EXCLUSIVE FOR THE MUSTANG R-SPEC!
This unique optional Gurney flap from Herrod & Ford Performance can be bolted on to your existing spoiler with just 4 bolts to help improve handling and downforce.
With the Gurney flap in place in a track configuration, the 2020 Mustang R-SPEC conjures up 110 kilograms of rear downforce at 200 kph or 172 kilograms at 290 kph. This helps the high-performance pony car be even quicker around the track and/or road by gluing the car to the ground during high-speed cornering, braking, and straight-line performance.
The standard wing without the Gurney flap creates 60 kilograms of rear downforce at the same speed.
As simple as it may appear, the Gurney flap has drastic effects on airflow, especially at high speeds by creating two small vortices right behind the flap itself, both turning at opposite directions. Together, those two vortices create a rotating mass of air removed from the main flow, which leads to noticeable pressure on the rear of the car.
