I think it’s just the sphericals at the bottom, but I won’t know for sure unless I replace the sphericals and swap the shocks again. Kinda just want to toss fresh Bilsteins in this pig and move on, but lots of conflicting info I never sifted through having always planned to do Vonns or coilovers.
Car is very light (<2200lbs wet) with 22/31 TBs and I’m officially accepting shock/strut recommendations.

I'm sharing this in case it's helpful (not stating your diagnosis is wrong) - I have Vonn Level 1 on my Targa (front and back). I had a similar issue but also had both a pronounced clunk on low-speed hits and same as you on high-freq bumps. It turned out to be the rubber bushings sandwiched by the top of the shock rod where the shock attaches to the body. I replaced those with factory Porsche bushings and it's been good since. The bushings I took out (and I think those came with the shocks) were hard and compressed after only a few years of use. The shocks have given me no other issues.
