I was real worried about this moving around so a got some Magna ??? Epoxy and put that all over the bottom of the Koni before I inserted it into the cartridge. When it tightened down it squeezed all around the bottom of the Koni and chemically welded it into place. I also used some JB Weld on the top part. This lowered the strut about 1 inch in the housing. Don’t forget to get the weld on spring perch’s from G.C.. Makes a real nice setup. B.T.W. mine were old 70K+ on them and I know that Koni will not warranty any strut that has been used with lowering springs so I didn’t care about epoxying them into place.

Edit:
This is how they should look when you are done. After you do this cutting you put a good bead of JB Weld around the bottom ridge between the main strut part of the Koni and the remaining nob. Then another bead just below were the Koni sits near the top of the oem housing. All the JB does is reinforce the mechanical fastening so that it can never move. Do not do this with out the JB Weld as over time it will vibrate loose due to loading and unloading of the suspension forces.
For some reason the picture below is in the wrong place now. I can't seem to move it so here it is. This picture with the white car in the background is a GRM article picture about how to do this. My way is shorter but requires epoxy to be safe. Done right it is safe. I have never had a single unit come loose at the bottom.
EDIT: I NOW USE JB WELD ON THE TOP AND THE BOTTOM. Magana Weld is fine for the bottom but I prefer JBWeld.
