This is the PERRIN Performance Gurney Flap. This is a subtle exterior upgrade that provides race-inspired looks with a little extra downforce. PERRIN designed this gurney flap utilizing professional flow analysis to decrease the overall lift of the vehicle while slightly increasing the drag. This is a great way to improve the overall exterior aesthetic for those of you who want a clean and sleek look without having a larger rear spoiler.
