I have bought a refurbed set of PSS9 suspension for my car from a forum member. I'll need to replace the top nut as it is one time use. Anybody know the thread and pitch, so I can have it here ready and waiting?

I think it's M12 1.5, but you should be able to look it up - or even send Bilstein a email...Good luck

They don't have any info on the pss9 anymore

I found the info in another thread - it's the same as the stock struts which is M12 1.5 pitch. (the stock struts are Bilstein as well)... Besides that, the "one time use" thing...Eh, if you're really worried about it throw a little blue loctite on it and mark it with a little paint or colored nail polish so you can tell if it has moved. I generally stick to the rules when it comes to fasteners, but I'm convinced that some of this stuff is just to drive sales (and of course to indemnify Porsche of liability should somebody do something really stupid). I think it get's torqued to around 60 ft lbs, so it's not going anywhere... (it's not like it's a crankshaft carrier or connecting rod bolt...). Good Luck

That's correct for the rear shocks. Front struts are M14 x 1.5.

when I did my B8’s with lowering springs I was able to get a pair of the top nuts for the front struts a a local Napa Auto Parts...
