Im looking into possibly getting the shark fin antenna for my mazdaspeed3 but first have a couple questions. Somebody who already has one what would be the dimensions (LxWxH). Also i would like to ask what do you all think about having a black shark fin on a true red? i like how the black stubby looks as an accent on the hood so maybe having a black shark fin would look really sharp, thats if its about the same size as the stubby. Has anyone already done this with they'rs, as in not having it painted they'r factory color?
