I bought the FebiBilstein version of the 23711175939 (E30) here in Europe for my 325i E90 2006 and they fit fine and shifting is much smoother now than before. Can't compare to new genuine bushings as I didn't try those but the old ones had been on for 65 000 miles. Anyways thanks
feuer for the tip

I have some video of me twisting the old bushings while fitted to the gearbox without the supporting beam but I didn't film the same with the E30 style bushings so no real point to uploading that.
