HKS GR86 Body Kit TYPE-S ( Full Kit Unpainted)

A dress-up aerodynamic device designed with functional beauty in mind

■ Concept

An original body kit that conforms to safety standards and inherits the HKS racing style and expresses strength.
The stylish form is the result of aerodynamic analysis and 3D CAD modeling, and aims to improve driving stability.

●Front spoiler

It inherits the look of HKS’s past time attack machines and gives the GR86 (BRZ) a powerful impression.
Carbon barge panels are attached to both ends, creating an ideal streamlining effect and a subtle racy look.
In terms of performance, an additional underpanel has been installed with attention paid to the flow of the floor. This has achieved increased downforce while suppressing drag.

Canards

The running wind is accelerated in a spiral (low pressure) and the turbulent airflow (high pressure) inside the tire house is expelled. The aim is to reduce lift by reducing the pressure inside the tire house.
Also, the beautiful twill weave carbon fiber gives it a racy look.

●Side skirt

The sides are beautifully designed to make use of the original press lines, while the large, powerful barge panels create a powerful impression.

●Rear spoiler

To make the most of the effect of the front spoiler, it is also important to streamline the airflow around the rear. The streamlining effect of the unique fin shape optimizes the aerodynamic balance between the front and rear. In addition, the carbon barge panels on the sides give the car a powerful, wide feel, just like a racing car.

Ducktail

The ducktail creates a streamlining effect on the upper surface of the body at high speeds, and together with the streamlining effect on the lower surface of the body, it improves downforce, improving tire contact with the ground and driving stability.

●Rear wing

• The main wings and wingtips are made of lightweight, race-like CFRP (twill weave), and the aluminum struts are painted matte black for a stylish look.
• The wing cross section and Gurney flap shape were designed using fluid analysis to achieve low drag and high downforce.
• The support pillars are attached using a specially designed reinforcing bracket structure to prevent fatigue damage to the trunk panel from repeated downforce loads (MAX Speed: 210km/h).
• Driving tests on a vehicle equipped with a rear wing and aero kit have revealed improvements in driving stability that the driver can clearly feel, such as reduced understeer when entering corners, greater stability when cornering, less wobbling during full braking, and an improved sense of tire contact with the ground.
