This is it. I'm done. No more experimenting. This is just daytime placement for the STi so Leo's can't see it unless they virtually walk right up to my car. The bridge is made from 5"x .5" finished wood from home depot. Height is good enough. RD is sitting 1.5 inches above the dash level so there's no blocked view. It can't be seen from outside since it's sitting between my armrest and seats. Used 3M dual lock for the base for stability. I actually like this.
You don't need to do this if you live outside Virginia or DC.
