O.K. here I go, my first entry.
I've been kicking around the idea of strut inserts on my Mcphersons. I put the AC coils on 2 years ago and was just not happy at all. First of all, I read all the problems with them here at NPORA and what a B%#@H putting together and installing. The drive shaft angle and the top out issue was bugging me so bad that I machined some strut rod extentions #pics and /or drawings coming# that I put on the end of the rod in order to lengthen the rod. This was to remedy the top out issues. I now have decided to do a SFD to correct the drive shaft angle and to level out the vehicle due to the AC springs being too tall in the rear and creating excessive rake. The strut rod extensions were a great idea theoretically but one of them broke just recently. I didn't consider torsional stress on the attachment area and thought "incorrectly" that the rod would only receive vertical pressure. It snapped at the OE portion of the rod right at the top leaving the threaded portion in the extension. So back to the drawing board.
I searched high and low for ideas and came across Koni Heavy Track strut inserts part # 86 2582. Basically, you cut the top off your strut housing, pull the guts out and insert the Koni shock and attach at the bottom.

So, I'm going to put a 2" spacer in the bottom of the strut housing in order to lengthen the strut and prevent top out and/or centering the rod in the shock as well as aid in spring installation. The Koni's are rebound adjustable and definetly a superior part compared to the KYB's and anything else. Koni wants you to measure the top of the strut and cut it down according to a subtraction method in order to facilitate proper insertion depth. Therefore, leaving my housing long and putting a spacer at the bottom with a longer bolt should work out for me. I don't think that an acceptable portion of the of the insert sticking out above the strut housing will cause a failure.
Photos as soon as I figure out how to download them.
