HKS GR86 / BRZ TYPE-S Rear Diffuser

Overview

Enhance the rear aerodynamic performance and aggressive presence of your 2022+ GR86/BRZ with the HKS Type‑S Rear Under Spoiler — a purpose‑built exterior aero component designed by one of Japan’s most respected performance brands.

Aerodynamic Performance Meets Race‑Inspired Styling

This multi‑piece rear under spoiler features bold vortex‑generating fins and side extensions that serve both form and function. At speed, the design helps channel and control airflow beneath the rear bumper, increasing downforce and reducing drag for improved high‑speed stability. Its race‑inspired look adds visual impact whether you’re on the street, at the show, or hitting track day sessions.

• Aggressive Aero Design: Multi‑piece lower bumper spoiler with fins and side extensions adds purposeful detailing and functional airflow control.
• Performance Focused: Helps create a slight vacuum effect under the chassis to pull the rear end closer to the road at higher speeds, increasing stability.
• Versatile Use: Works beautifully as part of a full Type‑S exterior package or as a standalone enhancement to complement other body mods.
• Quality: CFRP & FRP engineered for both appearance and functional aerodynamics.
