I am using this. Can't get any cheaper and more stealth than this. I stick the metal plate inside the case so its completely invisible from outside. The vent mount is very clean and perfect location for phone operation...
Its actually really cheap consider its a one off custom job. He only charges 49$ for a single color.
you can come up with your own design, the guy can do anything. It may looks a little flat from the picture, but its actually 3D and painted/cleared.
If you want my design just sent him that...
If you get an adapter you can use any shift knob with M12x1.25 tread. a typical stainless ball one will weight at 500gram and cost around 40-50$. I have a knob made out of natural hematite rock, weight is at around 375gram.
downside is it does increase the height by an inch.
from what I have seen, nothing is a perfect match since.. all the lights are in different color coming from factory. Headlight, DRL, and fog light all in different color lol..
