Concept of the Kit

A function-focused body kit designed to elevate the driving experience of the GR Corolla Gen 2

• A newly developed front spoiler specifically designed for the GR Corolla Gen 2 (facelift model).
• Redesigned to complement the GEN2 front fascia and updated vehicle dynamics, this front spoiler carries over the racing-inspired character of the existing BODY KIT TYPE-S, while enhancing the bolder, more aggressive presence unique to the facelift model and improving overall driving stability.
• Developed using aerodynamic analysis and 3D CAD modeling, the front spoiler integrates practical aerodynamics into a sleek and stylish form. It enhances front-end stability at high speeds, delivering confident and stable performance across a wide range of driving conditions—from daily use to spirited sports driving.
• Extensive real-world testing at Fuji Speedway, including repeated runs at speeds exceeding 200 km/h, was conducted to validate performance. Through rigorous testing under high-load conditions, the product achieves a high level of strength, durability, and reliability.
• The side skirts, rear bumper spoiler, and rear wing share the same design as the GEN1 kit, while the front spoiler is developed exclusively for GEN2. This approach ensures a well-balanced overall design and a high level of visual and functional integration with the vehicle.

Materials

Front Bumper Spoiler

• Inheriting the look of successive HKS time attack machines, it gives the GR Corolla a powerful impression.
• Carbon fiber barge panels are attached to both ends, providing ideal airflow streamlining and a subtle racing look.
• With an additional 45mm extension, the GR Corolla looks even more powerful.

Side Skirt

• Simple side skirts are designed to balance with the stock body design.
• While the concept is simplicity, the front is stylish so that the balance can be seen when standing next to the vehicle.
• The rear area is shaped to affix the HKS emblem.

Rear Spoiler

Wing Rear

●Performance

• In terms of performance, various positions and angles were considered and selected using CFD analysis to ensure that the air passing through the roof could be effectively directed under the wing.
• Smoke was used in a wind tunnel test to confirm that the wing shape was in line with the design intent.

●On-Track Validation (With / Without BODY KIT) at Fuji Speedway

• The performance differences with and without the BODY KIT can be clearly experienced.
• Braking stability is significantly improved.
• Understeer is reduced, and its onset becomes more progressive and controllable.
• Rear-end stability is enhanced.
• Vehicle behavior near the limit becomes smoother and more predictable, making the car easier to drive at high speeds.
• Repeated high-speed testing at speeds exceeding 200 km/h was conducted to ensure sufficient strength and durability.
