For those of you that use the car and would like to drink something, the cup holder sucks. So I have a simple "mod" that works perfectly.
With the cup holder out, you can use a flathead screw driver to remove the drop down stuff from the main holder. Use the flathead to pry the apart the tabs that hold the hinged parts.
Too much torque and the tab will snap off.
You can leave the front spring loaded lip. The cup holder then is simple a hole. Most mugs, including the BMW mug will sit lower and snugly.
I took the guts out of my and I am caffeined-up
My buddy and I were racing around the other day and my coffee stayed put.
Beware of non-ridged cups, Starbucks type cardboard wraps help.
Will not hold thin items like smaller water bottles.
