The bottom mirrors are convex whereas the top not so much. I have these mirrors too on my 2nd gen (I was one of the lucky ones and ordered mine less than two weeks after they became available so yay for some money saving lol.) I love em- they shake at speed but not enough to be annoying and at any rate are no worse than my 92 F150. I am a pretty short guy at 5' 8" and have no problems.
