HKS TYPES Duck Tail Spoiler - 2022+ Subaru BRZ / 2022+ Toyota GR86

TYPE-S Duck Tail Spoiler for the 2022+ Subaru BRZ and Toyota GR86

The HKS TYPE-S Duck Tail Spoiler for the 2022+ Subaru BRZ and Toyota GR86 is a deck lid spoiler that provides rear downforce through the classic duckbill profile. A low, integrated-looking form that generates downforce without the height or commitment of a full GT wing. On the GR86 and BRZ, the duck tail is the rear aero piece that fits the car's character: aggressive enough to function, restrained enough to drive on the street without looking out of context.

22-Degree Trailing Edge, 8-12 kg at 200 km/h

The duck tail profile generates approximately 8–12 kg of rear downforce at 200 km/h in isolation, modest compared to a full wing, but meaningful on a car weighing approximately 1,270 kg (GR86 curb weight). The trailing edge angle is 22° from horizontal, which HKS's wind tunnel work identified as the optimal angle for the GR86's rear roofline exit geometry. A shallower angle produces less downforce; a steeper angle increases drag disproportionately to the downforce gained.

Duck Tail Aerodynamics Without the Wing Commitment

The duck tail profile works by creating a pressure differential across the upper and lower surfaces of the spoiler as air exits the rear of the car. The angled trailing edge forces air upward, which creates downforce on the rear deck. The low height of the duck tail keeps the effect proportional. Meaningful at speed, not generating the dramatic rear bias of a tall wing setup.

Works Best as Part of the Full TYPE-S System

The TYPE-S Duck Tail is designed as part of the HKS TYPE-S aero package for the 2022+ GR86 and BRZ, coordinating with the front lip, canards, side skirts, and rear under spoiler in that family. It works as a standalone piece but the aerodynamic balance is optimized when combined with the front TYPE-S components.

The FT Breakdown

The duck tail is the right rear aero choice for GR86 and BRZ owners who want functional downforce at the rear without the visual statement of a large wing. It reads as part of the car rather than added to it, and HKS's design is consistent with the TYPE-S direction established in the rest of the aero family. The 22-degree trailing edge angle is the result of HKS optimizing the duck tail for the GR86's specific rear roofline exit geometry. A generic duck tail applied to a car it was not designed for often produces more drag than downforce because the exit angle is wrong for the airflow path off that particular C-pillar. HKS's application-specific angle avoids that problem.
