Hey Tom,
The guy who worked on my struts, asked me to come after sometime to collect them. He usually does this modification without allowing anyone to see the process.
I was curious enough to come a bit early and catch him in the act. He got nervous and asked me to come back later but I stayed lol.
Anyways, as you can see from the picture below, he removed the OEM cap off the strut and converted it to a screw type head with a normal on top screw cap.
What I saw him doing, was pouring a bit of ATF fluid inside the strut at the bottom before inserting the mechanism. Then he poured normal engine oil and closed the cap. This is the SECOND time I had him work on my struts, the first when one of them was leaking, I asked him to rebuild all 4 struts and make them stiffer. I think he close the original small hole inside the housing and drill a smaller one to make the oil move slower, hence resulting in a stiffer strut.
The second time was to install the adjustable coilovers. Now they are barely SHOCK absorbers, the feel is simply a bouncy ride as if welded to the chassis. Adding to that the full polyurethane bushings kit I installed too. Without even installing Nevin's bar, I can officially say that I have the stiffest SVX suspension in the World.
