Hi All,
Not sure if anyone hates the oem "press fit" knobs like I do, but I got sick and tired of it after my last track event when the knob broke and continuously spun on the shift lever itself. Plus, I am not a fan of the limited availability of aftermarket knobs for BMW's.
My remedy was to make a new threaded adapter so that I could use some of my old knobs. The product is below. I made these on my crappy harbor fright lathe that decided to break down after my 4th prototype.
OD for the unit measures 19mm
What do you guys think?
