Review on Improved SEO: Black Non-Threaded Gear Shifter Adapter 1.2x1.25 for BMW/VW with SpeeVech Shift Knob Compatibility by Andrew Webster

I've had a lot of trouble keeping this thing locked in my 03 a4, tried loctite etc but even then 3-4 casts came loose after about a week. I ended up using a two part solid epoxy and potting the inside of this adapter, then placed it on top of the shift knob with a piece of cardboard underneath to prevent movement and then tightened the screws as tight as I could. Let it set overnight and I haven't had any issues or complaints with my shifter since using a 450 gram Blox shift knob.
