yes, i know of the belgian guy and his switch from drexler to osg and that he was very happy afterwards.
anybody i know of driving an osg is happy with it... except me :-(
i dont think my unit is bad... as i wrote i guess it was set with too much negative preload (4x 3x 28kg springsets). i'll definitely give it a second try with the new setup that should lock way harder than the spec-s setup!
here are some detailed pics of the assembly and installation:
when recently disassembling my failed unit i double-checked everything for possible failures or so. everything looked fine.
