As a huge FC (86-91 RX7) enthusiast, I wanted to make one of the cool and rare OEM features of the FC a reality for the NC Miata (’06-’15). On the RX7, this item was found on only a handful of models, and successfully lowered the car’s coefficient of drag in wind-tunnel tests. (.31 to .29, in conjunction with the rest of the cars aero kit). No doubt does this smooth out the flow of air going under the car, helping keep wind noise down, while keeping aerodynamics & highway fuel economy up.
