Bestop traditional bikini freeway slap fix

For those of us running biking strap tops with that annoying slap going down the freeway.
Found a cheap and easy fix to get rid of it.

I took a piece of black foam and cut two 2" x3" rectangles and stuffed them at each corner of the sport bar.
Secure with a single zip tie or they will blow out.

"Slappy Noise" gone. Small win, I can hear my radio again at 60 mph.

A piece off the end of a pool noodle would work too, but the lime green color clashed with the red and black color scheme...
