Any reason why you didn’t go with Castro SRF? I’ve used that as well as Stoptech and Motul fluids and it seems much better to me. As far as compressibility and how long I can run it for.
I was getting this with the superpro LCA. It was the bushings and those spacers that are part of the bushing. Someone else on here with a white Golf R was having the issue as well. We both went back to stock LCA and the sound/knocking/clonking went away.
